OXOXO rules


OXOXO is played on a board consisting of an equal number of squares wide and high. Initially all squares are empty. The goal of OXOXO is to be the first to form the required number of rows with the required number own marks.


Taking turns, the players put their mark (a cross or a circle) in one of the empty squares.


The first player to form the required number of rows (horizontally, vertically or diagonally) with the required number of his own marks wins the game.

Depending on the size of the board, the required numbers are as follows:
• 6x6: 1 row of 4 marks
• 10x10: 2 rows of 4 marks
• 15x15: 3 rows of 5 marks

When forming new rows, a maximum of 1 of the marks of each already laid row can be reused.
