Gomoku

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

Put your stone on any vacant point of the board. Strive to form a row of five pieces in a sequence, either sideways, up and down, or diagonally. Prevent your rival from achieving their own row of 5. Take turns putting markers with your opponent until one participant succeeds in creating a line of 5. Remember that the contest ends immediately when a line of five is made, with no need to cover the entire board.
