While the prototype was labeled SCRMNN, the actual title of this game is currently unknown (some have speculated that the name on the label might stand for "Screen Manipulation"). Found in a salvage yard in 1998 by Ben Liashenko, the identity of this mysterious Activision prototype has eluded collectors for years. This prototype plays like a cross between a Rubik's Cube and the old sliding tile puzzle game. The goal of the game is to line up all the colors in each row from light to dark. If you've done it correctly the board should look like the start-up screen with the colors descending from red to purple. However lining up all the colors is easier said than done due to the unique way the squares move across the board. When you move your square up or down a row or column, the last square in that row will move behind your square's new position. For instance if your square is the light green one (center of the row), and you move it left it will result in the last square in the row (the light blue one) moving behind it. If you move right instead, the last square on the right (the dark blue one) would move behind your square. Mastering how the squares move is essential to solving the puzzle. If you forget what order the squares should go in, pressing the fire button will cause all the squares in the correct positions to turn black. While this is helpful for positioning the shades of color in each row, it won't help you remember what color is supposed to go in each row.
