Gomoku

Connect exactly 5 of the same stones in a row (horizontally, vertically or diagonally).

Set your piece on any vacant point of the board. Try to make a row of 5 markers in a sequence, either horizontally, vertically, or diagonally. Prevent your competitor from completing their own sequence of five. Alternate putting markers with your competitor until one player wins in forming a line of five. Remember that the contest ends immediately when a line of five is created, with no need to fill the entire board.
