First, arrange the game board using anywhere from 9 to 12 disks. Using 12 disks gives you the freedom for more placement options, while using a minimum of 9 disks provides a greater challenge. Arrange disks in a 4 x 3 or 3 x 3 grid patterns or in a variety of configurations to change the game.

Players play tiles in alternating turns, either matching pips or adding them to 8 (SUM8) anywhere tiles touch. The first player can place their tile anywhere on the game board -- additional tile placements must always touch another tile already on the board to form a continuous tile structure.

Optional: players can opt to move tiles on the board instead of placing one of their tiles to score points, thwart their opponent, or setup potentially larger scoring opportunities. Only two successive movements are allowed before a new tile must be played to ensure no play 'loops' are ever created. (Use moves sparingly near the end of the game since leftover tile points are deducted from your total score!) 

Place tiles to score the most points. Matching pips scores +1 point, adding to 8 or SUM8s score +2 points and 'BIG8s' score +4 points. Creating multiple 'BIG8s' at once scores the most points and can turn the tide in any game!
