Especially non-cooperative, zero-sum games with perfect information like Chess, Go, Reversi (Othello), n-in-a-row (Pente, Gomoku, Renju), Checkers (Draughts), Chinese Checkers (Halma), Abalone, Amazons, Arimaa, Dots-and-Boxes etc. will be dealt with. They are ideally suited for playing over the internet (low traffic).
Besides related areas (single agent, cellular automata, combinatorics, graph/group/complexity/knot theory, quasicrystals, discrete geometry, computational algebra, mathematical physics) are discussed as we occasionally encounter them, so actually the XiStrat™ project belongs to a wider field of general recreational mathematics.
