RTP Testing for Fair Game Mathematics

Paytable analysis and statistical simulation confirm that every game, and every RTP configuration, returns exactly what it declares before it launches in each market.

Gaming Associates verifies the Percentage Return to Player of a game, confirming the expected portion of wagers returned to players over time matches its declared value. Game and software providers and game developers rely on this testing to confirm a game's mathematics accurately and early in development, while operators and aggregators may also require it when reviewing third-party content for their platforms

What Gets Evaluated

Our games testing methodology complies with all jurisdictions and involve but not limited to:

Theoretical Paytable & Weighting Review

Analysis of symbol distribution, paylines, scatter rules, and configuration parameters to calculate the baseline theoretical RTP.

Statistical
Simulation

Running simulated test rounds to measure how closely actual outcomes converge with the declared RTP.

Base Game vs. Feature Weighting

Isolating baseline payouts from features like free spins, multipliers, and jackpots to assess balanced risk distribution.

Volatility & Hit Frequency Profiling

Confirming a game's volatility and hit frequency match its documentation and design intent.

Multi-RTP Variants

Many games aren’t built with a single fixed RTP, they’re built with several configurable profiles, allowing the same title to run at different return percentages depending on where it launches.

Jurisdictions often set different RTP thresholds, and operators may prefer a different configuration for commercial reasons, meaning one game can serve multiple markets without needing a separate build for each.

What is Game Mathematics Assessment?

The calculation of game returns involves an exhaustive evaluation or simulation of all potential combinations. This process utilizes sophisticated algorithms to analyze payout tables provided by game developers, determining the theoretical return on investment (ROI or RTP return-to-player).

Frequently Asked Questions

What's the difference between theoretical and empirical RTP?

Theoretical RTP is calculated by a testing laboratory like Gaming Associates through analysis of a game’s paytable and configuration rules. Empirical RTP is observed through simulation or live data, confirming that actual outcomes align with the mathematical design.

Can a game's RTP be changed after certification?

In regulated markets, modifying RTP after release is typically restricted. Where a
change is made, an accredited testing laboratory like Gaming Associates generally
needs to re-certify the updated build before it goes live.

How does volatility relate to RTP testing?

Two games can share the same RTP while having very different volatility profiles, one paying out frequent small wins, the other rare, larger ones. An accredited testing laboratory like Gaming Associates evaluates both together to confirm the game behaves as intended.

Why is independent RTP verification required?

Independent testing, carried out by a conformity assessment body like Gaming Associates, gives regulators, operators, and players confidence that a game’s mathematics are accurate, free of hidden bias, and match what’s publicly declared.
