PantaBram is Bram Cohen's variation to PantaCube, which is Oskar's variation to Pantazis Houlis' Cubedron. The puzzles has five pyramids that slide through grooves around a sphere. The groove pattern is an ultra-simple maze, suggested by Bram. Because of this maze, pieces can slide only one at a time (unlike regular twisty puzzles). This puzzles is very hard to solve, despite its low number of pieces.
