## Surround – Kohno Ichiro

I’m back in the puzzling groove and this week, I’ve got Surround designed by Kohno Ichiro and masterfully crafted by Eric Fuller over at Cubicdissection.

There have been a number of Ichiro puzzles released by CD recently, including Three Cubes, Four Cubes, and most recently Five Cubes and Surround. I’ve really enjoyed these puzzles. They are relatively easy, but also deceptively tricky. They are great puzzles for all skill levels and very satisfying to complete. The use of small, strong magnets really adds to the experience.

Ok, I’m excited to work on this one, so let’s get started. There are apparently 3 solutions to this puzzle – 2 that use the magnets and one that does not. The completed structure needs to be self-supporting.

There are 6 pieces and a cube. 3 of the pieces are mirrored which would lead be to believe that this is going to be a symmetrical solution, but I’ve been wrong many times before on things like this, so let’s see what happens.

Ok, well my first attempt was a total failure. I figured, I’d start with the cube and just add the pieces to the perimeter to surround it, but that did not work at all. The magnets didn’t cooperate that the resulting shape certainly did not surround the cube. Ok cool, I didn’t want this to be easy. Let’s give it another 15 minutes and see what’s up.

Ok, interesting. I believe that I have found one of the solutions – one that utilizes the magnets. It seems that my initial interpretation of “surrounding” the cube was incorrectly understood as “completely cover” the cube. And thus, I was searching for a solution that didn’t exist. Once I let go of that idea, and simply tried to surround the cube, I found a solution quite quickly. The cube is indeed surrounded and contained and the puzzle is self-supporting. Yay! Solution #1 is in the bank! And it is quite a cool looking construct that has formed. The Padauk and Tamerindo make for a beautiful contrast on the completed piece.

Now, onward to see if I can find solution #2.

Well, it too me another 30 minutes or so, but I’ve successfully found solution 2. Interestingly, it is very similar to the first solution, if I hadn’t taken a picture of the first solution, I’m not sure that I would have know that the configuration was different. But, sure enough, it is different. The center cube is a little less covered with this solution, but it is still very pleasing to handle and display.

Overall, a very fun and pleasing puzzle to work on and solve.

After sitting on this puzzle for another day, I decided to try to find the third solution. This one required covering the cube completely, but didn’t use the magnets. After about 10 minutes of fiddling, I was able to find the solution – it didn’t look pretty, but the cube was entirely covered.

So there you have it. 3 solution to one puzzle. I really enjoyed it and am happy to have it in my collection. The only question that remains is: Will we see another incarnation of this puzzle? A 7 or 8 piece configuration? I’m not sure that there is much left – and in fact, since I own, the 3,4,5 piece and surround, I could play with combining those to see if anything interesting happens.

## Spheres – Stephan Baumegger

Spheres arrive yesterday and I’m just now sitting down to play with it. My first impression is – “Wow!” This puzzle is beautiful. The box is exquisite, the lid fits nice and tight, the pieces are really nice looking and I especially like the choice of “spheres” used. I’m so glad Stephan chose to go with these natural stone spheres instead of silver ball bearings. They add a nice contrast, yet still fit perfectly into the overall color scheme. This puzzle is definitely a show stopper.

The object of the puzzle is to cram everything inside and shut the lid. I suppose there will be little cramming and mostly planning, arranging and sliding, but either way, it’s all gotta fit.

Well, enough gibber gabber, I’m ready to start solving this thing.

A few minutes pass and I’ve gotten a little more familiar with the pieces. There are 3 sets of 2 pieces that mirror each other and 3 balls. The thing that is throwing me off is the smaller ball. It would seem that this puzzle will require a symmetrical pack, but then, where does that leave the 3rd ball? I’ll have to try some non-symmetrical arrangements as well to see if that’s the key.

About 15 minutes later and I’m not any closer to the solution. The pieces are fun to play with and there seem to be an endless amount of arrangements. I can easily get the 6 sticks into the box with 1 large ball, but that’s as close as I’ve come.

Ok, another few minutes and I’m starting to realize that this is not going to be sloppy pack. I don’t know why it would be, but there’s something about including these “spheres” that makes me feel at liberty to let them roll around a bit, thus resulting in a sloppy pack. My new strategy is to pack tightly. Let there be no unfilled negative space inside the cube. If there is space, then it is wrong. Let’s see how this approach goes.

Hmm. well, for a few minutes there, I thought I was on to something – I had a nice tight pack going with 3 pieces, but then things fell apart and did not progress from there. Back to the drawing board!

Failure again!

Bah! I thought I had it, but then looked down and saw one more stick! I got 5 sticks and 3 balls in… Does that count for anything? No? Well, ok then. Let’s have another try.

Whelp it looks like I’m going to remained stumped for this session. In total, I worked for about 45 minutes. And I have to say, so far it’s been delightful. I keen thinking that I’m on the right track only to find out that I’m not – which is great for a puzzle. This thing gives the impression that you are making progress, which keeps motivating me to try one more combination, and another and another. But, I’ve now burned my allocated time for puzzling today and must return later for another attempt.

Ok. I’m back again on another day to see what I can see. I’m quite drawn to this particular puzzle. I think its the combination of elements (sticks and spheres) that makes it interesting.

Annnnnd, I’m back in the same cycle of failure. I really thought I had it, but alas, there doesn’t seem to be any room left in this darn box for that final piece. Once again, I face the realization that I can’t leave any empty space anywhere.

Zing! I did it!

Very, very cool and enjoyable puzzle! I was on the right track the whole time, I knew what had to be done, it was just a matter of time until I found the correct arrangement that allowed all the pieces to fit. And there is definitely something unique involved when it comes to packing spheres. Had those spheres simply been squares of wood instead, I don’t think the puzzle would have been nearly as enjoyable and I’d wager that it would have been easier to solve as well. Again there is something about those spheres that tricks the mind (my mind at least) into believing that a “sloppy pack” is going to work.

Overall, a fantastic puzzle. The box is beautiful, the pieces are fun to play with and the puzzle as a whole has a nice hefty weight to it. This may be the first puzzle I’ve ordered from Stephan, but it certainly won’t be the last!
