The game TriskaidekaPool invites you to fight on the billiard table. A pyramid of multi-colored balls is already stacked at the edge of the field. The white ball is the cue ball that you will use to pocket the balls. There are only eight of them. You must score balls one at a time into the pockets; if, upon impact, two balls collide with values whose sum exceeds thirteen, icons will appear on the field - these are runes. Each rune has its own properties that will affect the game. Some will help, others will hinder. For example, when colliding with a rune in the form of a triangle, the ball will go into the pocket, wherever it is. Other runes can neutralize your achievements and all pocketed balls can return to the field in TriskaidekaPool.
