"?? Game rules: Pentrix (Gomoku)
??Basic information
Number of players: 2

Board size: 15×15 (can also be changed to 13×13 or 19×19 as variations)

Color of chess pieces: black and white, each person holds one color

Goal: The first person to connect five consecutive chess pieces of the same color horizontally, vertically or diagonally on the board wins.

?? Detailed explanation of game rules
1. Opening rules
Black moves first (the "no hand" rule can be used to balance the first mover advantage, see below)

The initial chessboard is empty

2. Rules of placement
Players take turns placing one of their pieces at the intersection of the board.

Once the chess piece is put down, it cannot be moved or withdrawn (no regrets, unless negotiated by both parties)

3. Determination of victory or defeat
The first player to form five consecutive pieces on any straight line wins.

More than five consecutive chess pieces (such as six consecutive pieces) will still be considered a victory.

For example: ⚫⚫⚫⚫⚫⚫ (six consecutive runs) is also considered a victory


?? Tie rule
If the board is full and no one has formed a five-match series, it will be deemed a draw."
