The game currently has eight sub-games (more sub-games are coming soon) described below. Level 1,000 is not the end of each sub-game. You can play them infinitely beyond 1,000. Purchase once, enjoy the current and all the upcoming games. 1. Angle: Which is larger? Select a larger angle between two given angles. Improve your sixth sense for measuring angles. 2. Area: Which is larger? Given objects are rectangles, ellipses, or triangles. Improve your sixth sense for measuring area. 3. Calculate: Which is greater?

Improve your sixth sense for distinguishing similar colors. 5. Count: Which has more circles? Improve your sixth sense for counting objects at a glance. 6.

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.
