• You are the light coins. Pocket all nine before your rival clears the dark ones.
• Slide the striker left and right along your baseline at the bottom.
• Drag backwards from anywhere on the board to aim and load power, then let go.
• Pocket one of yours and you shoot again. Miss and the turn passes.
• The red queen must be covered: pocket her, then sink one of your own coins on your very next shot. Fail to cover and she goes back to the centre.
• Fouls - pocketing the striker, or pocketing your rival's coin - put one of your coins back on the board and end your turn.
• Clear your nine coins with the queen covered to win the board.

On a keyboard: arrows aim and set power, Space shoots, A and D slide the striker.
