Gomoku

Place your marker on any unoccupied spot of the board. Strive to create a line of five stones in a sequence, either horizontally, vertically, or at an angle. Stop your competitor from completing their own line of 5. Switch placing pieces with your opponent until one participant succeeds in forming a sequence of 5. Remember that the game finishes immediately when a row of 5 is created, with no need to cover the entire board.
