Gomoku

Put your piece on any unoccupied point of the board. Aim to make a row of five stones in a line, either horizontally, vertically, or diagonally. Block your rival from achieving their own sequence of five. Take turns setting markers with your opponent until one participant wins in making a row of 5. Keep in mind that the contest finishes immediately when a line of 5 is created, with no need to cover the entire board.
