Mr.Puzzle is always a good resource for your toy and gadget needs, and here he’s reviewing one called the Half-H that requires some creative spatial thinking to solve. The puzzle consists of several wooden blocks that should all be combined together to form a capital letter H. At first glance, just about every manner of building the H leaves out one piece.

Mr.Puzzle rates this a 3 out of 5 on his difficulty scale. Even without watching past the spoiler section of his video, the Half-H seems like it’s going to require some serious shenanigans to unravel. 

We’ve covered a few other particularly fun videos from his channel, including his assessments of the Ella Propella and the Revomaze. If you enjoy these physical brain teasers, then give his YouTube channel a follow.

Attention, puzzle fans! There’s a new review up on the Mr.Puzzle YouTube channel, an excellent source of reviews and solutions for the latest tinkering toys and amusements. This one is about the Ella Propella, from German company Constantin. It’s an acrylic dial sandwiched between a wooden propeller and a wooden disc base. The trick is to free a coin trapped between the dial and base. Mr.Puzzle doesn’t see this multi-layered containment trick as too difficult, but it does look like it could stymie the average sleuther for a little while.

Whether you’re on stage or in the audience, magic often calls on our critical thinking skills.

As an audience member, maybe you want to figure out how in the heck that ring levitated or that card just appeared at the top of the deck. For those of us who want a little guidance in building those problem-solving skills, there’s a YouTube channel to help you along.

It’s called Mr.Puzzle. The German host reviews all kinds of brain teasers and skill games, all with a bent toward taking a logical approach to finding solutions. The videos will usually have a clear spoiler notice if or when he is going to delve into the actual solution to a puzzle.
