🧠GridLock Strategy Tips
Control the Center
Central lines influence more boxes than edges. Prioritize the middle of the board to maximize your options.
The Double-Cross Technique
Sacrifice a small chain of 2 boxes to force your opponent to open a larger chain for you. This is the key to advanced play.
Think Ahead
Every line you draw changes the board. Avoid completing the third side of a box — you're handing your opponent a free capture.
Count the Lines
In the endgame, count remaining lines to predict who gets the last move. Parity decides close games.
