Really hard puzzles

These are our hardest puzzles, some of them are really really challenging. See the customer reviews at the bottom of each page for more info.

What makes a puzzle hard is not just the image, but how we design the pieces. We have a few different tricks for designing hard pieces, like our split tendril connector pieces, and mini-hexagon pieces. 

Plus, most of these puzzles have an irregular edge, so don't think you can start by picking out the edge pieces!
