Reaction Time play online

Press the tile that changes color; as soon as you can. If the result is more than 5 seconds, it will be disgarded.

The app will show you the time used, the best time on the current level, how many times you have played the current level and the average time.

You can choose between 9 different levels (2-10). The number of tiles on each level is the square of the level number (4-100).

Have fun!
