Can you count to ten? Prove it!

The Arithmetis puzzle game allows everyone to work mental arithmetic and youngers review the additions and subtractions.

Of increasing difficulty, the first levels are widely accessible to children while offering challenges for adults. The last few levels are the ones more difficult to complete.

The goal is to finish all 10 levels, writing the correct operations in the grid with numbers and operators available. Any complete operation disappears from the grid to make room for the following.

Each level takes place in 2 stages: the first is to write a number of correct operations in the grid (this number increasing over the levels); the second step is to complete all started operations to empty the grid.

Beware, numbers available evolve during levels. The first level provides only 0 and 1, the second 0, 1, 2, up to the 10th level which provides the numbers 0 to 10.

You can get coins that will help you advance through the levels:
- A coin allows you to move the last placed token,
- A coin lets you exchange one token with another token of your choice (from the same family: operator or number).

Beware, the use of those coins is limited in the game. Starting the game, you do not have the ability to use coins. At the end of each level, you get one coin usable later in the game (if your stock of coins permitting of course).
