Triune is an abstract strategy game in which players begin with a set number of soldiers (16 if 2 players, 12 if 3, 8 if 4) and attempt to reduce the other player(s) to 2 soldiers. You do so by building triunes (or rows of three soldiers in a line) each time you move one of your soldiers to create triune with two others, you get to remove one soldier belonging to an opponent. The game has a kind of Roman-ish theme, with legionnaire type soldier pieces. - BoardGameGeek
