Groovy Cubes 8 piece interlocking cube puzzle

Standard Range version made September 2005.  100 made.  All sold.
Original Price: AU$50.00

The puzzle is to build a solid cube from the eight pieces. Rick Eason invented this puzzle and presented it as his Exchange Puzzle at IPP24 in Tokyo in 2004 and it is with his kind permission that we make this puzzle.

All eight pieces of the puzzle are different which increases the degree of difficulty of the puzzle. There are four possible solutions but three of them are false solutions. A false solution is when all the pieces look like they will fit together, but there is no order of assembly that allows the puzzle to go together completely. To achieve the only possible correct solution you must find the unique combination of dovetails and grooves, and the correct order to assemble them, that allows the pieces to fit together to form the solid cube.

We have recently had a big clean up in the shed and found another set of 22 puzzles cut out and never completed. The wood will certainly be well dried by now and the puzzles are working beautifully.

The puzzle is crafted from Burdekin plum. Burdekin Plum is a very widespread species ranging in rainforests throughout northeast Queensland and extending south to the Mary River in SE Queensland. The heartwood ranges from pale to dark reddish-brown, usually streaked with darker coloured bands, close and usually straight grained. Packaged Disassembled for extra puzzling enjoyment.
Size: Each cube 30mm x 30mm x 30mm. Final puzzle 60mm x 60mm x 60mm.
