Twenty games across four categories: strategy board games (Chess, Checkers, Connect 4, Reversi, Mancala, Gomoku, Ultimate Tic-Tac-Toe, Dots and Boxes, Nine Men's Morris, Backgammon, Battleship, Hex), card games (Crazy Eights, Blackjack, Solitaire), puzzles (2048, Minesweeper, Sudoku, daily Word Guess), and arcade (Snake). Browse them all on the homepage.

Each game has its own engine. Connect 4 uses bitboard negamax; Chess, Checkers, Reversi, and Mancala use minimax with alpha-beta pruning; Gomoku uses threat-pattern scoring; Battleship uses probability-density targeting; and so on. On AI Training difficulty the engines search as deep as they can within a strict time limit.

Easy (shallow search with deliberate imperfection — great for learning), Medium (a solid casual challenge), Hard (deep search that punishes mistakes), and AI Training (maximum strength under a time budget — the real test).
