Can You Fit The Nine Jigsaw-Shaped Puzzle Pieces Into A 6x6 Grid?

Choose one of the 120 multi-level challenges. Set up the challenge as shown and then position all nine of the sections of jigsaw pieces to complete a 6x6 square. Beware though, because the pieces can be positioned in various orientations and either side up, so what looks straightforward enough may well leave you well and truly puzzled! Plus, each challenge has only one possible solution! A truly wonderful set of puzzles!
