Myramid

Myramid is a triangular connection game for two players. In this game, players take turns placing triangular pieces on the triangular tiles of a triangular grid of side length ranging from 7 to 15.

Each turn, the player may either place a stone on an empty tile, or flip a "vulnerable" enemy piece to their own color. A piece is considered to be "vulnerable" if it has no empty adjacencies, and it touches more enemy than friendly pieces.

The goal of the game is to connect all three sides of the board with a connected group of your own pieces. Corners count as being part of both edges.

Myramid is inspired by the game Morphos by Luis Bolaños Mures.
