One square doesn't match. Tap it. The grid grows and the colors get closer every round.

Spot the odd one out

You have 60 seconds. Every right answer scores a point. Every wrong tap costs 3 seconds.

How it works: the grid goes from 2×2 up to 8×8, and the odd square's color gets closer to the rest as your score climbs. Most people tap out somewhere in the 20s.
