Flash Mind Booster is a small and easy puzzle.

You need to be fully concentrated.

The aim of the game is to look at a number for a short time and try to remember it.

After that you have to type it again.

After you have given three successive correct answers, the number grows, which increases the level of difficulty of the game.

If you give a wrong answer, the number diminishes. You can alter the time during which the number is shown on the screen, as well as the initial level of difficulty (the number of digits).

This short and funny game will improve your concentration and visual memory.
