At the start the game board is filled with 8.
You choose your level (beginner, advanced or expert) and the difficulty from 1 to 50. The computer chooses, at random, the boxes to modify (depending on the difficulty: 1 for 1 box, 50 for 50 boxes!). The chosen square increases by 1 point while its neighbors (up, down, right and left), decrease by 1 point.

You must return to the initial state of the board.

For that you choose a box, this produces the opposite effect of the computer. The difficulty therefore corresponds to the minimum number of moves necessary to find only 8s on your board.

From easy to evil, the choice is yours!
