Structures

The base of the 11 Towers allows to create other structures as the tetrahedron using the same set of bars.

Many of these structures present one or more possible alignments (in some cases with 9 lines just like the tetrahedron), with even a structure that allows aligning 3 balls in 14 different ways.

This procedure allows to play cooperatively and also competitively.

You can also play in a paper board by copying the figure on the right (or downloading the pdf below) and trimming the numbered circles (corresponding to the bars) and the colored ones (corresponding to balls of different colors).
