At first, it’s like playing tic-tac-toe on a larger board with 2 extra players, but the game is a lot more complicated than that.

All players have now take 2 turns.

Player 1 has a clear advantage because going first means that they are the first to reach a point where they can connect 3 in a row.

Because Player 4 did not block Player 1, the latter wins.

If Player 4 blocks Player 1, Player 2 wins.

After the first game, it is Player 2’s turn to start and have that early advantage. The other players must now ally themselves to stop Player 2 from winning early whilst attempting to win themselves.
