In Determinant Tic-Tac-Toe, Player 1 enters a 1 in an empty 3x3 matrix. Player 0 counters with a 0 in a vacant position and play continues in turn until the 3x3 matrix is completed with five 1s and four 0s.
What they need is an RSS feed. hmm....

Putnam Problem of the day...
Harvard has a Putnam Exam page that contains (apart from all the Harvard rah-rahing), a "problem of the day". Today's problem:
In Determinant Tic-Tac-Toe, Player 1 enters a 1 in an empty 3x3 matrix. Player 0 counters with a 0 in a vacant position and play continues in turn until the 3x3 matrix is completed with five 1s and four 0s.Player i wins if the determinant is iPlayer 0 wins if the determinant is 0 and Player 1 wins otherwise (thanks, Amit). Assuming optimal strategies from both players, who wins and how ?
