Player guide

Connect Four beginner notes

The middle columns create more possible lines than the edges. Start near the center, check for immediate threats, and avoid giving yellow an easy winning space.

Strategy

The center gives you more routes

A disc near the middle can join more horizontal and diagonal lines than a disc at the edge. That makes the center a useful place to begin, as long as yellow does not have an immediate threat elsewhere.

Before every move, scan for groups of three. Block yellow first if its fourth space is playable. When your own line has two open finishing spaces, the browser can stop only one of them.
