Gomoku

Place your stone on any empty intersection of the board. Aim to form a sequence of 5 markers in a row, either sideways, up and down, or diagonally. Block your opponent from forming their own line of five. Take turns setting stones with your competitor until one participant wins in creating a sequence of 5. Keep in mind that the match finishes immediately when a line of 5 is created, with no need to cover the entire board.
