Serenity Greens is no longer the only place to lose a golf ball. Tiny Mini Golf: Mystery Worlds adds three new map sheets to the base game, each built around a simple change to the familiar course geometry. Caravan Trails replaces the usual outer walls with desert sand, Buccaneer Splash spreads the course across two pirate ships connected by narrow planks, and Orbital Warps divides it between floating platforms linked by portals.
The core Tiny Mini Golf rules stay the same: players design courses for one another and then try to complete them in as few shots as possible, with stronger shots bringing more risk. The new maps change the routes and decisions rather than adding a heavy new layer of rules — sand can swallow overambitious shots, planks reward straight lines, and portals make distant spaces suddenly adjacent.
Mystery Worlds is slightly more advanced than Serenity Greens and is intended for players already familiar with the base game. The maps work with all multiplayer modes from Tiny Mini Golf and are designed to remain compatible with its other expansions.
