Triple Hex

From BluWiki

The Mind Ninja board can be divided into three overlapping sections, as illustrated in the pictures below.

Notice that each of the sections has two red edges and two blue edges. The builder must build a chain of red between the two red edges on at least two of the sections, for a total of at least two red chains. The chains may be embedded. An example of the completed pattern is given below.

If you are familiar with the game Hex, this is like playing three simultaneous games of Hex on three partially overlapping boards. Beware however: when you play the game, the sections will not be drawn onto the board, so you must either remember them or refer back to the pattern definition.
