The skewb is an interesting puzzle, it is still a cube but it turns completely differently from other cubes with each turn being a 120° turn of an entire half of the puzzle. The skewb has 3,149,280 possible combinations, similar in number to the 2x2x2, it is not too difficult to solve but does require a very different solving method to standard cubes. I have a range of excellent skewbs available in the UK.
