The bombs are black (in which case clicking on them causes the surrounding blocks to disappear), or are the color of one of the groups of bricks (in which case clicking on the bomb eliminates all bricks on the board that are the same color). In higher levels of the game, "bombs" appear, mixed among the blocks. New colors may also be introduced, making it more challenging for the player to find groups that are large enough to be collapsed. During the course of a level, the rate of new blocks entering the feed increases. When the feeder row has filled, all of its blocks are moved up, to the active board, shifting the field of remaining blocks higher. One after the other, new blocks are added to a "feed" row below the board. Ī level usually begins with a few rows of blocks using a starting set of colors (typically red, green, blue, white, and yellow.).

If the player manages to survive a specified number of lines without losing, they win the level and are awarded points for successful completion. If one or more blocks rise beyond the top row of the board, the game is lost.

If a whole column is cleared, the elements slide to the center of the field. By clicking on a group of 3 or more blocks of the same color, the whole group disappears in a collapse and any blocks stacked above fall down to fill in the vacant spaces. Randomly colored blocks fill the board, rising from below. The classic Collapse! game is played on a board of twelve columns by fifteen rows.
