Sharpen your mind in this simple, straightforward game! A number will appear in the center square, then you must find the same number in the other 72 squares. At first there will be just one number in the grid, but each time you tap the correct square, more will be added making the difficulty greater and greater. Your goal: finish 100 levels in the fastest time possible.

Challenge your friends and family to top your best score, or play it alone to keep your mind strong and flexible and keep an eye out for future variations on the premise!
