Pyraminx Duo
The Pyraminx Duo is a 4-sided puzzle with 4 corner pieces and 4 triangular face centres. You can rotate the corner pieces and, when you do, you rotate the centre piece with it.
Although it is a nice puzzle to look at and it turns nicely, the puzzle is trivial. Restoring the corners is really simple and it takes a few turns more to put the centres back into position.
