Chess

Chess is the classic game with nothing in the way: no downloads, no sign-up
for local play, no clutter. Open it and make a move.

Three ways to play. Challenge the computer at Easy, Medium, or Hard —
Easy is friendly to beginners, Hard will punish a careless middlegame. Hand
the device to a friend for pass & play. Or create a private online game and
invite a friend with a code or link; when they tap Join, you're playing —
complete with resign and rematch.

Real chess, every rule. Castling, en passant, promotion, checkmate,
stalemate, threefold repetition, the fifty-move rule, and insufficient
material are all enforced by a hand-written engine validated against
reference test positions. Move by click, tap, or drag — with legal-move
hints, last-move and check highlights, and smooth animation.

Chess clocks that play fair. Pick Bullet, Blitz, or Rapid time controls
(1+0 up to 15+10, with Fischer increments) or play with no clock at all. The
clock starts with the first move, so an untouched board never costs a second,
and time is charged from real timestamps — a backgrounded tab can't cheat
anyone. Run out of time and you lose, unless your opponent can't possibly
mate: that's a draw, exactly as the FIDE rules say.

Your game survives anything. A game against the computer or in pass &
play is saved as you play. Close the tab, reload, put your phone away — the
board, the move list, the captured pieces, and both clocks pick up right
where you left off.

Review and export. Step back through the game with the on-screen controls
or the arrow keys, click any move to jump to that position, and copy or
download the whole game as a PGN file that any chess app can read.

At home on any screen. A responsive layout that works from a phone to a
desktop monitor, with light, dark, and follow-system themes. Moves are shown
in standard algebraic notation alongside captured pieces and the material
count.

Free to play, and local games never leave your device.
