Four in a Row vs noughts and crosses

Noughts and crosses (tic-tac-toe) is played on a small 3 × 3 grid and almost always ends in a draw between good players. Four in a Row is bigger, discs fall with gravity, and you need four in a line. That gives it far more strategy, and a skilled first player can force a win.
