Hepto Master

The game includes a 26 x 26 cm board and 108 unique pieces called heptominos. Each heptomino is made up of seven adjoining squares, each square measuring 8 mm on each side. These pieces represent all possible configurations of heptominos, as explained here on Wikipedia. The pieces are divided into four sets of 27, each in a different color, and they are double-sided, adding an extra layer of complexity.

Game Rules:

• Objective: Arrange all the pieces on the board to completely cover it.
• Fundamental Rule: Two pieces of the same color must never touch, whether by an edge or a corner. This principle is based on the Four-Color Theorem, which you can learn about here.

A Unique Challenge in the World:

The Hepto Master is considered one of the most difficult puzzles ever created. And for good reason: no one else in the world has solved it yet.

However, the solution does exist – it was designed and validated by its creator. You could be the first to discover it yourself!

Why Is It So Complex?

• With 108 heptominos, each of which can be placed front or back, the number of possible combinations is staggering.
• Adding the color and contact constraints creates a devilishly difficult puzzle.

The total number of possible combinations to arrange the 108 heptominos on the board, considering their double-sided orientation but without applying the color and contact constraints, is astronomical:

4.3 x 10⁹⁵ (a number with 96 digits!).
