Kuku Kube - Color Test

One tiny difference. One more try. Kuku Kube is a colorful observation puzzle game. Tap the tile with the different shade, find the odd letter, or look through patterns to reveal hidden numbers. The rules are simple, but the details get trickier as you play. SPOT THE ODD ONE OUT Choose Color, Text, or Color & Text. Follow the growing grid and see how far your attention takes you. UNCOVER HIDDEN NUMBERS Explore 60 levels across six visual styles. Study each image, enter the digits you see, and move straight to the next puzzle when you get it right. Revisit levels and collect stars along the way. PLAY AT YOUR PACE Try a 60-second run when you want a quick challenge. Prefer no countdown? Endless mode keeps going until your first mistake. Hidden Numbers also has untimed practice and a 60-second sprint. NEED A LITTLE HELP? Hints are limited, so use them when a puzzle has you stumped. Get a daily gift, watch an optional rewarded ad when available, or find extra Hint packs in the Shop. Kuku Kube includes ads and optional in-app purchases, including Remove Ads and Hint packs. It is an entertainment game, not a medical vision test.
