Continuing in the tradition of naming my puzzles after the places where they were invented, here is my latest brand new puzzle design.
Ludlow is an interlocking 6 piece 4x4x4 puzzle cube. To assemble this puzzle you will need to discover the correct sequence of sliding and rotational moves as the pieces become locked together. Be warned - as you slot the last piece into the solid cubic outline, there is no simple way to push it out again. The pieces are carefully designed to fit together snugly so it should not fall out on its own. Fortunately, the hollow design of the pieces means that it will be quite easy to hook it out with a small tool or knock it out by tapping the correct face of the cube against your hand.
