Every Otto component was designed as part of a single system. The tile palette matches the mat. The racks complement the tiles. Nothing was designed in isolation, and nothing looks like it came from somewhere else.

Join the WaitlistMost Mahjong sets are assembled — tiles from one manufacturer, mat from another, racks sourced separately. Otto was designed the other way: every piece decided together, in the same visual language, with the same material logic. The result is a set where everything on the table belongs there.
Designed to be handled, not displayed. Recessed engraving with paint infill on every face — not flat UV printing — means the iconography has depth and the surfaces stay true over time.
Three-layer acrylic construction. Solid color backs stamped with the Otto mark using engraved infill. Every tile face designed within a restrained palette — moody, architectural, and consistent across all 160 pieces.
Sized for four players and designed to anchor the table, not decorate it. The mat is a surface first — cushioned, non-slip, and durable enough for regular use — designed in the same palette as the tile set.
Stored in a mat sleeve carrier that keeps it rolled clean. Designed to feel at home whether you're playing on a dining table or a dedicated game table.
Designed as furniture, not accessories. Solid walnut with a satin oil finish, rounded radii, and a refined brass inlay for the Otto mark. Heavy enough to feel permanent on the table, refined enough to look intentional.
Deliberately differentiated from the acrylic and tortoise shell racks that dominate the market. The walnut brings the same material warmth as the rest of the interior — because the racks are part of the room, not just the game.
One card per player. Designed to sit in your hand during a live game and answer the question "wait, can I do that?" in under five seconds. Not a rulebook — a panic-prevention tool for the moments when the game is moving and someone needs a fast, confident answer.
Includes Joker rules, calling rules, dead hand causes, and Charleston basics on one side. The NMJL card decoder — suit colors, set types, parenthetical notations, and exposure rules — on the other.
The complete Otto system — tiles, mat, racks, and reference cards — designed to arrive as one cohesive object. Bundle pricing will be available at presale launch for waitlist members.
