OpenRGS is the remote gaming server infrastructure that powers every Pragmatic Play slot title. This page explains what an RGS is, how Pragmatic Play uses it to distribute games to operators, and why it matters for players checking RTP figures at UK-licensed casinos.
What OpenRGS Is
A Remote Gaming Server is the centralised system where all game logic, math models, and RNG outcomes are stored and processed. When a player spins a slot, the browser displays only the visual front end. Every calculation – bet, outcome, win value – is computed on the RGS and returned to the screen in real time. Pragmatic Play operates its own proprietary version of this infrastructure, through which all 500+ titles in the catalogue run. Operators connect once via a single API and access the full portfolio without building separate connections for each game.
RTP Configuration
Pragmatic Play makes multiple RTP configurations available for most titles. Gates of Olympus, for example, is available at 96.50%, 95.51%, and 94.50%. The operator selects which variant to deploy via the OpenRGS dashboard. This is applied server-side and is not visible or adjustable by the player. Because of this, the same slot can return a different percentage at two different casinos running the same platform.
The only way to confirm which variant is active is to open the in-game information panel before any spin. This panel pulls the live configuration directly from OpenRGS and displays the exact RTP for that session at that specific casino. The figure shown reflects the operator’s chosen setting, not a published default.
Certification and Compliance
OpenRGS is the primary audit point for the UK Gambling Commission and the Malta Gaming Authority. Before any title goes live in a regulated market, the RGS is independently tested by laboratories including eCOGRA and iTech Labs. These audits verify RNG fairness, RTP accuracy, and tamper-proof game log storage. Every bet and win across any Pragmatic Play title is recorded in real time on OpenRGS, forming the legal audit trail required under UKGC licence conditions.
What This Means for UK Players
Every Pragmatic Play slot at a UKGC-licensed casino runs on certified, audited infrastructure. The RNG has been independently verified. The RTP shown in the in-game panel is the figure actually applied to that session. For titles where the gap between the highest and lowest available RTP variants exceeds two percentage points, checking the panel before playing has a direct effect on the expected cost of play over time. The check takes under ten seconds on both desktop and mobile.
