Spot the Difference Brain Game

Only one is different. Find it, tap it, and instantly face the next challenge. Sharpen your focus, beat your best score, and climb the world rankings. Find the single tile that does not belong—and tap it. That is all it takes. Odd One! is a fast, addictive observation puzzle that is easy to understand but difficult to master.

As your score rises, those differences become increasingly subtle—until you are searching for one tiny detail among 100 tiles.
