Outback is a puzzle design from Stewart Coffin.
There are five pieces you must try and fit within the frame but this is no easy solve, there is only one known solution.
The pieces are made from cherry and maple and come with a nice base. The puzzle comes unsolved with the rectangular maple piece sitting outside the main frame. There are five possible combinations for fitting the four larger pieces into the frame and even solving these is not particularly easy!
The puzzle measures 89 x 140mm including the base and cover.
If you need help the solution is included.
