If packing puzzles weren't already difficult to solve, Jean Claude Constantin makes them even more challenging by always adding a twist. After all, we like challenging puzzles, don't we? My recent addition to this ever-growing collection of difficult puzzles is called Nimm 2. The name indicates that there may be a first Nimm, but in reality Nimm in German means "take", so the name can be translated as "Take 2". Read more and you'll understand the meaning.

This is a nice small puzzle, measuring only 8cm x 8cm (3.2"). It is made from laser-cut wood, so the price is more affordable. There are 7 pieces, but they can be divided by two groups: one is a group of three trominos and the other a group of four tetrominos. Each piece has one or two screws attached to it, which makes for an interesting design. The idea is to have two screws in every row (vertical and horizontal). Diagonals don't count. It sounds simple enough, but believe me, this is a fiendish one to solve.

Solving the puzzle without worrying about the screws is very easy. That's why the designer wanted to make it as simple as possible. However, packing the pieces with the one rule mentioned above is more than just a simple exercise. It requires patience, and much trial and error. But that's what most packing puzzles require, so it's asking you anything new. If you're used to solving this kind of puzzles you know how to go about solving them, at least in principle...

As you can imagine, this is quite a difficult puzzle to solve. It's rated as a level 8/10, but I reckon it's possibly even more than that. I'm yet to find the solution, which might be a unique configuration, and thus explaining why it's so challenging.

Closing Comments:

Nimm 2 by Constantin is a hell of a challenge. If you like this type of puzzles, you're in for a treat, because it'll keep you busy for a while. I liked the originality of the design. It's different from any packing puzzle I've tried before.
