Riveting four-way action as colored pieces appear randomly along a grid and move toward the center. You must eliminate the colors before they enter the center square. If you strike a colored piece that is the same color as the center piece, that color will be eliminated. If you strike a piece of a different color, you will exchange colors with that piece and it will remain on the grid. If you eliminate enough colored pieces, you will move to the next level and the play intensity will increase. Those looking for something much more exciting than Tetris will quickly become enamoured with this gem. Stunning graphics, non-stop action and a superb game concept will have you coming back for more. This arcade puzzler game has a seriously high PLF (Productivity Lost Factor).
