A two-player chess clock for timed games. Tap to switch between players after each move. Supports standard time controls used in tournament, blitz, and bullet chess.
10 minutes per side (rapid) is good for casual play. For faster games, try 5+0 (blitz) or 3+2 (blitz with 2-second increment).
Increment adds a few seconds to your clock after each move. For example, 5+3 means 5 minutes per side with 3 seconds added after every move.
