This is American checkers (no diagonal-only "flying kings," standard forced captures) rendered as a 3D tabletop with three bot difficulty levels. Unlike the tic-tac-toe game on this site, the bot here runs a real minimax search with alpha-beta pruning — it looks several moves ahead and evaluates board positions rather than following fixed rules, so higher difficulty genuinely searches deeper, not just plays "meaner."
Captures are mandatory, matching standard American rules: if a jump is available, you must take it, and the game will tell you so rather than let you make a quieter move. A game is called a draw after 40 moves pass without a single capture, which mirrors real tournament stalemate rules.
Sound effects are generated procedurally with the WebAudio API rather than audio files, so there's nothing to download beyond the page itself — pick a difficulty and the board is ready instantly.
