It is not available very often; the beautiful Pachinko box by Wil Strijbos is made in limited quantities and is highly sought after by the avid puzzler.
The puzzle consists of 3 phases:
1. Free the first coin while the box is still closed;
2. Open the box
3. And finally free the second coin.
The puzzle is made of aluminum and steel and all puzzles feature Wil's signature and a number, 450 in this case. It weighs about 1.4 kg and is about 12 x 10 x 7 cm. It will be shipped in a nice storage box. As with all of Wil's puzzles, no force, forcing, or tools are required to solve the puzzle. Turn, slide, feel and listen. And above all, use your ingenuity.
