Here's a high-tech, high-strategy juggling act that's loads of fun! Are you up to the challenge? You've got to get R.O.B., the World's first Robotic Operating Buddy, to stack a pile of colored discs to match the colored pattern on the screen. This exciting Robot game can be played several ways. In the Direct mode, you have to match the pattern in the shortest number of moves. In the Memory mode, you can program up to 100 Robot moves as you try to match the pattern. In the Bingo mode, on-screen alien beings keep changing the pattern, preventing you from completing your mission! Inside you'll find five colored discs and five disc holders along with the game pak. Everything you need to play STACK-UP!
