The game will help you to train your attention and focus. Get the highest level with some bonus for your brain! Try to get to level 25.
Your goal on each level is to find a specific number (or not a number – there are surprises!) in a very limited time.
Some says there are colored aliens on level 17. Some says there is a red-hat-wearing plumber on level 100. But everybody's agreed that this game requires maximum attention and rapid decisions.
