The YuXin Corner Helicopter Cube is a 2x2x2 with a lot of twists, it can twist around the edges and also around the centres, giving 4 pieces in between each 2 corners, solving this is quite challenging and requires a fair amount of lateral thinking and patience, if you are interested in more challenging non-WCA puzzles then this is definitely something to consider.
