Welcome to the official website for the Herzberger Quader

The Herzberger Quader¹⁾ is a puzzle for the development of spatial imagination. If you want to know more about it, Wikipedia knows everything.

If you combine identical cubes, you get one pair, two trios, and exactly eight different quartets. In total, these eleven pieces consist of 40 individual cubes, which can be assembled to form a 5×4×2 rectangular cuboid.

The inventor gave the elements abbreviations and easy-to-remember German names:

• 2: Twin [Zweier]
• Ⅲ (Roman three): Straight triplet [gerader Dreier]
• 3: Angled triplet [abgewinkelter Dreier]
• S: Stick [Stange]
• P: Plate [Platte]
• H: Hook [Haken]
• T: Stairs [Treppe]
• A: Car [Auto]
• L: Left hand [Linke Hand]
• D: Tripod [Dreibein]
• R: Right hand [Rechte Hand]

Anyone familiar with the Soma cube knows that it consists of seven pieces: Angled triplet (3), Hook (H), Car (A), Stairs (T), Left hand (L), Right hand (R), and Tripod (D). By adding the four rectangular blocks Twin (2), Straight triplet (Ⅲ), Stick (S), and Plate (P), you get a wide variety of new challenges. A considerable number of them, along with background information and instructions, will be featured in Rainer Gutsche’s book, published in 2025.

In principle, anyone can make their own Herzberger Quader. All you need to do is glue together 40 high-quality wooden cubes using the right adhesive and a bit of skill. If that's too much trouble, or if you're not sure you can do it yourself, or if you'd like to have both the box and the instruction booklet to go with it, you can order the Herzberger Quader right here.
