At the start, advance your marbles quickly toward the center of the board

Marbles in the center are much safer, and can move around more easily, than ones near the edge. And, if you can occupy the center, you will also force your opponent’s marbles to stay near the edge (unless your opponent can outwit you and take over the center).

Keep your marbles together Your marbles are strongest in a solid group. The more lines in which you have connected rows of three or more marbles, the harder it will be for your opponent to push you back toward the edge.

“Divide and Conquer” Try to separate the opponent’s marbles into two or more groups. Smaller groups will be easier to push back and trap against the edge of the board, where they will be lost.
