Game Creation should be

Easy and Enjoyable

We are dedicated to create a set of AI and block-based tools that is easy for everyday users, so everyone can customize their digital extended reality. If you enjoy playing sandbox, building your own virtual world, and earning prizes from your creativity, then you came to the right place.


We designed our entire system to be intelligent. We are working on an enormous AI system that can automate creation task and make game creation more accessible. In the future updates, you will be able to ask AI to turn your house into a tropical forest. Not only for the creation, we will bring more AI magics to 3D like style transfer, super resolution, and personalization.

not monopolized

We believe the digital extended world is open and not monopolized. All creators gain full control of their creations, but not company. ST's Fractional Copyright Infrastructure allows anyone to manage intellectual properties they own, licensing to the major digital world, and earn the royalty.

Materialized SDF Rendering Engine (MatEngine)

All experiences are powered by our highly compressive 3D structures that support play-to-build on all devices including mixed reality. In the future versions, the game scene will interact with real-world physics and chemistry, be fully destructible, and be equipped with ray tracing, enabling much more game plays.

ST Generative AI Engine

Here's the magic. Your creation can be learned by artificial intelligence. We will deliver ST AI Engine in the future, potentially enabling personalized level generation, 3D super-resolution, and 3D model guessing, upgrading the creating and playing experience to a whole new level.

Fractional Copyright (Postponed)

This is not an NFT scam or investment vehicle, instead an actual technology based on blockchains. Creators can manage their intellectual properties all-in-one platform. A single production can be contributed by and owned by thousands of independent creators without a team structure, enabling the creation of infinite open worlds in the future.
