What makes Pentaminos fascinating is its initial simplicity, so different from the enigmas and problems. Unlike a 1000-piece puzzle, which has a single solution, the Pentominoes, while consisting of only 12 pieces, has thousands of possible solutions.

The Pentaminos (Pentominoes) is a polinimo, a term coined in 1953 by the North American mathematician and engineer Solomon W. Golomb to describe geometric figures made up of identical square sides joined by their edges. 

Altogether there are 12 different Pentaminos (Pentominoes), each designated by a different letter of the alphabet: (F, I, L, N, P, T, U, V, W, X, Y, Z). Pentominoes obtained by joining others at their axis or by rotation are not considered to be ‘different’ Pentominoes.

 The Traditional Game

The object of the traditional Pentominoes game varies, and with time and practice, a variety of problems and enigmas can be created.

Our Contribution

Our Pentaminos is three-dimensional, meaning that the figures that you build can stand freely and be seen from different angles. You can choose to follow the Pentominoes rules or to freely create figures, structures that are balanced or not, or figures that contravene in some way the strict mathematical precepts governing some of the proposed enigmas and problems. The pieces comprising our Pentaminos contain space; their emptiness allows us to gaze through them, seeing nothing but their outlines. All of these features provide practically limitless possibilities for the construction of fascinating visual worlds. We hope that in using it you take a step beyond the suggested enigmas and find your own language.
