From a small 3x3 board that is easy to get used to, to a giant 21x21 that requires deep thinking, the game allows you to choose the size of the board as you like. You can also adjust the winning conditions: 3 or 5 consecutive symbols and a time limit for each turn, making the game more thrilling and requiring more careful calculation. When playing on large boards, players need to grasp long-term strategies and occupy space more effectively to win.
