Matrix Brain Twister — a puzzle game in which you need to solve matrices, filling all the blocks with one color. If you click a block, the block itself and its horizontal and vertical neighbors will change color instead of rotating, as in a Rubik’s cube. The matrix is solved if all blocks are filled with one color except white. This is a very simple game mechanics, but it can lead to very complex puzzles. True to the motto that says easy to learn, hard to master. Several matrix formats, such as 2D hourglass, skull, star, 3D octahedron, pyramid, sphere, 4D hypercube, pentachoron, octaplex. More than 600 manually created levels, from simple to complex.
