//about
A Tallinn software studio, registered in 2021
3S Game Studio OÜ was entered in the Estonian e-Business Register on 28.07.2021 under registry code 16279375, with computer programming activities (EMTAK 62011) as its principal activity. We engineer software, engine systems and infrastructure for companies.
The client owns the work
Bespoke code is written in the client’s repositories and assigned to the client under the agreement. Documentation and runbooks are deliverables, so the system never depends on us to keep running.
Claims we can show you
We publish no client logos, no project counts and no uptime numbers. Targets are agreed in writing per engagement and measured with your own tooling.
Engine skills, business software
Real-time engines force discipline about frame budgets, memory and determinism. We bring the same discipline to back-end systems, and the same honesty about trade-offs.
Businesses only
We work under written agreements with companies and public bodies. We do not provide technical support to consumers or sell software to the public.
