Ken Irvine is one of the best designers out there, and Matador is one of his Turning Interlocking Cubes series. The five piece puzzle has a tricky level 4.10 solution with some very unusual movements. The pieces interlock almost like rings or chain pieces, and the "ah-ha" is a very fun one indeed.
Construction of this puzzle is excellent, with our usual precise yet easily moved fit we use for cubes.
