We'll, only took me 4 days! Lol
Saw one person's review who said it took them an hour and a half. I wasn't even close. I had to walk away some days and revisit with fresh eyes. After a little bit you start to get the hang of it. It does get a little easier. But you do have to use your brain and powers of observation very keenly. Having the right lighting seemed to be key for me. It definitely was challenging and I highly recommend it. I have a penguin and baby penguin puzzle set coming next. I'm looking forward to that. If you take away the platform the key and the post that holds it all together, there's actually only 39 pieces. You'd think it would go up in a snap, but it does not I'm here to tell you. I highly recommend it if you'd like a challenge. Plus it looks pretty when you're all done and can put it on the shelf. I'm hooked. NOTE: I too put down a dark towel to work on it as it made the pieces easier to see.
