8 × 7. 93 − 47. 144 ÷ 12. How fast can you answer?
CalcBlitz turns mental math into a fast, addictive game. Problems pop up. You tap in the answer. One mistake ends your streak-or time runs out.
TWO GAME MODES
CLASSIC MODE
Build the longest streak you can. Every correct answer keeps you going. One wrong answer ends the round. How far can you get before you slip up?
BLITZ MODE
You have 60 seconds. Solve as many problems as you can. Wrong answers don't end the game-but they cost points. Race the clock and beat your high score.

• Difficulty increases with your streak-stays challenging
