How to Play

Click to place a disc adjacent to your opponent’s line; any straight line of their discs between your move and an existing disc of yours flips to your color. The goal is to finish the board with more discs than your opponent. Early on, prioritize stability over greed: corners are king because they can’t be flipped. Edges are safer than the center, especially when they help you approach a corner safely.

Avoid handing your opponent access to corners. If a move lets them take one on the next turn, it’s usually a mistake—even if you flip many discs right now.
