Move with the mouse on the playing screen and collect the coins of the identical color. Create the tower in this way. Finish the tower by clicking the mouse. Be careful and do not touch the coins of the other colors with the tower, otherwise it will fall down. If you cannot get to a certain coin, finish the tower. If there is a coin of each color left at the end of the game, just click on them and they will disappear. Watch out for the time limit.
Start the game by clicking on PLAY GAME and control it with the mouse.
