Kuku Kube - Color Test
Spot Colors & Hidden Numbers
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
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 180 levels across 18 chapters and eight visual patterns, from colorful dots and misty mosaics to rings, petals, and 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.
