Practice ratings · vs computer, not CSR
Practice ratings from your timed games against the computer, kept on this device only. They are not your CSR (ChesStresS Rating): CSR comes only from rated online games against people and is shown in Profile › Account. Same method as CSR (Glicko-2: ± is the rating deviation, “?” = provisional). Games without a clock and Chess960 are not counted. How CSR and TSR work

Turbo ChesStresS
White team vs Black team. Everyone votes; the most popular move is played. 12 seconds per move. Fall below the team's average agreement minus 5 points and you are out – but you may continue for free, up to 3 times per event.
Demo: your team-mates and opponents are simulated bots of mixed strength. After you vote the round closes early so testing is quick.
Turbo practice is free for everyone: no tokens are charged and no tokens are won. You play for points, your place in the standings and XP.
