The purpose of this game is to shoot the targets and earn money.
In each round you are presented with several targets. Shoot a target and it will go flying in the air, shoot it again until it explodes. If the target falls off stage the game is over. There are 10 rounds total, with different targets. Each target gives you 100$ bonus for each shot and a 500$ bonus when exploding, however, you can multiply your score by "balancing" more than one target at the same time. It is very difficult to balance more than 3 bottles, but there is a bonus target ("star bottle") to help you. If you destroy the star bottle you slow down the game for a short time, thus making it much easier for you to shoot all the targets.
Have fun!
