Instead of normal cube-based pieces, this packing puzzle by Wim Zwaan is based on the cube shape with half-cubes attached. There are 11 pieces; there are two objectives: firstly, to fill up the box so that no pieces stick out, and secondly, to make a cube shape using 10 of the pieces.
Designed by Wim Zwaan and made in Hevea and Samena by Philos. Philos is a German puzzle manufacturer that started in 1996 as a manufacturer and distributor of toys. They make a wide variety of wooden puzzles, as well as some less common strategy games, playing cards, and dice.
