Your task is to remember the positions of all colored squares in the matrix. Once they disappear, mark the positions on which the colored squares were located.

You earn points for each correct position. If you correctly mark all the positions in the round, you will get a bonus.

The difficulty of the game depends on your success. After every successful round, the difficulty increases. On the contrary, after an unsuccessful round (i.e., one in which you place the squares twice incorrectly), the difficulty decreases.
