Chesstalt

Four game modes. Eight leagues. Every piece deployed from move one.

How to Play

Quick Rules

The Board

Chesstalt's signature mode (Duel) uses a tight 4×8 battlefield — files c through f only. The other three modes (Brawl, Siege, Conquest) use the full 8×8 board. Every piece starts fully deployed. No opening phase. The fight begins immediately.

Turn Timer

Each player has a fixed time per turn — 60 seconds in Chaos, 30 seconds in Classic. The bar drains in real time. Run out of time and you lose instantly. No exceptions.

Winning

Checkmate, opponent timeout, or reducing them to a Lone King — all instant wins. Stalemate decides on points: Queen=9, Rook=5, Bishop=3, Knight=3, Pawn=1.

Sacrifice & Banked Moves

In Chaos leagues, sacrifice your own pieces to earn extra moves — one immediate plus banked moves that automatically pay out at +1 per turn. Sac a queen, gain three turns of move-superiority. The bank caps at 3; same-turn bonus caps at 2.

Trade

Sell pieces into a points pool and buy different pieces of equal or lesser value mid-game. Three pawns for a knight. A queen for a rook plus change. Reshape your army on the fly. Chaos variants only.

Brawl

2v2 on the full 8×8 board with two Chesstalt setups stitched together per side. Each player controls their own pieces (starting in their half), but pieces move freely across the entire board. Win by capturing both enemy kings.

Eight Leagues

Four modes (Duel, Brawl, Siege, Conquest) × two variants (Chaos with full mechanics on a 60s timer, Classic with pure chess on a 30s timer) = eight playable leagues, each with its own ELO rating.

Ranked Pools

Ranked mode requires 25 games — but the pools are separate. Duel and Conquest count toward your 1v1 pool. Brawl and Siege count toward your 2v2 pool. 25 Duel games unlocks 1v1 ranked. 25 Brawl games unlocks 2v2 ranked. Progress carries across modes in the same pool.

Chesstalt — quick reference

For a guided walkthrough, see the Tutorial. This page is the lookup reference.

Overview

Chesstalt is an original fast-paced chess game. Across four modes, every game starts fully deployed — there is no opening phase. Combat is governed by a per-turn timer, and the player who runs out of time loses immediately. Layered on top: banked moves earned through sacrifice, an in-game trade system, and a Lone King win condition that ends games once an opponent is stripped of pieces.

The Board

Duel uses a 4×8 board — a standard chessboard with files a, b, g, and h removed, leaving files c through f. Eight ranks remain. Brawl, Siege, and Conquest use the full 8×8 board.

Starting Position (Duel)

Both sides deploy all pieces at the start. From rank 8 to rank 1 (Black perspective): Bishop–Queen–King–Bishop on rank 8, Rooks on the outer squares of rank 7, Knights on the outer squares of rank 6, four Pawns on rank 5. White mirrors on ranks 1–4. Conquest uses standard 8×8 chess deployment.

Turn Timer

Each player has a fixed number of seconds per move. The timer resets after every move. Running out of time is an immediate loss — no extensions, no delays. Timer duration is set by the league format.

Chaos60 seconds per turn (full mechanics)
Classic30 seconds per turn (no sac/trade/banked)

Winning Conditions

Checkmate — place the enemy king in check with no legal escape. Instant win regardless of piece counts or remaining time.

Timeout — opponent's per-turn timer reaches zero. Immediate loss for them.

Lone King — opponent reduced to nothing but their king(s). Automatic win, no formal checkmate required.

Stalemate / no legal moves — game ends; player with the highest piece point total wins. If equal, it is a draw.

Piece Point Values

Queen9 points
Rook5 points
Bishop3 points
Knight3 points
Pawn1 point
King0 points

Sacrifice & Banked Moves

Available in all Chaos leagues. Click Sacrifice on your turn and select one of your own pieces to remove it from the board. In return, you earn bonus moves — one extra move this turn (the immediate bonus) plus banked moves that automatically pay out at +1 per turn until the bank is empty. The king cannot be sacrificed.

SacrificeImmediateBanked
♙ Pawn+1 move
♘ Knight+1 move+1
♗ Bishop+1 move+1
♖ Rook+1 move+2
♕ Queen+1 move+3

Banked moves cap at 3 per player; overflow is lost. Bonus moves this turn cap at 2 — so a bank-payout (+1) plus a same-turn sacrifice (+1) reaches the cap and can't stack higher. Sacrifice locks the Trade button for the rest of the turn (and vice versa).

Trade

Click Trade on your turn to sell pieces from your half into a points pool and buy different pieces of equal or lesser total value. Buy-value cannot exceed pool-value; any leftover points come back as change in the form of smaller pieces (chosen automatically: largest possible). The king cannot be sold. New pieces enter via a placement step on the same turn but are frozen for the rest of that turn — your normal move comes from your existing pieces. Trade locks the Sacrifice button for the rest of the turn (and vice versa). Available in Chaos league variants only.

Lone King Redemption: if a trade leaves you with only your king, the system places your bought pieces immediately so you have something to defend with. Your turn proceeds with your king's move (the only un-frozen piece you have).

Modes

Duel — 1v1 on the 4×8 board. Signature Chesstalt format.

Brawl — 2v2 on the full 8×8 board. Two Chesstalt setups stitched together per side; each player controls their own pieces (starting in their half) but pieces move freely across the entire board. Win by capturing both enemy kings (or reducing the enemy team to only kings). Turn order: White P1 → Black P1 → White P2 → Black P2.

Siege — 2v1 on the full 8×8 board. The Solo plays a classical chess setup (top of the board) and gets two moves per cycle; the Team plays two Chesstalt halves at the bottom and each Team player gets one move per cycle. Cycle order: Solo move 1 → Solo move 2 → Team P1 → Team P2. Solo's classical setup supports castling and en passant; the Team's Chesstalt halves do not. Solo wins by eliminating both Team players (king capture or Lone King). Team wins by capturing the Solo's king or reducing the Solo to Lone King.

Conquest — 1v1 on the full 8×8 board with classical chess piece deployment. Castling and en passant active. Available in both Chaos league (full mechanics + classical setup) and Classic league (pure chess on the timer).

Standard Chess Rules

All standard chess rules apply within the board constraints. You cannot move into check. Pawns promote on reaching the enemy back rank. White always moves first. Castling and en passant are mode-dependent: both are available in Conquest and for the Solo player in Siege; neither is available in Duel or Brawl due to compressed starting positions.

Leagues

Each mode has both a Chaos league variant (full Chesstalt rules — sacrifice, trade, banked moves; 60s per turn) and a Classic league variant (chess on the same board, no sacrifice / trade / banked moves; 30s per turn). The lone-king win and stalemate→points rules apply in both variants. Eight total league variants. Each league tracks your ELO separately.

ELO Tiers

Every league tracks your ELO separately. Play 25 games in the right pool to unlock Ranked mode (1v1 pool: Duel + Conquest games combined; 2v2 pool: Brawl + Siege games combined). Your ELO starts at 1000 and adjusts after every ranked game.

Designer's Note

Chesstalt was designed as a fast, aggressive alternative to standard chess — a game where every piece matters from move one and matches resolve in minutes rather than hours. The narrow board forces tactical play. The timer keeps energy high. Banked moves and trade create decisions that don't exist in any other chess format.

Path:

Welcome

Chesstalt is a fast, aggressive take on chess. Across four modes, every game is designed to start in full combat — no slow opening phase, no long wind-up. The goal of this tutorial is simple: when you finish, you'll know enough to play your first match and not feel lost.

You picked the new to chess path. We'll start with how chess itself works — board, pieces, the win — and then move into what Chesstalt adds on top. If something feels obvious, scroll past it.

The Board

Standard chess is played on an 8×8 board — 64 squares, alternating light and dark. Columns are called files and labeled a–h from left to right (from White's perspective). Rows are called ranks and numbered 1–8 from White's side to Black's.

Each square has a unique name: e4 means the e-file, fourth rank. You'll see this notation everywhere in chess — it's how moves are written down.

Quick orientation tip: White's back rank is rank 1, Black's is rank 8. Each side starts with all 16 pieces filling their first two ranks.

The Pieces

Each side has six types of pieces. They move in different ways, and learning each one's pattern is most of what early chess is about.

Pawn×8 · 1 pt

Moves forward one square. On its first move only, can go forward two squares. Captures diagonally forward, never straight ahead. The slowest piece — but if it reaches the far end of the board, it promotes into a stronger piece (almost always a Queen).

movecapture
Tap the to highlight its moves
Knight×2 · 3 pts

The only piece that jumps over others. Moves in an L-shape: two squares one direction, then one square perpendicular. Eight possible destinations from an open square. Tricky for beginners and dangerous because it can attack pieces that don't see it coming.

move
Tap the to see the 8 L-shapes
Bishop×2 · 3 pts

Slides any number of squares diagonally. Each bishop is permanently locked to one color of square (one light-squared, one dark-squared). Strong on open boards with long diagonals.

move
Tap the to see its diagonals
Rook×2 · 5 pts

Slides any number of squares horizontally or vertically — never diagonally. Loves open files and the back rank. Often the most powerful piece in the late game.

move
Tap the to see the lines
Queen×1 · 9 pts

The most powerful piece. Combines rook and bishop — slides any number of squares horizontally, vertically, or diagonally. Don't bring her out too early in standard chess — but in Chesstalt, every piece is in play from move one.

move
Tap the to see all 8 directions
King×1 · 0 pts

Moves one square in any direction. Slow, but you must protect him at all costs — losing your king is losing the game. Cannot move into a square where he'd be captured.

move
Tap the to see its 8 squares
Point values aren't part of the rules — they're a guideline players use to decide whether trades are good. Trading a rook (5) for a knight (3) is generally bad. Trading a queen (9) for a checkmate is always great.

Capturing

When your piece moves onto a square holding an enemy piece, that piece is captured — removed from the board permanently. Your piece takes its place. Capturing is the same move as moving; you don't get a free turn for it.

Pawns are the only piece that captures differently from how they move: forward to move, diagonally forward to capture. Every other piece captures along its normal movement pattern.

You cannot capture your own pieces, and you can't move through your own pieces (except the knight, which jumps).

Bishop captures

The bishop slides until it hits something. If that something is an enemy, it can capture.

movecapture
The is an enemy rook — bishop can capture it
Pawn captures

Pawns are different. They move forward but capture only on the diagonals. The pawn directly in front is blocking — not capturable.

movecapture
Notice: pawn can capture diagonals but not the pawn straight ahead

Special Moves

Castling

A one-time-per-game move that lets the King and a Rook switch sides. The King moves two squares toward a Rook; the Rook hops over to the King's other side. Used to get the King to safety and bring the Rook into play.

In Chesstalt: available in Conquest (full classical setup) and for the Solo player in Siege. Not available in Duel or Brawl — kings start too close to the action for castling to be relevant.

En Passant

A rare pawn capture: if an enemy pawn moves two squares from its starting position and lands beside one of yours, you can capture it on the next turn as if it had only moved one square.

In Chesstalt: active in Conquest and for the Solo player in Siege. Not available in Duel or Brawl — pawns there start too close to make double-pushes.

Promotion

When a pawn reaches the opposite end of the board, it must promote — become a Queen, Rook, Bishop, or Knight (your choice). Almost everyone picks Queen. Promotion is active in every Chesstalt mode.

Check & Checkmate

Check is when your king is under attack — an enemy piece could capture him next turn if you do nothing. You must respond by either moving the king out of attack, blocking with another piece, or capturing the attacker. You cannot ignore check.

Checkmate is check with no legal escape. The king is attacked, can't move to safety, can't be blocked, and the attacker can't be captured. Checkmate ends the game instantly — the player whose king is mated loses, no matter how many pieces are left.

Recognizing checkmate: Look at every square the king could move to. If all of them are attacked, and you can't block or capture the threat, it's mate. Mate patterns repeat — you'll start seeing them after a few games.

Three patterns worth recognizing

  • Back-rank mate — a rook or queen lands on the king's back rank, and the king's own pawns block its escape squares.
  • Smothered mate — a knight delivers check while the king is hemmed in by its own pieces with nowhere to run.
  • Two-rook ladder — two rooks alternate driving the king up the board until it runs out of squares.
Back-Rank Mate

Black attacks; White can't escape
Smothered Mate
Knight delivers — king has no air
White checks; Black king blocked by own pieces
Two-Rook Ladder
Rooks coordinate to corner the king
One rook checks, the other guards escape

Draws

Some games end with no winner. The most common ways:

  • Stalemate — your turn, your king is not in check, but you have no legal move. In standard chess this is a draw. In Chesstalt it's not — the player with more piece points wins instead.
  • Threefold repetition — the exact same position occurs three times. Either player can claim a draw.
  • Fifty-move rule — fifty moves pass with no captures and no pawn moves. Either player can claim a draw.
  • Insufficient material — neither side has enough pieces left to force checkmate (e.g., king vs. king).
  • Agreement — both players agree to call it a draw.
Stalemate Position
Black king (amber) is not in check — but has no legal move. Standard chess: draw. Chesstalt: White wins on points.

A Few Chess Tips Before You Move On

You don't need to be a strategist to start playing — but a handful of ideas will save you from the most common beginner traps.

  • Control the center. The four central squares (d4, e4, d5, e5 in standard chess) are where pieces have the most influence. Pawns and knights aimed at the center early give you more options later.
  • Develop your pieces. Don't move the same piece twice in the opening unless you have to. Get knights and bishops out before pushing too many pawns.
  • King safety. A king in the open is a dead king. In standard chess this means castling early. Conquest mode and Siege's Solo player can castle normally; in Duel and Brawl you can't, so kings stay vulnerable — fight tactically and don't let attacks build up around your king.
  • Don't hang pieces. Before any move, check what attacks your destination square. Walking a queen into a defended square is the fastest way to lose.
  • Trade when ahead. If you're up material, trading pieces (even-value swaps) makes the win easier. If you're down material, avoid trades.
One trap to know: the Scholar's Mate. White brings out the queen and bishop early, threatening checkmate on f7 in four moves. It's only deadly if you don't see it coming. If your opponent's queen suddenly stares at your kingside, look for the f-pawn threat.

What Makes Chesstalt Different

If you know chess, the easiest way to think about Chesstalt is: chess, but compressed and aggressive. The fundamentals stay the same — pieces move the same way, checkmate still wins, point values still apply. But Chesstalt layers on a few mechanics that change how every game feels.

  • Per-turn timer. You have a fixed number of seconds per move. Run out, you lose.
  • Banked moves. Sacrifice pieces to earn extra moves — one immediate, plus banked moves that automatically pay out at +1 per turn (Chaos leagues only).
  • Trade. Sell pieces into a points pool and buy different pieces of equal value mid-game.
  • Lone King win. Reduce your opponent to nothing but their king and you win automatically — no need to chase down a checkmate.
  • Four modes. Duel (1v1, narrow board), Brawl (2v2, full board), Siege (1 vs 2), Conquest (1v1, full board with classical setup).

The next sections walk through each mechanic in turn. None of them are complicated on their own — they just stack into a different game.

The Boards

Chesstalt uses two board sizes depending on the mode.

The 4×8 (Duel)

The signature Chesstalt board. Take a standard chessboard, remove columns a, b, g, and h, and you're left with a four-column-wide battlefield on files c through f. The eight ranks remain. The result: every piece is in attacking range from move one. There's no flanking, no slow positioning — just the front line.

Starting position (Black perspective, ranks 8 → 5):

  • Rank 8: Bishop · Queen · King · Bishop
  • Rank 7: Rook · _ · _ · Rook
  • Rank 6: Knight · _ · _ · Knight
  • Rank 5: Pawn · Pawn · Pawn · Pawn

White mirrors the layout on ranks 1–4. Every piece is on the board from move one — no opening phase.

The 8×8 (Brawl, Siege, Conquest)

The full chessboard. Used for the team modes (Brawl, Siege) and for Conquest, which keeps the classical 8×8 piece layout you'd see in standard chess.

The Turn Timer

Every Chesstalt game runs on a per-turn timer — not a clock that drains across the whole game like classical chess. Each move resets the timer. If you run out of time on your turn, you lose immediately. No grace period, no increment.

Each mode has two league variants, each with its own time control:

League variantTime per turnWhat's different
Chaos60 secondsFull Chesstalt rules — sacrifice, trade, banked moves all active. Longer timer to handle the extra decisions.
Classic30 secondsPure chess on the same board, no Chesstalt mechanics. Tighter timer because there's less to think about.

Four modes × two league variants = eight playable leagues total. Bullet/Blitz/Rapid-style time controls aren't separate leagues here — Chaos and Classic are the time controls.

Tip: the timer makes timeouts a real win condition. If your opponent is overthinking, sometimes the right move is the fast one — even if it's not the best one.

Banked Moves

This is the mechanic that makes Chesstalt feel different from chess. You can sacrifice your own pieces to earn extra moves — both this turn and banked for future turns.

Available in Chaos league variants only. Classic variants of every mode play without sacrifice or banked moves.

How it works

When you click the Sacrifice button on your turn and pick a piece, that piece is removed from the board. In exchange, you get bonus moves based on what you sacrificed:

SacrificeImmediate bonusBanked for later
♙ Pawn+1 move now
♘ Knight+1 move now+1 banked
♗ Bishop+1 move now+1 banked
♖ Rook+1 move now+2 banked
♕ Queen+1 move now+3 banked

The "+1 move now" is on top of your normal turn. So sacrificing a pawn means: make your normal move, then make one extra move with another piece. Sacrificing a queen gives you that same extra move plus three banked moves — your next three turns will each automatically get +1 bonus move from the bank until it's empty. You don't choose when to spend banked moves; they pay out one per turn until the bank runs dry.

Limits

  • You cannot sacrifice your king.
  • Banked moves cap at 3 per player. Past that, additional banked moves are lost.
  • Bonus moves this turn cap at 2. If your bank is paying out a +1 and you sacrifice on the same turn, the immediate bonus stacks to +2 (a 3-move turn) — but no further.
  • Sacrifice and Trade share a per-turn lock — once you've used either, the other locks for the rest of that turn.
Try It — Sacrifice a Piece
Turn 1
Bonus moves this turn +0
Banked (max 3)
Tap a piece to sacrifice it. Then advance turns to see the bank pay out.
Strategic feel: sacrificing a queen is enormous — three banked moves means three future turns where you effectively move twice. Pawn sacrifices are about tempo: give up a pawn now, gain a free attack this turn. Knights and bishops are the all-purpose option. Rooks are the heavy investment.

Sacrifice — When It's Worth It

Sacrifice isn't free — you're giving up a piece for moves. The math only works when those moves let you do something a normal turn couldn't. Like Banked Moves, Sacrifice is a Chaos-league-only mechanic.

  • Open lines. A pawn blocking your bishop's diagonal? Sacrifice the pawn to open the line and use the bonus move to swing the bishop in.
  • Set up a checkmate. One more move per turn means you can attack and defend in a single turn — devastating against an unprepared opponent.
  • Fill the bank early. Sacrificing a rook or queen early fills the bank for several turns of move-superiority during its payout window — but it's risky. If your remaining pieces can't hold while the bank pays out, you've given up material for nothing.
  • Save a stuck piece. If a piece is trapped or about to be captured anyway, sometimes you may as well sacrifice it for the bonus instead of losing it to a normal capture.

Trade — The Marketplace

The other way to reshape your army during a game. The Trade button lets you sell pieces into a points pool and buy different pieces of equal or lesser total value, with leftover points returned as change in the form of smaller pieces.

Available in Chaos league variants only. Classic variants don't have Trade.

How it works

  • Click Trade and select pieces from your half of the board to sell. Their point values add up into a pool. The king cannot be sold.
  • Pick what you want to buy. Buy-value can match or be less than your pool — never more. Any leftover points come back as change in pieces (the system breaks it down automatically into the largest pieces that fit).
  • Confirm. The new pieces enter immediately on this same turn via a placement step where you pick where each one lands. Newly-placed pieces are frozen for the rest of this turn — they can't move yet. Your normal move comes from your pre-existing pieces.
  • Trade locks the Sacrifice button for the rest of the turn (and vice versa). You can do one or the other, not both.

What it's good for

  • Three pawns for a knight. Three pawns (3 pts) = one knight (3 pts). Convert raw material into mobility, no change.
  • Cash out a queen. Sell a queen (9 pts), buy a rook (5 pts). The 4 leftover points come back as 1 bishop + 1 pawn. You started with 1 piece and end with 3 — placed wherever you want on your half.
  • Demote a stranded rook. Sell a rook (5 pts), buy a knight (3 pts). The 2 leftover points come back as 2 pawns. The trapped rook turns into mobile material in active squares.
  • Reshape after losses. Down to a queen and pawns? Sell the queen (9 pts), buy 2 knights and 1 bishop (3+3+3=9 pts). Three minor pieces for one queen, all placed where you need them.
The change rule: change is allocated automatically in the largest possible pieces — Q→R→B→N→P. So 8 points of change becomes 1 R + 1 B (5+3), not 2 N + 2 P. You don't pick the change pieces; the system gives you the densest packaging.

How You Win

Chesstalt has more ways to win than standard chess. Any of these ends the game instantly in your favor:

  • Checkmate — same as chess. Enemy king in check with no legal escape. Instant win regardless of piece counts or remaining time. Active in all modes and leagues.
  • Timeout — your opponent's per-turn timer hits zero. Their loss, even if they have a winning position. Don't run out of time. Active in all modes and leagues.
  • Lone King — your opponent has no pieces left except their king (or kings, in 2v2 modes). You win immediately. Active in all modes and leagues, though it rarely happens in Classic since there's no sacrifice/trade to feed it.
  • Stalemate / no legal moves → points — if a player has no legal move and isn't in check, the game ends. Whoever has more piece points wins; equal totals are a draw. (Unlike standard chess, where stalemate is always a draw.) Active in all modes and leagues.

♙ Pawn1
♔ King0 (cannot be lost)

Lone King & Lone King Redemption

The Lone King win

If you reduce your opponent to nothing but their king (or kings, in 2v2 modes), you win automatically — no need to chase down a formal checkmate. This exists because forcing checkmate against a bare king can take dozens of moves and isn't fun for either side. Strip the army, take the game.

This rule applies in every mode and every league variant, Chaos and Classic alike. In Chaos, players reach lone-king positions quickly through trades and sacrifices; in Classic it's rare (no sac/trade to feed it), but the rule is still active if it ever happens.

Lone King Redemption

The flip side: if a trade would leave you with only your king (you sold all your other non-king pieces), the system flags it as a Redemption — you place your bought pieces immediately and your turn proceeds normally with your king's move. This protects players who go all-in on a desperate trade. Only available in Chaos variants since trade itself is Chaos-only.

👑 Lone King — Redemption! This message means you cashed out everything for a fresh army and got to deploy it on the spot.
Lone King — Auto-Win
Black has only their king. White wins automatically — no checkmate needed.

The Four Modes

Each mode plays differently. The core rules (banked moves, trade, lone king, win conditions) stay the same — what changes is the board, the team structure, and the pacing.

The starting positions side by side — different shapes, different setups, same Chesstalt mechanics layered on top.

Brawl
2v2 · 8×8 · two halves
Siege
2v1 · 8×8 · classical
Conquest
1v1 · 8×8 · classical
Duel1v1 · 4×8

The signature Chesstalt format. Two players, narrow board, every piece deployed from move one. Combat is immediate and tactical — there's nowhere to hide on a four-column board. Win by checkmate, lone king, or opponent timeout; stalemate decides on points. No castling or en passant in Duel — the board is too compressed.

Best for: learning Chesstalt's pace. The smaller board makes consequences obvious — in Chaos variant you'll see exactly how banked moves and sacrifices reshape a game.

Brawl2v2 · 8×8

Two players per team on a full 8×8 board, each side deployed in two Chesstalt halves stitched together. Each player controls their own pieces, but pieces move freely across the entire board. Turn order rotates: White P1 → Black P1 → White P2 → Black P2 → repeat. Win by capturing both enemy kings (or reducing the enemy team to only kings). No castling or en passant.

Coordination matters. Your teammate's pieces can defend yours and vice versa. In Chaos variant, a well-timed sacrifice from one player to set up the other's attack is the heart of Brawl. Each player's Sacrifice and Trade only operate on their own pieces and their own half of the board.

Siege2v1 · 8×8

One player versus two — and asymmetric by design. The Solo plays a classical chess setup (top of the board); the Team plays two Chesstalt halves at the bottom. To balance the numbers, the Solo gets two moves per cycle while each Team player gets one. Cycle order: Solo move 1 → Solo move 2 → Team P1 → Team P2 → repeat.

The Solo also gets castling and en passant (their classical setup supports both); the Team does not. Either side can use Sacrifice and Trade in Chaos variants — the Solo on their classical pieces, each Team player on their own half.

  • Solo wins when both Team players are eliminated (each via king-capture or being reduced to lone king on their own pieces).
  • Team wins when the Solo's king is captured or the Solo is reduced to lone king.

Asymmetric by design. Either side can win, neither is "easier." The Solo plays fast and efficient; the Team plays coordinated.

Standard chess piece deployment on the full 8×8 board, with the Chesstalt per-turn timer (and Chaos mechanics in the Chaos variant) layered on. Familiar opening theory works. Castling and en passant are active — Conquest is the only 1v1 mode where both work.

The traditionalist's mode. Classic variant gives you pure chess on the timer (no sac/trade/banked); Chaos variant adds the full Chesstalt layer to a familiar setup.

Where to start: if you're new to Chesstalt, start with Duel. The narrow board forces you to engage with the core mechanics quickly. Once you're comfortable, branch out.

FAQ — Edge Cases

What happens if I disconnect mid-game?

Online only — if you reconnect within the timeout window, the game resumes from the same state. If you don't make it back, you forfeit and your opponent wins. Local games against AI don't have a disconnect concept.

What's a forfeit?

You can forfeit at any time — you lose, opponent wins, treated the same as a regular loss. Online 2v2 and Siege: forfeiting requires your teammate to agree (unless they're an AI, in which case the forfeit is immediate). 1v1 online and any local AI game forfeits instantly.

Can I rematch after a game?

Yes, in any mode and against any opponent. After a game ends, both sides see a rematch button. If both vote yes, a new game starts immediately with the same setup.

Why didn't my sacrifice button work?

Several possibilities: you've already used Sacrifice this turn, you've used Trade this turn (they share a per-turn lock), or you tried to sacrifice your king (not allowed). The Sacrifice button is also not available at all in Classic league variants — it only appears in Chaos variants. If your bonus moves are already at the +2 cap for this turn, sacrificing wouldn't add anything either.

My banked moves disappeared after a sacrifice — why?

Banked moves cap at 3 per player. If you already had 3 banked and sacrificed a queen (which would add 3 more), the overflow is lost. The bank pays out at +1 per turn automatically, so let it drain a turn or two before stacking more.

Why are my newly-traded pieces frozen this turn?

By design. When you trade, the bought pieces are placed immediately on this turn but can't move yet — your normal move comes from your pre-existing pieces. The newly-placed pieces unlock next turn. (Lone King Redemption is the one exception: if trade leaves you with only your king, the rules are the same but practically your only move is the king's, since that's the only un-frozen piece you have.)

Can I castle? What about en passant?

Both are mode-dependent. Conquest uses full classical chess rules — castling and en passant work normally. Siege's Solo player (the classical setup at the top) can also castle and en passant; the Team players cannot. Duel and Brawl have neither — the compressed starting positions make them mechanically irrelevant. Promotion is active in every mode.

Where do I go from here?

Hit Play Now from the home page, pick a mode, and play your first game. Duel Chaos is the recommended starting point — the narrow board forces engagement with the core mechanics fast. Watch your timer, sacrifice a pawn or two early to feel out the banked-move system, and don't worry about losing — you learn fastest by playing.
