Quick answer
Three-Player Chess uses a 96-square board and three armies of 16 pieces. Turns rotate among the players still in the game. An eliminated player's pieces stay on the board as frozen blockers that cannot move or be captured; the last active player wins. This guide covers Modern v1 · ChessPlayX three-player variant.

How is the board set up?
The 96-square board has three territories, with sixteen standard chess pieces per player. ChessPlayX's Modern variant defines movement across the centre and player elimination. It is not ordinary two-player chess with an extra opponent.
What is the turn order?
Turn order: White → Black → Red in Three-Player Chess; Wei → Shu → Wu in Three Kingdoms Xiangqi. Each player competes independently.
How do pieces cross the centre?
The 96 cells form three sectors. Diagonals can fork at the centre; select a piece to see every legal route. Knights jump along the board's connections.
How do pawns move and promote?
Pawns advance into either enemy sector and promote on an enemy back rank to queen, rook, bishop or knight. Castling requires unmoved king and rook, a clear route and safe king squares. En passant lasts through each opponent's next turn.
When is check resolved?
Both opponents can give check. You must leave your own king or general safe. Royals are never captured; checkmate is decided when the checked player's turn begins.
What happens when a player is eliminated?
Mate, resignation or timeout eliminates one player. Their army stays as frozen, uncapturable blockers. The last active player wins; disconnection alone does not immediately eliminate anyone.
When is the game drawn?
Threefold repetition, or 150 consecutive moves by all players without a capture or pawn/soldier move, draws the game. A player who is not in check but has no legal move: in Three-Player Chess, that turn is skipped while three players remain and the game is drawn when two remain; in Three Kingdoms Xiangqi, that player is eliminated. Historical Three Kingdoms special pieces and army transfer are not used.
How to play on this screen
On desktop
Click your army’s piece, inspect the highlighted routes, then click a legal destination. Follow the board’s connections through the centre instead of extending an ordinary square-board line. “Rotate view” changes only your view; use the zoom control to inspect crowded intersections.
On a phone
Tap a piece and its highlighted destination. Pinch to zoom, or use the zoom button; drag the enlarged board to inspect the centre, and use “Rotate view” to change perspective. The sliders button opens “Moves & game options” or “Moves & Chat”, depending on the room. Close that panel to continue on the board.
What should beginners watch for?
Before moving, inspect threats from both opponents. A piece left by an eliminated player still blocks routes, so do not plan as if that territory were empty.
