Loved this puzzle! Such an awesome 'aha' solve. There's a reason these sold out on Cubic Dissection. Just making room for new puzzles. Unfortunately, my dog got a hold of one of the pieces (seen in the picture). Just a couple marks but it in NO WAY impacts the solve. Here's the description from the Cubic Dissection site:
The artisan series is being discontinued; once these puzzles are gone they will not be remade.
Stumbling Blocks is a brilliant puzzle that I've been wanting to make for a while. When Pit mentioned that he had a more difficult version I jumped at the chance to make it. Packing the four pieces into the frame is the goal, and the way to get there is amazing. I can't tell much about this puzzle without giving things away, but I'll say that it has one of the best "Ah-ha!" moments I've seen for a while. The movement of the pieces is beautiful and this puzzle rates incredibly high in overall satisfaction.
