About this Product
A new 4x4x4 interlocking puzzle cube designed by Jeff Namkung. This complex puzzle requires a sequence of 9 moves to get the first piece out which is a new world record for solid faced 4x4x4 interlocking cubes. This is a great puzzle that prints beautifully in this larger, 4 cm size and should be solvable by any good puzzler. It took me about 15 minutes to find the solution (without cheating and using a computer).
If you like this one, you might also like to have a look at Bolero by Jeff Namkung. It has one less move for first piece removal but is significant harder.
