How It Works

The shooting game starts when you touch "START" button in webpage. With everything set, the count down starts on the webpage, and the game runs for 30 seconds. When you shoot down the targets with electric gun, you receive 5 points for the target on the left, 10 points for the target on the right each time. When the game is over, you can check your score.
