Games@Dal 2016 talk: "Eternal Picaria" - Israel Rocha w/Urban Larsson
Israel Rocha presented a new game to me: Picaria. Picaria is a traditional board game of the Zuni tribe from the American southwest, but it also pops up in other parts of the world, including southwest Sweden (known there as a type of Luffarshack). It plays a bit like a Three Mens Morris mixed with Tic-Tac-Toe.
Players play on a graph, usually set up in a 3x3 grid like Tic-Tac-Toe, but with diagonal connections as well. In the first six turns, players are playing pieces, trying to make three-in-a-row. After those pieces are played, players instead slide pieces to an adjacent location, still trying to make a line of three.
Israel explained that he and Urban Larsson showed that Picaria is a draw, via exhaustive search. (And without a computer!) They then considered some variants, including giving a player more stones and playing on bigger boards.
