Each player in turn uses the cue ball to try and hit other balls into the six pockets situated along the two sides and at the corners of the table. This is called 'potting'. The player's turn ends when he either scores no points during his turn or plays a 'foul shot' (this will be defined later). When the red balls are potted, they are not replaced, unlike other coloured balls.

Whenever red balls are present on the table, the player must first pot a red. If successful, then he must try to pot another colour. If successful, he can attempt to pot a red ball again. When all red balls are potted then the player must try and pot other balls in ascending order of their colour values.

A 'snooker' is defined as no clear line of sight between the cue ball and any valid balls.

Foul Shots:
The cue ball must hit the ball of the appropriate colour first. Failure to hit any ball, or hitting the wrong colour ball constitutes a foul shot. The opposing player then gains either 4 points or the value of the ball which should have been hit, whichever gives him the most points. If the cue ball ends up in the pocket, then the opponent has 4 points OR the value of the ball which the cue ball first touched. The cue ball will then be put back on the table.

Foul Snooker:
If by means of a foul shot a player causes his opponent to be snookered, i.e. there is no clear line of sight to a valid ball, then his opponent may ask him to play the shot.

Scoring

The green and brown balls are represented on screen by the colours cyan and flashing magenta respectively.

A score board at the top of the screen displays the scores of both players. An arrow at the right of the score board indicates whose turn it is.

The green strip at the bottom of the screen represents the cache in which the balls are collected when potted.

Game Controls
Using the Z, X, : and / keys, the cue is 'drawn' on the screen pointing in the direction of the intended shot. The length of the cue determines how hard the shot will be: the longer it is, the harder the shot, and the cue ball goes in the direction of the extended cue.

To complete a shot, press either S, B or T according to whether you want a Normal Shot, a Backspin or a Topspin.
