The player tries to burst bubbles with a harpoon that have similar characteristics to balls. When a bubble is hit, the player splits into two smaller bubbles. Depending on the size of the bubble, it can be split a maximum of three times. The last time, the balloon disappears from the playing field.

If the player is touched by a bubble, he loses one life. After the loss of all life, the game is over.

By chance, sharing the bubbles leaves power-ups behind. These allow, for example, shooting with a second harpoon or equipping it with an anchor. In addition to better weapons, the player can also find a shield or items that manipulate the passage of time.
