“I began my puzzling with Belt Cube 3 (my copy came with a gorgeous Purpleheart box and Wenge pieces but it will also be available with the reverse colouring). This takes the usual packing puzzle which we love so much to a whole new level of frustration and cleverness. With a box/frame and holes in it and a few simple pieces to be placed inside which completely fill the aforementioned holes leaving no gaps visible, we usually have to create a 3x3x2 shape inside which, despite such simple shapes, is quite a tremendous challenge. This time we have a 3x3x3 cube to be constructed and two HUGE diagonally opposite windows to put pieces in and then fill. There is so much space to use that I expected this not to be much of a challenge… Oh, how wrong I was! Your usual play outside of the box reveals several simple shapesthat can be used to fill the visible 2×2 cubes on opposite sides. Getting these 2 cubes opposite each other proved quite a challenge. I found a few possibilities quite quickly and began to try assembling them in the box. Oh boy! That doesn’t work quite so easily! I spent a couple of days playing with this with my Bash Street Kids, Plug face on and amusing Mrs S before I had a very unexpected Aha! moment. What I realised was really very clever and just perfect Osanori – he has made a bigger better version of all the puzzles we have tried before.”
