The idea is to get a match of 3 or more bubbles in the same color touching each other by shooting them upwards.
Once such a match is achieved, those bubbles fall, along with any others attached to them and none other (excluding ones on the very top).
Press either [L] or [J] to change the angle of the shooter, and press [K] to shoot.
The first 3 falling bubbles get 1 point each, every additional falling bubble gets 2 more points.
If the match making bubble ever bounces the table border, each bounce gets 5 more points.
The game has 10 levels, once a level is cleared, a bonus of 100 points will be added to the score.
A base line is placed above the score board, the game is over when a bubble is placed on the base line.
