Rekubus Challenger 3D Puzzle is the latest addition to my puzzle collection (again thanks to my brother).
Rekubus Challenger is basically two puzzles into one. First you need to find out how the put the 3D cube together as there are 38 pieces. The second object is to place all the pieces so each face of the cube shows the numbers 1 to 9 in a sequence. Once complete it looks a bit like a Sudoku Cube, but no Sudoku rules applied.
If you would like more information about Rekubus Challenger you can visit the Rekubus website (in German only). Happy Puzzling!
