Amazing puzzle, have had puzzle for a long time and have only just managed to open it. Beautifully made as always from CD

Fantastic book for anyone interested in mechanical puzzles.

Great :-)

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!
