Odd One Out — Spot the Different Tile
One tile is a slightly different shade. Tap it before time runs out. Each round the grid grows and the difference shrinks.
How to play
- Click Start — a grid of same-colored tiles appears with one slightly different.
- Tap the tile whose shade is different from the rest.
- Each correct tap advances a round; the grid grows and the difference shrinks.
- Wrong taps flash a red outline but don't end the game.
- Score as many rounds as you can before the 45-second timer runs out.
A grid of identical colored tiles hides one impostor that's a slightly different shade. Tap it to advance. With every round the grid gets bigger and the color difference gets smaller, testing your color discrimination and visual search speed against a 45-second clock.
Frequently asked questions
- How does the difficulty increase?
- Each correct tap grows the grid by one row and column and reduces the shade difference, so later rounds are much harder to spot.
- Is this a color blindness test?
- No — it's a visual search game, not a clinical test. People with color vision deficiencies may find later rounds tougher, but it isn't a diagnostic tool.
