Mental Math offers solo practice and live races for two players. Score one point for each correct answer during a 120-second round, or customize the duration, operations, number ranges, and scoring. Solo practice runs in your browser; in a race, both players work through the same sequence at their own pace.
Both players ready up before the countdown. The match clock starts together and continues through temporary disconnections.
Type the answer to advance. Automatic submission accepts a correct answer as soon as it is complete; Enter mode waits for you to submit.
The highest score when time expires wins. Equal scores are a draw. Optional mistake and skip penalties are shown in the room settings.
