HOW TO PLAY

1. A game for two players, one player plays with X and the other plays with O.
2. The goal is to put down an unbroken line of three of your symbol, vertically, horizontally or diagonally.
3. Players take turns, each turn has two parts. In the first part the player places their symbol in one of the squares on the board. In the second part, the player can EITHER place a wall along the horizontal or vertical side of one square OR place a wall at the edge of the board to expand the size of the grid.
4. If a wall stands between two symbols, they are no longer connecting and thus three in a row cannot be achieved using those two symbols and a third.
5. Diagonal lines are only blocked if two perpendicular walls meet at the corner of a square such that one of the symbols is inside the right angle of the walls.
