The third edition of the wildly popular Cluebox was inspired by the fantastical imagination of Jules Verne. An escape room that fits in the palm of your hand, Cluebox 3 is an unsinkable challenge worthy of Captan Nemo himself. You'll have to crack codes and solve mysteries to unlock the secrets hidden within this brilliant wooden puzzle box. Experts can solve this sequential discovery sequence in under an hour but even if you complete the puzzle in less than 90 minutes you should be proud. Constructed from 116 precisely designed birch wood pieces (more complex than any previous Cluebox), this ingeniously designed adventure is a testament to modern laser cutting technology. Once you've completed the experience, reset the pieces, and pass the puzzle on to a friend so they too can discover the treasure hidden within Captain Nemo's unsinkable box.

Joshua ★★★★★ Sep 13, 2026

The Jules Verne angle really shows in the little brass details and engraved plates, and figuring out the final lock took me the better part of an evening. It's the closest thing to a pocket-sized escape room I've tried, and I passed it to my brother the next day.

Andrew ★★★★☆ Sep 15, 2026

The little brass compass detail on the lid genuinely stumped me for a good ten minutes. Everything fits together beautifully once you figure out the trick, though the last lock felt a touch fiddly with my larger fingers. Solid way to kill an evening.

Took me and my wife about an hour to crack, and the little brass dial mechanism near the end genuinely stumped us both. The wood feels solid in hand, though one of the sliding panels is a touch stiff. Fun gift for anyone who likes escape rooms.
