OMM International Mahjong Card

Say hello to the International Mahjong Card (IMC) — your go-to guide for modern Mahjong play. Designed to bring unity and clarity to the game, the International Mahjong Card is perfect for every player, including those with color-vision differences, ensuring that Mahjong is accessible to all.

In creating this card, we set out to bring together the very best elements of global Mahjong traditions. We drew inspiration from Wright-Patterson’s revered publication, released every five years, giving a nod to terminals 11’s and 99’s, and one day hope to incorporate their beloved flower bouquet bonus — awarding extra points for numbered 1–4 flowers. At the same time, we’ve honored signature aspects of Riichi play from Japan, as well as the classic Pungs and Chows found in traditional Chinese Mahjong. The result is a thoughtfully blended card that celebrates Mahjong’s rich cultural heritage and unites players across styles and borders.

Ordering is simple, shipping is reliable, and our friendly support team is always just an email away. You’ll find helpful FAQs on our website and a dedicated Facebook page for real-time updates and community discussions.

For today’s players using blanks and modern variations, the IMC serves as a trusted standard — bringing everyone together with one consistent way to play.

The International Mahjong Card will be released annually at the beginning of each year. Orders placed now will begin shipping after January 2, 2026, complete with tracking and easy-to-reach customer service.

Best of all, 15% of every sale goes directly to charities that support Alzheimer’s research, awareness, and the search for a cure — a cause close to our hearts.

The future of Mahjong starts here.
