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, Oh My Mahjong set out to bring together the very best elements of global Mahjong traditions. They 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.

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.
