Chess Clock

A free, fast online chess clock — and a straight-talking guide to the time controls behind every game. Pick a format and play.

Bullet

The fastest chess there is — sub-three-minute games where reflexes, pattern recognition and clock speed decide everything.

Blitz

Fast, sharp and addictive — blitz is chess played in minutes, not hours. Here’s what it is, why it exists and how to play it.

Rapid

The sweet spot — enough time to actually think, short enough to finish in a sitting. The best format for improving players.

Classical

The traditional, deepest form — hours per game, where calculation, preparation and endgame technique decide outcomes.
