Your task is to prevent the balls from falling over the border. You will have to come up with a strategy to evenly connect the coins. Do not leave smaller coins at the very bottom, as it will be difficult to connect them!
A new coin appears at the click location. Connect coins of the same denomination to get coins of a larger denomination. There is a bomb button in the lower left corner. You can select it and click on the field, so it will destroy several balls in a certain radius.
