One API. Every game.
Server-authoritative, provably-fair titles with configurable RTP, multi-currency and a seamless wallet.
One platform, every service.
Games players trust, operators can tune.
Each title runs on our RGS: outcomes are decided server-side and every round can be verified by the player. Try them live.
We are Three Tails.
An independent studio building original, server-authoritative casino games — and the platform that runs them. We keep the maths honest: every outcome is decided on our servers and is provably fair, and integration is built to be effortless for the operators who licence us.
Seven titles are live today, with more in production and a provider platform that lets operators tune RTP, currency and limits per market from a single place.
Everything an operator needs, one integration.
The player's browser never decides the result — our RGS does, and hands back proof. Better for players, cleaner for you to certify and run.
Integrate once.
Launch every game.

Tune per market
Set RTP, limits and currency per operator — inside each game's certified band.

Latest releases and what we're building next.
Built to be certified.
We engineer for the standards regulators and operators expect — so certification is a step, not a rebuild.
