If you wrote the wrong example on the teacher’s board or your classroom friends drew the whole board and you are on duty in the class today, then you definitely know how hard it is to wash a blackboard with a wet sponge. Install the game and the sponge will erase the board itself, but here it will need your help in getting around obstacles. Get unbelievable satisfaction from cleaning the board in the game by simply pressing the screen and dodging foreign objects with a sponge.
