    About checkers.gripe

    How do I play?

    Tap or click one of your pieces, then the square to move it to, or drag it there. With the keyboard, move around the board with the arrow keys and press Enter or Space to pick up and put down. If you can capture, you must, and the pieces that can are ringed. In a multi-jump, tap the final square, or each landing square in turn when there's more than one way. Shortcuts: U undo, R redo, H hint, F flip, N new game.

    Which rules does it use?

    American checkers (English draughts) by default: an 8×8 board, Black moves first, men move and capture forward only, kings move one square in any direction, and captures are compulsory, though you choose which. The other games are in the Game menu: International draughts on a 10×10 board, Russian, Brazilian, Pool checkers, Italian and Giveaway, where you try to lose all your pieces. Each has its own rules page below.

    How strong is the computer?

    Easy looks two moves ahead and now and then plays a random move. Medium looks about six moves ahead. Hard searches as deep as it can in about a second and a half, typically eight to twelve moves ahead. It runs on your device, not on a server.

    What is today's opening?

    Tournament checkers starts games from openings drawn by lot. Today's opening does the same with the date, so everyone gets the same first moves and side today. Random opening draws a new one each game.

    What is PDN?

    Portable Draughts Notation, the standard text format for checkers games. Save a game as .pdn to open it in other draughts software.

    Is anything sent anywhere?

    No. The game and the computer player run in your browser. Settings, statistics and the game in progress are kept in this browser's storage; export, import or delete them under Statistics.
