Magiq #8 & Tango 72

For this year's IPP36 Nob Yoshigahara Puzzle Design Competition, I submitted two entries. One was my own design (the subject of this post) while the second was a joint entry with fellow puzzler Primitivo Familiar Ramos, which I shall write about at a later date.

START

My first entry was called Magiq#8 and the goal (as can be seen from the photos) is to re-arrange the 5 pieces and change the #8 to a #0. Saying "abracadabra" would certainly help! I didn't manage to win any prizes...but hey, its the participation that counts right? 

Although this year's design bears some resemblance to my entry at last year's IPP competition, the "69", the Magiq#8 is totally different in terms of the solve. My design was expertly crafted by Tom Lensch and consists of exotic woods comprising walnut, holly, shedua and yellowheart. Construction, fit and finish is excellent and I particularly liked the perimeter trim added by Tom to the top edge of the box.

SOLVED STATE

Its not as straight forward a packing puzzle as one might expect and there is a trick to it. No spoilers so I shall not say anymore. What's the difficulty level? I can't say as I have not received any feedback so far, although puzzler Marc Pawliger did casually mention to me in the competition room that he found it quite devilish... If anyone is keen to purchase a copy, please contact Tom Lensch via his website to check on availability. 

My Exchange Puzzle is "Tango 72". This year, I designed a sliding block puzzle consisting of 5 pieces, 4 of which are identical. Like most sliding puzzles, the goal is to rearrange the pieces from a starting position to an end position, while only moving the pieces (left, right, up and down) within the tray.

END

Here the end result is to form the words IPP36 from a scrambled state. It takes a minimum 72 moves to arrive at the final solution. I tried to make my design accommodate an additional but easier challenge with fewer moves, but somehow didn't quite manage to succeed. Tango 72 is made from 3mm laser cut acrylic and I have a couple of copies left for sale if anyone is interested.
