To win Oxono, you must be the first player to align 4 pawns of the same color, no matter the symbols, or 4 pawns of the same symbol, no matter the color.

Choose a totem (X or O) to play at your turn. Then move it as many spaces as you want in a vertical or horizontal row of the board. Once you have placed a totem on its destination square, you must immediately place one of your pawns with the same symbol as the totem you just moved on an orthogonally adjacent free space around the totem's new position.
