How to Play
Standard: Connect 5 stones in a row (horizontally, vertically, or diagonally) to win.
Vanish: Stones disappear from sight after a few seconds. You must remember where they are!
Renju: Black (P1) has restricted moves (no double-threes or double-fours) to balance the game.
Swap2: A tournament opening where P1 places 3 stones, and P2 chooses to stay, swap colors, or place 2 more and let P1 choose color.
