A puzzle game where the aim is to clear all the colored squares from the grid.
To clear the grid you may select any tile that has formed a seamless block (horizontally or vertically) with another block or blocks of the same color. Choosing such a block removes all the blocks of the same color that where touching.
The blocks that are above any blocks that have been removed fall down until they reach another block. They may form more seamless tiles. Any column that becomes empty by removing the blocks, causes all the columns to right to move to the left.
