G4G8 Exchange Book
Each of our two-person games is a word version variation from the tic-tac-toe or noughts and crosses family. It is well known that classic tic-tac-toe is a draw when expertly played. It is also clear that not all of its plays are equal- a strong move for the first player is to initially take the powerul center square. ASTEROID and ASTEROID II, on the other hand, are both completely symmetric (in the sense that all letters are used equally) and each have rather suble forced wins for either the first or second player.
