Four in a Row rewards players who think in lines, not columns. Gravity fixes each piece in place, so every drop is permanent and mistakes compound downward. This guide teaches how to build double threats, control key columns—including the center—and recognize fork patterns that force wins within two moves. You will learn why height matters, how to block without setting up opponent wins, and endgame ideas when the board fills. Strong play blends offense and defense: create two winning threats at once when possible, and when defending, prefer moves that still advance your own lines.
