# Terxo — The 3D Tic-Tac-Toe Board Game

> Terxo is a unique 3D tic-tac-toe board game invented by Simone Paganoni in 2017. It features a wooden cube with 9 playable cells across 3 visible faces, combining physical craftsmanship with online multiplayer gameplay.

## What is Terxo?

Terxo is a strategy board game played on a 3D wooden cube. Unlike traditional tic-tac-toe which is played on a flat 3×3 grid, Terxo uses the three visible faces of a cube, creating a 9-cell playing field with unique spatial dynamics. Players place colored pieces (meeples) on the cube faces to form winning lines.
