Cu-On-Pa SFC is a puzzle game in which the player takes control of a cube, the object being to roll this cube over squares of a particular colour. If the top face of the cube matches the colour of the square, it is collected; claim enough squares to move onto the next level.
Essentially, this is a Super Famicom port of the 1995 PC game Endorfun - in fact, Cu-On-Pa is licensed from Endorfun. Cu-On-Pa features none of the new-age stylings of the earlier game, instead opting for a more traditional puzzle game aesthetic. This version offers a couple of new features over Endorfun: there is an Easy Mode, which reduces the available colours from six down to three; and there is also a Puzzle Mode which gives the player predefined boards to solve, and a limited number of moves to do so.
