Matrix Brain Twister is a puzzle game, where you have to solve matrices by filling all blocks with the same color. If a block is clicked, the block itself and its horizontal and vertical neighbours will change their color instead of a rotation like the Rubic's Cube. The matrix is solved, if all blocks are filled with the same color, except white. This is a very simple game mechanic, but can lead to very difficult riddles. True to the motto: Easy to learn, hard to master.
