Odd Cube is a quick colour-vision challenge. A grid of pixel cubes looks identical, but one is a slightly lighter or darker shade. Spot it and tap it before the timer runs out. Each correct find makes the grid bigger and the difference subtler, so your eyes have to get sharper with every round.
Odd Cube is one of the 40 mini games in Pixel Pop Arcade. It runs instantly in your browser on phone, tablet or PC, with no download and no sign-up. It's completely free, it remembers your personal best, and playing earns coins for Pixel Pop Flow, the main game starring our round jelly critters.
