Memory game that improves your mathematical calculation ability.

The board consists of several fields (depending on the board chosen) and each one of them hides a number. The idea is to open pairs of fields that add up to a random number according to the level selected.

When the two open fields add up to the correct amount, they stay open and change to green. If the sum is not correct, the cells change to red and are closed again. You have to get all the fields of the board left open in the shortest time possible.

The app will help you develop your mind by improving and training your visual memory. The app will also improve your calculation ability as you need to complete summation operations very quickly. If you're constant and play regularly, you'll see that you perform the calculations faster each time.

The game is perfect for everyone, both for the youngest who are developing their memory and calculation skills, and for adults who need to keep those skills active in order to stay mentally fit.
