Seven pieces fit into four trays. The main tray is double sided. The pieces are cleverly supplied with knobs, which make them easier to grab and also prevent you from turning them over. Includes instructions. This puzzle was constructed without using any glue, another clever detail.

Use the four pieces to make a symmetric shape. I found this to be very challenging. IPP32 exchange puzzle.

Anansi's Maze, designed by Pavel Curtis. This lovely acrylic puzzle was a good bit of fun to solve. Placing "all 12 pieces flat in the tray" is really not a puzzle at all; but putting them in so that the letters don't overlap is tricky. Then, figuring out the hidden message is also tricky. That leads you to the third puzzle. Anyway, the puzzle was a little journey of solutions, and quite satisfying; took somewhat less than an hour to solve. Impressive design from 2009.
