|Tronc Commun 3|
I finally got my package a week later and I took my customary photos before having a play. The first piece comes out nice and easily (Level 1) and then the adventure really begins. The next step requires another 5 moves and requires a rotation. There are a few possible moves to choose from but it is not too hard and just gives a hint that some really fun things are going to come later. As is usual Brian had made the puzzle absolutely perfect and everything slides beautifully with no catching and just the right amount of friction. Once the second piece is out, there is a lot of movement in the puzzle and it gets frightening as everything seems to want to go in every direction. With a bit of discipline it is possible to isolate the possible movements and be systematic and there's a lovely Aha! moment when the progression to the third piece removal ends in a very unexpected sequence with even more rotations and 7 more moves. This leaves the 2 large main central pieces encircled by a ring and everything moves in all sorts of directions.
The fourth piece comes out after a further 14 moves. This feature of pieces requiring progressively more moves is very unique to the TICs; it is more common with other interlocking puzzles and burrs that after the first piece or two come out then it gets progressively easier. It was at this point that I got properly stuck. The encircling ring can rotate freely and the 2 main pieces can move all over the place. Finding a useful move that seems to progress towards the solution evaded me for a couple of days. I did find a very interesting move that spun the 2 main pieces around each other at a very odd angle and then I hit a wall! There was a LOT of swearing and sweating because I had gotten into a very entangled position and not only could I not get it back to the start, I had actually wedged them all solid and no moves were possible at all! I genuinely thought I had permanently jammed my new toy. I left it overnight and the following day tried again (that was NOT a good night's sleep). Luckily I somehow released the jam and after a whole evening of trying managed to get those three remaining pieces back to the start and breathed a sigh of relief. Time to think© - man, that really hurts my tiny brain!
Thinking didn't help so I moved on to fiddling and trying simpler moves. Aha! I found something very interesting after another evening and then there was a release of another piece. The final 2 came apart after a further 4 moves giving a final puzzling level of 18.104.22.168.4
Is this one as good as Tronc Commun 4? Not quite, but it's not far off it. I am truly delighted that I have both in my collection in fine gorgeous wood and can recommend purchasing or making a copy if you get a chance. Brian has sold out of these but maybe he will make more in the future?
The first 3 pieces come out pretty simply - the puzzle has an initial level of 1.1.1 which in itself is very unusual. On top of that looking at the pieces that do come out reveals a hind for why the puzzle has the name - these are very strange shapes! After that I was a bit stuck. I had a vague recollection from the MPP that there were some very unusual rotations now and several pieces would turn or move together. I tried a few different things and almost dropped it on the cat again when a most unexpected move occurred - it was almost horrific with a huge rotation AND a coordinate movement at the same time! It was so unusual that I felt it could not be incorrect and lead to a blind end so I continued further along that path. More strange moves were possible and almost a logical progression occurred. The oddly shaped pieces locked together beautifully to allow others to come out. I managed to dismantle it in a single evening of wonderment!
|Just look at those odd shapes! Slanted cube pieces indeed!|
I would say that these two puzzles are amongst the very best TICs ever designed. My top TICs are:
- Tronc Commun 4
- Slant Cube
- Tronc Commun 3
- Changing Partners
- Twist the Night Away
- Little Kenny
- Little Bruce
- Dizzy Cube
- Threaded cube
I am sure there are many others that I have forgotten about. I absolutely adore this particular genre of puzzle and have to blame the brilliant Bernhard Schweitzer for leading me into this group! I cannot wait to find some more and work on them.
