About this game

Sharpen your mind like a blade.

Ink Ninja is a fast, beautiful mental-math game painted in the style of Japanese sumi-e ink art. Numbers fly through the air. Slash the correct answer and let the wrong ones fall.

SLICE TO SOLVE
Every swipe is an answer. Addition, subtraction, multiplication, division and mixed chains scale as you improve, so it stays sharp whether you are drilling times tables or chasing your own high score.

TWO WAYS TO PLAY
- Blade Storm: survive a rising tide of problems, build your combo and hold your streak as the pace climbs.
- Quick Draw: one problem, one heartbeat. Answer before the blade falls.

WALK THE LIVING INK
Travel 21 paths across three regions - Bamboo Dawn, Moonlit Crossing and Ember Summit - restoring a painted world one cut at a time. Each region ends with a guardian who tests everything you have learned. Earn up to three stars on every path.

LAND THE MASTER HIT
Clean, fast, precise cuts score higher. Chain them for combo multipliers and watch your score climb. Unlock new blade trails as you go.

LIVING INK ART
Hand-painted watercolour guardians, brush-stroke effects and a calm, uncluttered screen designed to keep your focus on the numbers.
