Quite some time ago, I got a 3D print of Happiness Cube #20, from With the cube-filling add-ons to their pieces, the solution for each cube is unique. The burr pieces at the heart of each are:ġ27 - 61 solutions. Wayback Machine link Feb 2019 but missing images) showed 160 designs.Īlfons made three for me, including numbers 127, 135, and 151.2. Happiness Cube was published in 2006 (now out of print) The pieces are (with few exceptions) based on traditional burr pieces, augmented with additional cubies. Happiness Cubes - designed by Yukiyasu Sekoguchi, made by Alfons Eyckmans from Padauk.Įach cube is 6圆圆 and comprises six pieces. You can see the originals to which Lohe refers on my pages here:
My take on Andreas' idea has a slightly higher level 5.2.6.1.2 than Andreas' original. The bevels create channels which are partly empty, so it is not just a simple 3x3x3 puzzle. If the 3x3x3 volume is completely filled? It requires more than one move for the first piece. Markus Goetz' ECC had motivated Andreas Roever to his Non-Void Cube. My take on Markus' idea has a slightly higher level 1.13įor the removal of the second piece than Markus' original (level 1.9). Not only side by side, but also through some edge and corner connections. It looks like a simple 3x3x3 cube but the pieces connect cubies I was always fascinated by Markus Goetz' Edge-Corner Cube.

Tricky and non-orthogonal movements are needed to sequentially interlock and unlock the pieces during the solve.Ĭutting free the parts and construction of the pieces took me about three hours, and solving (assembling the puzzle) about a further two hours - there were a couple of moments where three hands would have been helpful during the solve, andĮdge Corner Cube Variation (green) and Non-Void Cube Variation (blue) -ģD printed by and purchased from Andrew Crowell It is a bit like a plastic Berrocal - the pieces are not simply polycubes - their shapes are intricate and the placement of each is not necessarily obvious, but with patience can be deduced. This is most definitely a sequential interlocking puzzle with rotations along the way, and I am very pleased with its overall quality. I attempted assembly guided only by images of the finished puzzle - many times I had made some headway when I realized that I had to unwind several steps to insert a new piece, and furthermore that rotations were required!

No instructions are included for how to assemble the puzzle from its pieces. The resulting puzzle pieces are all robust and none seem prone to break during normal play while respecting the typical mechanical puzzling prohibition against use of undue force.
The parts must all be cut free from the sprues, carefully trimmed, and then each puzzle piece can be assembled from its constituents according to included instructions.Įach of the puzzle's pieces comprises two or more parts.įortunately no glue is required - the parts press together, albeit with some firmness needed, and I found all the fits to be satisfyingly precise and snug - the parts are very unlikely to ever be unintentionally (or even intentionally) separated.
