Classifies as 2.1 trick/secret opening. About 8cm across, mainly laser-cut MDF, top layer acrylic and below some wood veneer. Goal is to get the coin out, some steps are involved. This puzzle was manufactured by Siebenstein Spiele (Jürgen Reiche) and was the exchange puzzle for Allen Stein (puzzlemaster.ca) at IPP35 Ottawa.
Note that the picture of two puzzles is just to encourage you to look at the other lot, this lot is for the puzzle on the left only.
Reviews: (top layer veneer is different from the one on auction)
