I do not know what "Diz Puz" means; so if anyone has an answer for these two words, please feel free to drop me a comment. I bought this puzzle from UK online puzzle retailer Puzzle-This. The Diz Puz is a 3-piece burr invented by Edward Disley and inspired by the Maltese Cross.
Made out of very hard plastic (or possibly ABS), the Diz Puz consists of 3 identical pieces each about 14cm long and 3.3cm square. When solved, it is actually a pretty large puzzle. It comes in a choice of three bright colours including blue and red. Overall quality and construction is very good and this is an item I have no hesitation to hand over to my 2 year old for him to mess around with. It is a very sturdy and durable puzzle and can withstand destructive forces.
The puzzle came to me unsolved. While it comprises only 3 pieces, it is fairly challenging and took me a good 20 minutes or so to figure out how to assemble it into the solved state. Once assembled, the pieces interlock and the puzzle would not come apart thereafter, even with violent shaking. Dexterity is required here and "connecting" the 3 pieces is not as easy as it would seem. Dis-assembly of the puzzle was more difficult than I had expected. However, in both instances, no force is whatsoever is required. Repeated solving is also not that easy.
For such a large, durable and well-made puzzle that is manufactured in the UK, the Diz Puz is truly value for money. In bright yellow, it looks pretty cool and snazzy as well.
