A simple, clear and at the same time very effective game for developing attention and dexterity. You can of course play it together, but we recommend a single version. Press the space bar for the left half and the up arrow for the right half at the moment when the gray chip is in the center of the trap circle. At the end of the game, you will see which half of your brain is more developed — the left or right. Just look at the result.
