Open the game: Pente JS
Win by making five stones in a row, or by capturing 10 enemy stones.
On your turn, place one stone on any empty intersection (cell center in this UI).
You capture two stones when your newly placed stone and an existing friendly stone surround exactly two enemy stones in a straight line.
Game ends immediately when a player has five in a row or reaches 10 captured stones. If board fills first, game is a draw.
