Free daily mental arithmetic games
Four games that put arithmetic under a clock. Blitz is twenty problems, fifteen seconds each, one wrong answer ends the run. Blitzed is the same ladder with three numbers on every line. Crunch gives you six numbers and a three-digit target. Calc is a keypad whose buttons alternate number and operator, so the route you walk is the sum.
Blitz and Blitzed are sprints and are the only timed games in the family. Crunch is the television numbers game: add, subtract, multiply and divide six numbers to hit the target exactly, scored on steps. Calc is a path puzzle: start on the first key, end on the last, and the keys you pass through have to compute to the target.
Blitz and Blitzed are. Crunch and Calc are scored on accuracy and steps, with the clock as the tiebreak.
All four, every day, no account required.
