Gomoku

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

Place your stone on any empty intersection of the board. Aim to form a line of five stones in a sequence, either sideways, up and down, or diagonally. Block your opponent from completing their own line of five. Take turns putting markers with your competitor until one player achieves in creating a sequence of 5. Note that the contest finishes immediately when a row of 5 is formed, with no need to occupy the entire board.
