Two real rule sets, a serious offline computer engine, local two-player play, clocks, free hints, exact game recovery and a daily position — all private in your browser.
American/English Checkers enforces compulsory captures, forward-only man captures, multi-jumps and turn-ending promotion. International Draughts uses a 10×10 board, backward man captures, flying kings and the maximum-capture rule.
Best Move is free. Move Coach compares your choice with the local engine's preferred move. Assisted games are clearly marked so clean records remain meaningful.
The board, engine, saved game, settings and statistics run locally. There are no ads, accounts, subscriptions, trackers or external game libraries in this standalone build.
