Penta-Tri

The Penta-Tri is a “packing puzzle.” The idea is to move all 12 moveable pieces from one side of the divided tray to the other. The pieces are arranged in 3 layers, and there are several non-moveable pieces in each side of the divided tray.

We rate the Penta-Tri puzzle as Difficult. There are only 2 solutions.

The Penta-Tri is made of Semana hardwood and comes with an 8 page booklet that contains the solution diagrams. The booklet also gives some challenges to construct other shapes from the pieces when they are not in the tray.

Here’s the maker’s description:

“Based on the idea of Polyomino by Solomon Golomb (1953) the German collector of puzzles, Bernhard Schweitzer developed a flat variant of the Pentomino game in 1988 called Penta-Tri. There are 12 pieces with different forms consisting of 5 units each. They have to be laid in 3 layers with blank fields at the same place in each layer. All 12 Pentomino pieces of the left part of the box have to be moved into the right part. Note: There are only the two given possibilities to place the pieces within the box.”
