Tel Arad

The 'Tel Arad' is perhaps one of the more unusual puzzles I have come across. Certainly its a category of puzzles you don't see everyday, although it does remind me of the snake cube/snake man type puzzle. 

This is the brainchild and creation of Yael Meron (Ms) from Israel, with whom I had to pleasure of exchanging puzzles with at IPP34 in London in 2014. 

The name of the puzzle (according to Yael) "is inspired by the ancient Israelite city of Arad, located west of the Dead Sea. The site is a Tel, which is a type of archaeological mound created by layers of human settlements over centuries"  For more info on Tel Arad, click here.

The puzzle which is produced by Yael herself consist of 9 acrylic squares (3 of each size) which is bound together by bands. The object is to stack the squares, one inside another in three layers. The puzzle in the solved state measures 5cm x 5cm x 2cm. Now these are not rubber bands that stretch, otherwise the puzzle won't be much of challenge but rather the bands are 'non-stretchable" and they hold the squares together (quite tightly) as shown in the photo.

The starting position is as shown per the accompanying instructions (and in the photo of the puzzle) and the puzzler must stack the squares as per the solved position. Stacking the squares would obviously require the folding of one square over another, the smaller squares going into the bigger ones and so on. Simple to say, but the puzzle is actually much more difficult than it looks. Initially I was pretty gentle with the folding and twisting as I was not sure how much stress the bands can withstand without breaking. After a bit of fiddling, I realised that if you don't apply brute force, the bands are actually quite strong.

Random trying here and there may help but some logical thinking will help you solve the puzzle faster and reduce the chances of wear and possible tear of the bands. 

Definitely a rather unusual puzzle indeed and one which results in an elegant solution that surprises, and also no undue force whatsoever is needed (although wriggling is permitted to turn the squares held by the bands). The difficulty level is just right for an exchange puzzle.

As far as I can tell, this puzzle being a private exchange puzzle, is not available anywhere except perhaps from the designer. PM me if anyone is interested to acquire one and I will link you up with Yael Meron.
