Gomoku

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

Put your marker on any empty point of the board. Aim to create a sequence of 5 pieces in a row, either sideways, vertically, or at an angle. Prevent your rival from achieving their own row of 5. Alternate placing markers with your opponent until one contestant achieves in creating a row of five. Note that the game finishes immediately when a line of five is created, with no need to fill the entire board.
