About the 90+30 time control
This is the control behind elite classical chess: ninety minutes for the whole game, with thirty seconds added every move from move one.
It rewards the deepest calculation, preparation and endgame technique, and games can run for hours. Historically many events added extra time after a set number of moves; the single-phase 90+30 is the modern simplification.
In short: 90 minutes per player with 30 second increment, in the classical range. Tap below to start it now, or read more about how the time-control tiers compare.
