Overview

Pente is an abstract strategy game played on a 19x19 grid (like a Go board). Players place stones on intersections, aiming to be the first to get five stones in a row or capture five pairs of opponent’s stones.

Components

Setup

  1. The board starts empty.
  2. The first player places one stone on the center intersection.
  3. Players alternate placing one stone per turn on any empty intersection.

Turn Structure

On your turn, place one stone on any empty intersection on the board. That is your entire turn.

Actions

Placement

Place one stone on any empty intersection. Stones are never moved once placed (except when captured).

Captures

A capture occurs when you place a stone that creates a pattern where exactly two of your opponent’s stones are flanked between two of your stones in a straight line (horizontal, vertical, or diagonal). The two captured stones are removed from the board.

Scoring / Victory Conditions

Two ways to win:

  1. Five in a row: Get 5 or more of your stones in an unbroken line (horizontal, vertical, or diagonal).
  2. Five captures: Capture 5 pairs (10 stones total) of your opponent’s stones.
