Snake
The classic Snake. Arrow keys, WASD, or swipe on touch screens. High score saved locally.
2048
The classic number merger. Push tiles with arrows or WASD; equal numbers combine. Reach 2048 to win. Swipe on touch, best score saved locally.
Tetris
Classic falling-block puzzle with a 7-bag randomiser for fair pieces, a ghost landing preview and hard drop. Arrows to play, buttons on touch.
Minesweeper
Classic Minesweeper with three difficulties (9×9 / 16×16 / 30×16). The first click is always safe; right-click to flag, middle-click to chord. Best times stored locally.
Breakout
Classic Breakout. Drag the paddle with mouse or touch; where the ball lands on the paddle sets its rebound angle. Tougher bricks take two hits; clear the wall to advance a level.
Gomoku
Five in a row wins on a 15x15 board. Five difficulty levels drive an alpha-beta engine with a transposition table and kill-search that blocks and builds open fours; or play a friend on the same screen. Undo any move, get a comment on every stone, and keep a local record.
Xiangqi
Full rules: horse-leg blocking, elephant-eye blocking, cannon screens and the flying-general rule; any move that exposes your own king is illegal. Five levels of opponent, iterative deepening with a transposition table, and a mate-in-one check before the deep search.
Reversi
Othello. Trap a line of the opponent between two of your discs to flip it; when neither side can move, the larger count wins. Two opponents: a random one and a positional one. Preference saved locally.
Sudoku
Three levels, puzzles generated on the spot with a guaranteed unique solution. Pencil notes, conflict highlighting, hints, keyboard input and a timer; best times saved locally.
Game of Life
Conway style cellular automaton. Two rules grow gliders, toads and the Gosper gun that keeps spitting gliders. Paint cells on the canvas, scatter a random soup, adjust the speed.
Lights Out
Pressing a cell flips it and its four neighbours; turn every light off. Four board sizes from 3x3 to 6x6, always solvable. Hints when stuck, best move counts saved locally.
Maze
A perfect maze from recursive backtracking: exactly one path between any two cells. Walk it yourself or let the solver draw the shortest route. Bigger boards or a few braided loops change the feel completely.
Sliding Puzzle
The classic sliding puzzle from 3x3 to 5x5. Shuffles are produced by walking backwards from the solved state, so every deal is solvable. When stuck, the A* solver gives the next move or the whole solution.
Pong
Two paddles, one ball, first to seven. The opponent predicts where the ball lands but misjudges a little on every return — push it to its backhand.
Memory
Flip two cards to find a matching pair. Four sizes from 6 to 12 pairs; moves and accuracy are tracked, and the fewest moves per size are saved locally.
