Go back to the time of Nintendo’s R.O.B. with the Stack Up (Nintendo, 1985) game. This Nintendo game is designed to work with the Robotic Operating Buddy and is one of the two games in the Robot Series (Gyromite is the other). In this Robot series game, the player has to command R.O.B. to arrange colored blocks in random patterns and once this is done, you proceed to the next phase of gameplay. Professor Hector, another character in this Nintendo game, either works with R.O.B. or competes against Spike, Flipper, or Professor Vector to take control of him. This Robot series game features many levels and modes like Bingo (1P), Bingo (2P), Test, Direct, and Memory modes, giving you variety in gameplay. Enjoy punching buttons and controlling R.O.B. in the Stack Up (Nintendo, 1985).
