Fiendish 15 is a puzzle I've created, where the tiles have to be in the correct position and the correct orientation at the same time.

Help:
OK so you can solve the standard 15 puzzle upside down behind your back. Try this: the tiles are circular and each time you move a tile it rotates a little as though rolling along tracks that run between the tiles. The tracks are shown in red.

In all solutions the bottom right position is empty.

Level 1: the tiles rotate by 1/8 turn. Get the numbers in order and the right way up.
Level 2: same as level 1 but the tiles rotate by 1/12 turn.
Level 3: the tiles rotate by 1/8 turn but each tile contains a portion of a maze. Create a path from square 1 at the top left to square 15. The key rules are that dead ends in the maze occur only within a tile not at the edge and that coloured markers on the tiles must be adjacent eg green to green.
