Odd One Out: Spot the Tile — Find the one tile that looks different in 15 rounds and beat your best time. Free to play on Google Play, with ads.

About the Game

A grid is full of the same shape, and exactly one tile is different. Find it and tap it as fast as you can. Clear 15 rounds and your total time is your record, so lower is better. It is the focus game from the brain games in FDK Brain Check, now also available as its own app on Google Play.

How to Play

Pick a level on the home screen and tap Start. Easy is a 3×3 grid, Normal is 4×4 and Hard is 5×5
Touch the ready screen to start the clock. The grid stays hidden until you do
The odd tile can differ in shade, shape or size, so you never know which one is coming
A wrong tap adds 2 seconds. After round 15 you get your time and a grade
Pause any time. The grid is hidden while paused

Colors differ only in brightness, so colorblind players get the same challenge
