Stack-Up is an Action game, developed and published by Nintendo, which was released in 1985.
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 & 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.
