Curiously, many of the piece dimensions are multiples of 7, but I wasn't able to figure out how to exploit this. But perhaps there is a clue there.Georgehttps://www.blogger.com/profile/10140920751826036814noreply@blogger.comtag:blogger.com,1999:blog-7408525737943998966.post-62134003764398809912012-06-06T19:33:14.297+01:002012-06-06T19:33:14.297+01:00Wow, that is impressive.

And an interesting fact about the puzzle is that when it was originally designed, the description was that the pieces formed a rectangular area, but this area was not specified. Pavel Curtis sells this puzzle too, but without a frame, which is even harder a challenge.Gabrielhttps://www.blogger.com/profile/00547574234341454265noreply@blogger.comtag:blogger.com,1999:blog-7408525737943998966.post-29531969683480996052012-06-06T19:20:41.012+01:002012-06-06T19:20:41.012+01:00By the way, the puzzle is not easy even for BurrTo...By the way, the puzzle is not easy even for BurrTools.

I solved it using BurrTools. The next paragraph gives a small hint, stop reading now if you don't want one ...<br /><br /><br /><br />There are two pairs of identical rectangles. In the solution, the two 21x18 rectangles do not touch one another, but the two 21x14 rectangles share an edge and can be combined into a rectangle of twice the area.Georgehttps://www.blogger.com/profile/10140920751826036814noreply@blogger.com
