Visible Framed Burr

This is another variation of Framed Burr.

Unlike ordinary Framed Burrs, the checkouts of each piece can be seen from the outside when the puzzle is completely assembled. Thanks to the feature of the shape of the frame, the puzzle requires some very tricky 24 moves to take the first piece apart.

Juno had the original idea of Visible Framed Burr in 2012 and he has been occasionally thinking of how to make the puzzle to have a unique solution. If you input the shape of pieces of the picture below into the puzzle solving program like BurrTools, it will find 34 solutions and most of them could be solved by two or three moves. Using several colors for the pieces is one of the solutions but Juno took a different option to make the puzzle have a unique solution. The modification to the pieces gives you a big hint to find out the orientation of the pieces but even if you know the orientation, the puzzle is diabolically difficult.

Reinforcement Jarrah pieces were inserted to the ends of the top and bottom panels and it prevents cupping deformation of the panels. The joints of the posts to the panel are recessed to keep the accuracy of the dimension of the frame.

The puzzle is sold assembled. The printed solution of the puzzle is enclosed.
