    Shatranj was born in India, and it's still one of the best ways to sharpen your mind. Play a full game ofchess against the computer on four levels — from a forgiving Beginner to a Hard opponent that calculates several moves ahead — or pass the phone to a friend for a two-player game. Legal moves are highlighted, every rule is enforced (castling, en passant, promotion, stalemate and draws), and your game is saved automatically.

    How to play

    1. Choose the computer or 2 players, a level and your colour, then tap New game.
    2. Tap one of your pieces to see its moves, then tap a highlighted square.
    3. Checkmate the opponent's king — attack it so it has no escape — to win.

    Tips for beginners

    • Control the centre with pawns and pieces in the first few moves.
    • Develop knights and bishops before moving the queen out.
    • Castle early to keep your king safe.
    • Before every move, check: what does my opponent threaten, and is my piece protected?

    Example

    The quickest checkmate is “Fool's Mate”: 1. f3 e5 2. g4 Qh4# — White weakened the king's diagonal and Black's queen delivered mate in two moves. Try it against a friend in 2-player mode, then learn to defend against it. For quicker games, play tic-tac-toe or train your brain with memory match.

    Frequently asked questions

    How do I move a piece?
    Tap a piece to select it — its legal moves are marked with dots — then tap the square you want to move to. Tap the piece again (or another of your pieces) to change your mind. When a pawn reaches the last rank you choose what it becomes.
    How strong is the computer?
    Beginner makes casual mistakes and suits new players. Easy looks two moves ahead, Medium three, and Hard searches deeper for up to a few seconds per move — a good challenge for club-level players, though not a grandmaster engine.
    Does it follow all the rules?
    Yes: castling, en passant, promotion, check, checkmate and stalemate, plus draws by the fifty-move rule, threefold repetition and insufficient material.
    Can I undo a move or play as Black?
    Yes. Undo takes back your last move (and the computer’s reply). Choose Black before starting a new game and the board flips so your pieces are at the bottom.
    Is my game saved?
    Your current game is saved on this device, so you can close the page and continue later.
