Gomoku

Set your marker on any unoccupied point of the board. Try to form a sequence of 5 stones in a row, either horizontally, vertically, or diagonally. Block your rival from achieving their own line of 5. Alternate setting markers with your opponent until one contestant wins in making a line of five. Keep in mind that the game finishes immediately when a row of five is made, with no need to cover the entire board.
