Oskar developed a prototype of the puzzle, which is now produced as Pyraminx Duo.Pyraminx Duo is arguably the easiest non-trivial twisty puzzle. It can always be solved in four moves when it has plain stickers, and in seven moves with oriented stickers. The puzzle’s limited difficulty, combined with its attractive look and high fiddle factor, makes it a perfect puzzle gift, also to beginners.
