You play as a shark that hunts fish for its supper. Being a greedy shark, you can't afford to leave too much ´ of fish pass... After 3 missed fish, the game is lost. The game is mouse controlled and continues endlessly, or until 3 fish have been missed (whichever comes first).

At the start of the game, the level is displayed for 3 seconds: Level 1. After 3 seconds the text disappears and the first fish appears on the screen. In order to capture the fish, you have to click on the canvas with the mouse to throw balls. Each fish caught raises the score by +1. However, the fish move: if a fish manages to get out of the screen without captured, it is considered lost. After 3 missed fish, the game ends and the game is lost. The score is displayed on the screen and the number of missed fish remaining (initially 3) is represented by images of fish under the score. For every 5 captured fish, the level of the game is increased: the fish stop appearing for 3 seconds and the game displays the next number of level, e.g.: Level 2.
