“Fritz Pingl (FRITZ-FLOP) and Dick Fosbury (DICK-FLOP) are the namesakes of my FLOP SERIES. The rotation of individual pieces in these unique packing puzzles is reminiscent of their high jump techniques. While I was recently playing with my STEFKA-FLOP, named after Stefka Kostadinova, I unexpectedly found a new solution. This is, of course, terrible, since every FLOP is supposed to have exactly one solution. But this new solution is so beautiful – not least because, just like with the FRITZ-FLOP, the opening can be compressed to exactly half of one of the square sides – that I don’t want to keep this experience from you. A production by Pelikan was a must.
 
While searching for a suitable name, I learned that Stefka Kostadinova’s long-standing world record in the high jump from 1987 was surpassed in 2024 by Yaroslava Mahuchikh with a jump of 2.10 meters. So I dedicate my YASYA-FLOP to this exceptional Ukrainian athlete, who is affectionately called Yasya by her friends. While solving the YASYA-FLOP won’t let you set a new world record, I hope you understand why this solution has remained undiscovered until now.”

“Another puzzle in the “Flop” series is one that is not to be missed. There have been quite a few so far and this one is by far the most difficult. Jakub and team have made this from a wonderful Saman wood (aka Monkeypod) and Purpleheart. It arrives with all but one of the pieces packed in the box and took me quite a bit of fiddling to actually remove the pieces. This bodes for a very difficult solution to get all of them back inside. 
 
The box has a 3x3x3 cavity and a 1½ voxel wide slot in the top through which all the pieces of a standard Soma cube need to be placed. I have mentioned many times that I am terrible at assembly puzzles. My appreciation of this occurred many years ago when I bought my first Soma cube. So here, I need to find one particular assembly of the Soma cube and then work out which orientation to try and then how to get the damn thing into a box through a small hole using rotational moves! Does this sound like fun to you? Yes, it does to me too.

There is an immediate way to cut down the possible assemblies as the final pieces to be placed have to be able to drop straight in through the opening as there will be no room for rotations at that stage. This helps considerably but if I was you, I’d have a BT set of Soma solutions available to search through.
 
In the end, due to time constraints, I had to get the solution from Pelikan to give me the intended assembly and orientation and then work out how to get it inside the box. The movements are very complex and require considerable dexterity as well as judicious use of gravity to place pieces. Make sure that you know what you have done as taking the pieces out will be almost impossible. This is an amazing challenge but definitely only for the most expert of puzzlers.”
