Read full description

Numbers fly. You have one blade and sixty seconds. Math Ninja is a fast, beautiful arcade math game painted in traditional Japanese ink. A target appears, numbers are thrown into the air slice the ones that solve the equation, dodge the fakes, and never, ever cut a bomb. TWO WAYS TO PLAY • BLADE STORM - numbers fly like fruit; cut them before they fall • QUICK DRAW - the whole board appears at once; find the answer as fast as you can RISE THROUGH 12 STAGES Start with simple addition and take-away. Earn your way to multiplication, division, and long operator chains only a true Master Ninja can cut. Every stage is a 60-second race against the clock with its own goal to beat. PRECISION IS EVERYTHING One decisive cut is a MASTER HIT worth double. Hesitate, and your blade earns less. Every run is graded S to C same score, different skill, different seal. LEARN IN THE DOJO A gentle, untimed tutorial teaches the way of the blade — no timer, no danger, no reading required. MADE WITH CARE • Hand-painted sumi-e ink art style • Original Japanese-inspired soundtrack • Global leaderboards - the Hall of Blades (Game Center) • No ads. No subscriptions. No data collected. • Pay once to unlock all 12 stages, yours forever Sharpen your mind. Draw your blade. Music by HitsLab, Monument Music and Tunetank. Sound effects by Floraphonic and Universfield.
