Test your eyesight in the simplest concentration game on your phone!

You're faced with a grid of squares, all one color… except for one that's slightly different. Your mission: find it before time runs out!

How to play?

• Tap the square with the different color.

• Each correct answer earns you a point and extra time.

• A wrong answer deducts time, so watch out!

As you progress, the challenge increases: the number of squares grows from 2x2 to 6x6, and the difference between the colors becomes more subtle and harder to spot. How far can you go?

• No annoying ads.

• Small size and simple, eye-friendly design.

• Saves your highest score so you can challenge yourself every time.

• Suitable for all ages.

One minute of waiting or a break is all it takes for a quick round. Can you beat your high score?
