Sleepchess: replay chess games slowly to fall asleep

Adds a Sleep replay button to finished games on lichess and chess.com: watch them replay slowly, with soft piece sounds.

Sleepchess turns chess games into something to fall asleep to. On lichess.org and chess.com, a small "Sleep replay" button appears in the corner of every finished game. Tap it, and the game opens on Sleepchess, where it replays slowly from the first move, with soft piece sounds, a dim board and a sleep timer. No analysis, no evaluation bar, no excitement: just the quiet rhythm of a game you know, move by move. You can also paste any game in PGN from the toolbar button: a classic you love, or one of your own. • Works on finished games only. It never touches a game that is still being played. • Collects no data and has no server of its own. It only asks the site you are on for the moves of the game on screen. • Free, no account, no ads. Sleepchess is a free website (sleepchess.com) that also replays classic chess, xiangqi and Go games at bedtime.
