Stack-Up (also known as Robot Block and simply Block (ブロック Burokku?) in Japan) is a video game released in 1985 for the Nintendo Entertainment System, designed for use with R.O.B. the Robotic Operating Buddy. Stack-Up is one of two games in Nintendo's Robot Series, the other being Gyromite (Robot Gyro in Japan). While Gyromite is a pack-in game with the R.O.B. itself and therefore comes with all the parts needed to play the game, Stack-Up comes in a large box containing additional bases and colored discs. The game's retail box comes with many, many small, plastic parts, which may contribute to difficulty in maintaining a complete set. Stack-Up is considered by those who are in the know to be one of the rarest first-party games for the NES.
Because 1985's newly released NES game console is internally compatible with 1983's Famicom game console, all Stack-Up GamePak cartridges contain the 60-pin circuit board of a Famicom cartridge, attached to a 72-pin adapter like the T89 Cartridge Converter for the NES. This GamePak may be disassembled to reclaim its Famicom-to-NES adapter, for use in modifying other Famicom cartridges to work on NES.
In some modes, Professor Hector works with R.O.B. to organize blocks. In others, Hector competes for control of R.O.B. against "glitches" named Spike and Flipper, or against Professor Vector.
The player must direct Professor Hector to jump onto buttons, that each activate an action for R.O.B., in a sequence in order to get R.O.B. to arrange the colored discs in a certain order on the five pedestals around R.O.B.
Like the other single-player modes, the player progresses through phases by moving the blocks from one arrangement to another, but in this mode block colors are irrelevant, and the difficulty is derived from the method used to control R.O.B. The screen is occupied by a 5x5 bingo board that Professor Hector hops around on. Rows on the bingo board correspond to R.O.B. commands; and when a row is completed, the command is executed. The computer-controlled enemies Spike and Flipper roam about, and touching either one will send Professor Hector flying back to the starting position. Spike wanders randomly; but Flipper moves in straight lines from one side of a row to another, activating and deactivating spaces wherever he lands, potentially sending undesired commands to R.O.B. The game ends when a block is dropped.
