IceTowers is a turnless strategy game designed by Andrew Looney and published by Looney Labs. The game is played with a set of Icehouse pieces, with each player assigned a specific color.
The pieces are initially scattered on the playing surface, and placed upright. Play then consists of forming and modifying towers made from the pyramids, with the goal being to control towers by having one's pieces on top. The three types of moves are capping, mining, and splitting.
You may place one of your pieces on top of a tower, provided the top piece on that tower is not of your color, and is no smaller than the piece being used to cap.
You may remove one of your pieces from a tower you don't control, provided you have two or more pieces in it.
If a tower contains two pieces of another player's color next to each other, you may split the tower between them, creating two new towers.
Once the players agree that they have no more moves they wish to (or CAN) make, points are scored based on the total pieces in the towers players control. Large pieces are worth 3 points, medium pieces are worth 2, and small pieces are worth 1.
