| Play |
|
A game begins with an empty board. Each player has an allocated color, usually Red and Blue. Players take turns placing a stone of their color on any empty cell of the board. Since the first player has a distinct advantage, the pie rule is generally used for making the game fair. This rule allows the second player to switch colors after the first player makes his first move. |
| End of Game |
|
The game ends up when one of the players forms a connected chain of his stones linking all the board edges. Corners of the board belong to both edges of the board. No draws are possible in "Y". |
