The Story

A New Chess for a New Era

Born from 1,000 years of Thai chess tradition. Forged with the precision of international play. Reimagined for the modern board.

For centuries, the world has known two great chess traditions: international chess with its 8×8 battlefield, and หมากรุกไทย (Thai chess) with its ancient elegance.

SiamChess is the first to honor both — and create something entirely new.

"A game where the Garuda flies, the Hanuman leaps across oceans, and every move tells a thousand-year story."

Played on a 10×10 grand board, SiamChess introduces four legendary pieces drawn from Thai mythology: ครุฑ (Garuda), ขุนพล (Warlord), ทมิฬ (Titan), and หนุมาน (Hanuman). Each has powers no chess piece has ever known.

This is not just a game. It is a cultural artifact for the digital age.

The Pantheon

Four Legendary Pieces

Each piece is born from Thai legend and designed with chess theory in mind. Powers that have never existed before, balanced for tournament-level play.
