One tile is different.

You have four seconds to find it. The hue gap closes as your streak grows.

Best streak: 0
Same saturation. Same brightness.

Only the hue moves.

Guess Hue changes only one tile’s position on the colour wheel while saturation and brightness stay fixed. Warm-up rounds use a generous gap; longer streaks demand finer colour perception.

The rules

Scan the colour grid and select the tile whose hue differs from the rest. A correct choice extends the streak and reduces the colour gap; a miss ends the run.

What makes it different

The four-second limit keeps perception instinctive, while the adaptive hue gap gives every streak a natural difficulty curve.

How to play
