Story & visual language
A memory, culture, audience or atmosphere becomes the starting point.
13-su Custom · Original Mahjong development
Your idea.
One original
Mahjong world.
You do not need a finished brief. Bring us a story, a mood, a market or simply a question—we will help shape it into a complete, production-ready Mahjong collection.
Every project can begin unfinished.

See an idea take shape
Original work is a process, not a preset.
A complete tile family
Dots, bams, craks, winds, dragons, flowers and jokers are developed as one world.
Material & production
Artwork, proportions, layers and production requirements are considered together.
Begin your way
Two ways to start.
No perfect brief required.
