TapDoku: Daily Color Puzzle

TapDoku is a daily color perception puzzle. Each grid hides one tile in a slightly different shade — find it before the timer runs out. Simple to learn, hard to put down.

A NEW PUZZLE EVERY DAY
Everyone gets the same daily challenge, generated fresh each day. Race the 60-second clock, solve as many grids as you can, and build a daily streak. Miss a day and the streak resets — so keep coming back.

TWO WAYS TO PLAY
- Daily Challenge — a 60-second sprint with 3 lives. Same puzzle for everyone, every day. Compare your score and protect your streak.
- Endless Mode — pure, calm color hunting. One grid at a time, faster and faster. One wrong tap ends the run. How far can you go?

TRAIN YOUR COLOR VISION
Tapdoku is a real test of color perception and reaction time. The grids grow and the shades get closer together as you improve. Track your average reaction time and watch your accuracy climb week after week.

CLEAN, MODERN DESIGN
