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.
