The puzzle consists of 16 silver plastic pieces with no straight edges. Your challenge is to fit the 16 pieces together in a 4 x 4 square with no straight edges.
How can a 16 piece jigsaw be that difficult? The front of the pieces is smooth. The back of each piece is textured. If you try the puzzle with the smooth face of each piece up there are over 250,000 INCORRECT solutions. If you mix the pieces there are even more possibilities.....
You can also compete for prizes up to Euros 15000 when you've solved the puzzle. Details of entry on the pack.
