The aim of the game is to score points by popping bubbles with the mouse.
You can only pop bubbles where two or more of the same colour are next to each other.
The more bubbles of the same colour together, the higher the points for popping them.
The bubbles that are connected are hilighted when the mouse moves over them.
The points you would score for popping the hilighted bubbles is shown at the top right.
The current score is shown in the top left and the High score is in the centre.
When bubbles are popped, the bubbles above drop down into their place.
If an entire column is emptied, the bubbles to the left move to fill the gap.
The game ends when there are no more groups of two or more bubbles to pop.
