You have numbers between the walls and you have to move them by the black circles with arrows (rotator) to correct order: for bottom right to bottom left, one up and to the right up left up (to make the numbers in shape like snake (its hard to explain)) And help is: if it emits green light its in correct place if red its in the wrong place The first and the second one is just training the true comes after that :D
This is also a game for a class and two teachers like this game and saying: "its awesome" Btw, the username in the code is just for me like I dont want to make records you know :D
