I have nearly every Melting Block version, and this is the best. The metal pieces are gorgeous. Both packings are quite difficult to find. Plus the smallest piece is not a duplicate. Not for beginners, I save my original for that.

This is a really fun puzzle with high replay value. I definitely recommend this for fans of maze puzzles.

A very difficult puzzle to solve. Took me a long time with countless moves, and I found the reset feature quite nice when I screwed up. The quality of the puzzle is great, really recommend it, a must-have to add to your collection. Very high re-play value too.

I absolutely love this iteration of Melting Block! It really does pose quite the challenge as I’m still trying to solve it! A definite very fun challenge for sure!!

This puzzle is simple and not too hard but it is still really fun and satisfying to solve and share with other people :)

This is a variation on a classic puzzle but the classic has and even number of pieces so they are paired up and them packed in an odd way. This one has 9 pieces and is easily packed in the tray but consistently has the last piece NOT fitting flush in the tray. Hmmm. What possible packing arrangement can get all of the pieces in the tray flush and below the top of the frame ???

The solve on this one made me chuckle to myself. Such a great trick!

What a great fiddler! Love playing around with this one, looks great, feels great, love it!

Great construction and fun little puzzle. Very elegant solution though not particularly difficult.

Love the combo of metal and wood. Excellent construction and fun puzzle! Both solutions are quite difficult to work out which is a marked difference from previous versions, but there’s a nice logic to narrow down the solution space if you think about it a bit.

packaged great, fast shipping. puzzle was a blast to do

Great design and superior workmanship!

Amazing puzzle! Terrific work you guys! The sounds of the blocks together is so satisfying.

TriLox is an upgrade to an already well known Lox in a Box puzzle. However, this is the version you want to show off to all your friends, coworkers, and family! It’s the perfect balance between simplicity and complexity in terms of puzzling. Leave it on your coffee table or desk to fiddle with or share with others when a much needed break is in order. Not to mention, the brass and aluminum pieces feel so good in the hand and the price can’t be beat! So be sure to pick one up while they’re still available!

Jammed Gem is the result of Eric and Frederic coming together with their evil genius brains to produce a puzzle so incredible and brilliant that it could easily be considered one of the best hybrid puzzles ever created! What a thrill it was to solve this puzzle. So many twists and turns and then moments, rather hours in my case, of being completely stuck. But when the fog lifted and the aha moment became clear…the solve was so sweet! This puzzle is solid, beautiful, and a lovely puzzle to display in any collection! I highly recommend any puzzle enthusiast to purchase Jammed Gem!
