Gregory has this to say about Tronc Commun: Tronc commun is based on the following idea: the two main pieces are common to the three puzzles: TC1, TC2 and TC3. I named those 2 main pieces tronc commun (common core in English) The common core is surrounded by 3 different sets of pieces forming TC1, TC2 and TC3. The level of difficulty increases with the number. One is easier, and Three is very very difficult. Finding the exact move to assemble the first three pieces of TC3 pieces is more than com...

Called the "Reactor Box", this diminutive 1.75" cube has several tricks up its sleeve! When you finally solve it all you're rewarded with a shiny prize.Construction of this puzzle is VERY precise, with solid, snappy motion and an excellent fit. There are very small parts in the Reactor Box which are easily lost...care must be taken during solving to not misplace them.NOTE: B-Box puzzle by Goh Pit Khiam  not included. This puzzle was originally sold inside the B-Box, this is just the React...

Alexander Magyarics wrote about it:“2D and 3D packing problems are my favourites, especially those with only a few pieces, together with a sufficient level of difficulty. I hope you will like Pincers and add it to your collection. You do not need to create the illusion of a full cube inside (like we all do with amazing packing designs by Osanori). Just fit the three pieces below the top layer. So what is the clue here? – the shapes of the pieces and box opening. Study them well to eliminate ...

Kevin Sadler wrote about it:“Triangle ring looks like it might be fairly easy due to the huge amount of manipulation space available with the 2 holes in the frame. However counteracting this is the fact that the pieces to be placed have a total of 26 cubies and thus there is only a single gap to allow the pieces to move once packed. The solution is an absolutely beautiful logical progression which you will only find by thought and not random movements. A brilliant starter for this release seri...

Ray took the Slideways design and went a lot further down the road with his Double Slideways design! With two sets of three identical notch-able pieces, it's very tricky and confusing to solve. This was Rays exchange puzzle for IPP this year and from what I hear it was very well received. A limited number have been finished and prepared for sale here; when they're gone they're gone! Quite different from your standard six piece burr, this will lurk on the shelves like the surprise it is...*******...

The ODD Puzzle is a wonderfully challenging packing problem. Three rather large pieces must somehow fit through a wholly inadequate seeming slot to fill the box. The solution is creative and satisfying! This puzzle was the grand prize winner at IPP28.Construction of this puzzle excellent, with very precise cuts. The splines reinforce the mitered corner ensuring a long lasting joint. Fit is perfect, as it must be for this type of puzzle.************************************************************...

RAR! How could I not make a puzzle named after dinosaur sounds?! Seriously though, this is one of the most unique designs I've seen in a long while, and I predict it will sell out very quickly. An unusual seven pieces forms a very unusual L shaped burr with a unique level 9.15.1.6 solution. The mechanics are odd and surprising...overall this is a super fun puzzle that will add a unique touch to any puzzle collection.Construction of this puzzle is outstanding, with splined mitered corners and sho...

I saw this puzzle on Ishino's excellent site and thought it was interesting. While I was browsing, I was playing around with a leftover matchbox from Oskar's Matchboxes that I had fitted with a couple magnets to keep the drawer closed. Then it hit me! Make the packing puzzle in a small format just like the Matchboxes puzzle! The result is a pocket portable packing puzzle, beautifully made, which will not slide open and fall all over the place thanks to the magnets. Furthermore, the box is two si...

This release's cube offering is the very tricky and unique "Worm Cube" by Askerli. Each piece features concentric rings on two planes, which makes figuring out what goes where a very tricky endeavor. The level 7.2.2.1.3 solution gives nothing away. I cannot stress enough how confusing and difficult this puzzle is to reassemble. You've been warned!This copy features a mixture of various exotic hardwood species, which is unique from the cherry production copies. **********************************...

Markus designed this puzzle quite a while ago and I always liked the looks of it. Finally I emailed him asking if the design was free...and it was! One hitch though - there was more than one solution. I greatly prefer puzzles with a single solution, so I decided to enlist Tom Jolly to see if it could be modified into a single solution. Tom quickly determined that the original had at least 15 solutions. Both Tom and Markus subsequently went to work, both coming up with interesting variations. In ...
