Kuku Kube - Color Test

Look closer. Spot the odd color, find the different letter, and uncover Hidden Numbers across 60 levels. Race the clock or keep going in Endless mode.

One tiny difference. One more try.

Kuku Kube turns a quick glance into a colorful puzzle. Find the tile that stands out, spot a different letter, or look through patterns to uncover hidden digits. Simple taps, subtle details, and that satisfying moment when you finally see it.

SPOT THE ODD ONE OUT Play Color, Text, or Color & Text. Look carefully as the grid grows and the differences become harder to catch.

DISCOVER HIDDEN NUMBERS Explore 60 levels across six visual styles, from colorful dots and misty mosaics to layered patterns. Read the hidden digits and type your answer. Answers check automatically, and a correct answer takes you straight to the next level with a little celebration.

PICK YOUR PACE Choose a 60-second challenge for a quick burst of play. Prefer to take your time? Classic Endless mode has no countdown: keep going until your first mistake. Hidden Numbers also includes untimed practice and a 60-second sprint.

COME BACK FOR ONE MORE Earn stars in the Hidden Numbers journey, revisit puzzles, and try to beat your personal best. Need a little help? Use a hint to make the next detail easier to spot.
