Description

Meridians is an annihilation game featuring anti-connection and territory as emergent themes. The game was invented by Kanare Kato in 2021.

Rules

DEFINITIONS
Group: like-colored stones adjacent to each other. Singletons are considered groups of size 1.
Path: an empty point, or an uninterrupted straight line of empty points that have a pair of like-colored stones on both ends, which are not part of the same group. Such a pair is said to have a path.
Dead group: a group in which all stones belonging to it have no path. If any stone belonging to a group has a path, the group is said to have a path.

GAME PLAY (Overview)
Decide which player plays as which color (Light or Dark) in any adequate way.
Light goes first, then alternate turns.
On each player's first turn, players place a stone of their own color on any empty point.
On each player's second turn, players place another stone of their color so that their own two stones have a path.

Then players take actions below on each turn, in this order.
1. Remove all opponent’s dead groups. This happens automatically in Ludii.
2. Place a stone of their own color on an empty point that is on at least one same straight line with an existing friendly stone, and no opponent's stone in between. Passing is not allowed.

After the second turn, the player with no stones of their color on the board at the beginning of their turn loses.
