How to use
- Pick a mode before the first move: vs AI (Easy) uses a depth-2 minimax search and plays a random move 30% of the time, vs AI (Med) uses depth-3 with full evaluation, and vs AI (Hard) uses depth-4 alpha-beta pruning for stronger positional play. Press New Game to set the standard starting position; White always moves first per FIDE rules.
- Click any of your pieces to highlight every legal destination. The engine filters out moves that would expose your own king to check, so pinned pieces and blocked sliders only show genuine options — a fast way to learn how knights jump, bishops cut diagonals, and rooks command files.
- Click a highlighted square to move. Special moves are handled automatically: castling (click the king then the square two files away — kingside or queenside, neither the king nor the chosen rook may have moved, no squares between can be attacked, and the king cannot be in check), en passant (click your pawn diagonally onto the square a just-moved opposing pawn skipped over — only legal on the immediately following move), and pawn promotion (a chooser appears at the back rank for queen, rook, bishop, or knight).
- Watch the captured-pieces panel for the live material count. It uses standard centipawn values — pawn = 1, knight = 3, bishop = 3, rook = 5, queen = 9, king = priceless — and shows the material differential. A two-pawn advantage in the endgame is usually winning; a minor piece up (knight or bishop) is decisive at every level.
- Use the Undo button to take back the last move (your move and the AI's response). This is essential for learning — try a tactical idea, see the engine refute it, then back up and find a better continuation. Hitting Undo doesn't count as a loss in your stats.
- Win by delivering checkmate: the opposing king is in check with no legal escape (no square moves out of attack, no piece can block, and no piece can capture the checking attacker). The game also auto-detects draws by stalemate (the side to move has no legal moves but is not in check), insufficient material (e.g. K vs K, K+B vs K), and threefold repetition.
- Beginner opening rule of thumb: control the center with 1.e4 or 1.d4, develop knights before bishops, develop bishops before queens, castle within the first 10 moves, and don't move the same piece twice in the opening unless you must. The Italian Game (1.e4 e5 2.Nf3 Nc6 3.Bc4) and Queen's Gambit (1.d4 d5 2.c4) are the two most beginner-friendly openings.
Frequently asked questions
How do I play chess online for free?
Open this page and start playing immediately — no account or download needed. Click any piece to see its legal moves highlighted, then click a destination square. The game enforces all standard chess rules: castling (both kingside and queenside), en passant captures, pawn promotion with piece selection, check and checkmate detection, and stalemate draws. It is a two-player local game, so you can play with a friend on the same device.
Does this game track captured pieces?
Yes — captured pieces are displayed in a panel alongside the board, separated by color. The game also calculates and shows the current material advantage using standard piece values: a pawn is worth 1 point, knights and bishops 3 points each, rooks 5 points, and the queen 9 points. This lets you quickly assess the balance of power without counting manually. Tracking material advantage is a fundamental skill in chess that helps guide your strategy.
What are the basic chess piece movements?
Each chess piece has unique movement rules. The king moves one square in any direction. The queen moves any number of squares horizontally, vertically, or diagonally. Rooks move any number of squares horizontally or vertically. Bishops move any number of squares diagonally. Knights move in an L-shape (two squares in one direction plus one square perpendicular) and are the only pieces that can jump over others. Pawns move forward one square (or two from their starting position) and capture diagonally. Understanding these movements is the first step to developing chess strategy.
What is castling in chess?
Castling is a special move that lets you move your king two squares toward a rook, and the rook jumps to the other side of the king — all in one turn. It serves two purposes: it moves the king to safety behind a wall of pawns, and it activates the rook by bringing it toward the center. Castling is only legal when neither the king nor the rook has moved, there are no pieces between them, the king is not in check, and the king does not pass through or land on an attacked square. Most strong players aim to castle within the first 10 moves.
What are some good opening strategies for beginners?
The three most important opening principles are: control the center (move pawns to e4/d4 or e5/d5), develop your pieces (get knights and bishops off the back rank early), and castle quickly to protect your king. Avoid moving the same piece twice in the opening, avoid bringing your queen out too early (it becomes a target), and avoid moving too many pawns at the expense of piece development. Classic openings for beginners include the Italian Game (1.e4 e5 2.Nf3 Nc6 3.Bc4) and the London System (1.d4 followed by Bf4 and e3).
What is the difference between checkmate and stalemate?
Checkmate occurs when a king is under attack (in check) and has no legal move to escape — the game ends immediately and the attacking player wins. Stalemate occurs when a player has no legal moves but is not currently in check — this results in a draw, not a win. Stalemate is a common trap for beginners who are winning overwhelmingly but accidentally leave their opponent with no legal moves. Always make sure your opponent has at least one legal move unless you are delivering checkmate.
