How it works
When a player taps their clock, their time freezes (with the configured increment added) and the opponent's clock starts. If either player runs out of time, the game ends with a "win on time" for the opponent — just like FIDE rules.
Formula
Time control notation: [base minutes]+[increment seconds]. So "5+3" = 5 minutes base + 3 seconds per move.
Key features
