Description

Pente is a modern take on the two classic Japanese board games Go and its variant Gomoku, devised in the 1970's by Gary Gabriel in the United States. It combines the basic game play and rules of Gomoku with Go's ability to capture your opponent's stones (pieces). Pente is played on a 19 x 19 Go board.

This rules/instructions page covers straight Pente. Here at Pocket-Monkey, we also have Pro Pente, Keryo-Pente, and Pro Keryo-Pente.

Instructions

Objective

Get five or more stones (pieces) in a row horizontally, vertically, or diagonally; or capture 10 (or more) of your opponent's stones.

Rules

  • Game Play
    Play starts with Player 1 placing a stone in the center of the board. Thereafter, each player takes their turn by placing a stone in any open position on the board. Play continues until one player wins or the board is filled with stones.

  • Capturing
    You can capture two of your opponent's stones by placing a stone next to them such that you have a stone on either side of the two, like so:

    Example of Black capturing two of White's stones
    Example of Black capturing two of White's stones

    Note that you can only capture on your turn, by placing a stone. You don't capture if your opponent places a stone in-between yours. For instance, if White places a stone like so:

    Example of White placing safely between Black's stones

    ...it's not a capture for Black because Black didn't place the stone to create the situation.

    You can capture more than once with the same move. In this example, Black is capturing four of White's stones by doing two captures simultaneously:

    (It may be possible (though rarely) to manage three or even more simultaneous captures, although it's extremely unlikely as it requires a very specific arrangement of stones.)

  • Winning the Game
    There are two ways to win in Pente:
    • Get five or more stones in a row horizontally, vertically, or diagonally
    • Capture 10 (or more) of the other player's stones
    (Note the difference from Gomoku, where there are no captures and where you must get exactly five in a row.) In each case, the player wins immediately; there is no final turn for the losing player.

  • Terminology
    There are two quite powerful formations in Pente:
    • Tria - A tria is three stones of the same color in a row with no stones on either end. A tria is powerful because it can become a tessera on the next turn, if it isn't blocked.
    • Tessera - A tessera is four stones of the same color in a row with no stones on either end. If you have a tessera, your opponent cannot block it and unless they can capture one of the stones of the tessera on their turn, you'll win on your next move by placing the fifth stone on one end or the other.
    (In some clubs, it's customary to announce it to your opponent when you create either of these formations; the idea being that you want to win because you have out-maneuvered your opponent, not because they just messed up and didn't see the formation. However, this is not in any way obligatory and many clubs play without this piece of etiquette. You'll find most Pocket-Monkey players, like most Pente players everywhere, are unaware of this custom and don't announce their formations. Players should not expect that thir opponents will announce formations, nor take offense.)
