The rules of the game are much similar to classic Collapse game brought into three-dimensional world. It allows you to reveal your skills in strategy and spatial reasoning. The goal of the game is to remove all the blocks. Blocks of the same color are gathered into groups thus forming the cylinder. When you click a group that contains bricks of the same color, it disappears. The group should contain two or more bricks on Easy and Medium levels and three or more bricks on hard level to be deleted. The more bricks the group contains, the more points you get. To form the group you may rotate the rings of the cylinder. Clicking right mouse button rotates the ring you choose pointing to it. Red arrows on the left or right side of the ring will prompt you the direction of rotation. There are two types of game: Remover - strategic puzzle game. If you prefer thinking and working out the strategy, choose this game. You have no any restrictions and may think over each move to find the most favorable solution. The game is over when you remove all the groups or when you remove all the bricks that can form the groups. If any bricks that cannot be deleted remain on the board, you lose.

Collapse - arcade style game Clear the blocks before they reach the top. The time before new blocks appear in the bottom decreases within the game. To make new bricks appear on a board before the time is up click the block generation ring on the bottom of the board.
