Gomoku

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

Place your piece on any empty point of the board. Aim to form a sequence of five markers in a line, either sideways, up and down, or diagonally. Stop your opponent from forming their own row of five. Switch placing stones with your competitor until one participant succeeds in forming a sequence of five. Keep in mind that the match concludes immediately when a sequence of 5 is made, with no need to fill the entire board.
