Kuborabu is a puzzle game and both children and adults can play. The gameplay is based on rolling the character [a cube-crab] along paths of blocks that are revealed as Kuborabu moves, until it reaches his target. The challenge is to go through all the blocks. It is not possible to go back, as the block the character passed through gots locked. As the player finishes a path, another opens, with a greater degree of difficulty. Each path is generated randomly.

The combination of the words “cubo” and “crab” (cube in Portuguese) resulted in the name Kuborabu, and the spelling and sound refer to a word of Japanese origin.
