Four in a Row — Rules

Misère

A 7×6 board, a two-game match, unrated. One rule turns the whole game upside down: whoever lines up four in a row loses. The caption "Make a row — lose the game" stays above the board for the whole game.

If the board fills up and nobody has a row, the game is a draw.

You have to think in reverse: make sure your own disc never lands as the fourth one, and force the opponent into a position where any move completes their row.
