A very clever packing puzzle by Rob Hegge, IPP31 exchange. The packing frame is damaged, it was cut incredibly thin at the bottom (see second photo). This has no effect on the puzzle.

IPP22 exchange from Dick Hess. Just pack the 6 half-circles into the square! There is a slightly larger frame on the back of this puzzle which is much easier to solve. Comes with a solution page. The fit on the front frame is very tight. It is a lot more fun to work on packing the frame on the back.

IPP30 exchange puzzle by Hiroshi Yamamoto. Pack the 9 "acrobats" in the frame. Nicely packaged in a CD case. Not overly difficult, but fun.

IPP31 exchange puzzle by Pavel Curtis. A hard puzzle to classify as it is both put together and sequential discovery. The goal is to discover the "secret answer".I requested tips from Pavel to solve this, but I eventually got it. I wanted to make it available to others to have the fun of solving it!
