Ochinai Soma is another wonderful variation on the seven piece Soma Cube. In addition to the standard seven Soma Cube pieces, two 'boxes' are included to provide the additional challenges.
The boxes each have two openings: both with one (almost) full three by three opening but with one corner slightly blocked off. Each box also has a second partial opening on the other side.
The goal is to assemble the Soma Cube in the box such that the cube stays in the box when held with the three by three opening facing down.
Another recommended Soma Cube variant, to add next to Greg's Shrinking Soma!

This is one incredible puzzle in the Minima style popularized by Frederic Boucher. Andreas Röver deserves some very high praise for this design as it adds the complexity of dynamic pieces. Those pieces are hinged and change within the confines of the box, which makes the solution that much more difficult to see. The interaction between the two hinged pieces is especially satisfying. This one will be on the same shelf of my puzzle cabinet as the 4L puzzle by Yasuhiro Hashimoto.

I underestimated it because of its simple appearance, assuming I could solve it in about ten minutes. I was terribly mistaken, though — it actually took me several hours to complete! It is the most challenging of all the two-piece puzzles I own — a brilliant puzzle that requires you to change your perspective.

A packing puzzle with a fresh twist! Although the pieces themselves are simple, the unique shape of the box makes the puzzle significantly more challenging. Personally, I found two particularly tricky spots, and the solution is far from obvious. I am confident that fans of challenging puzzles will be thoroughly satisfied.

Although there have been many challenges in the MINIMA series so far, this version features an entirely new method of solving the puzzle. Although it looks complex, it can be solved using logical, step-by-step reasoning. While it requires a touch of manual dexterity, I feeled the parts move with such smoothness that it is a puzzle I will want to try again and again.

A very clever puzzle. Great for puzzle newbies!

A very nice introduction into the many varied TIC line. Not the hardest, not the easiest. This one is a five-piece, with the first couple pieces trying to Trick you into thinking this one will be easy. Not so! The challenge is in the remaining three pieces, requiring attention be paid on their disassembly. Most heartily recommended, as is the whole TIC line. Enjoy!

Five start gift and conversation starter puzzle.
