Eicosiexaedron

Choose the level and shape the combination to open the polyhedron.

By clicking on the home screen button, you enter the game. A window opens in which appears a rhombicuboctahedron positioned in the center and, depending on the chosen configuration, a series of side keys on the left and on the right of the polyhedron or only the keys on the right. The purpose of the keys on the left is to rotate the polyhedron around the three main axes, while the keys on the right slide the three corresponding octagonal stripes with the same color.

The goal of the game is to position the faces of the polyhedron in such a way as to form the combination 16652034 on two of the octagonal strips of the solid. If the game is closed, an automatic saving of the current configuration is performed, which can be resumed when the game is restarted by selecting "Recover" from the initial window menu.
