Key Takeaways
- House edge = 100% − RTP. A 92% RTP game carries an 8% house edge.
- Every jurisdiction sets its own maximum — what passes in one market fails in another.
- Use the check to confirm a game fits the target market before certification.
Illustrative estimates based on operator-provided inputs. Actual results depend on market conditions, player behavior, and regulatory requirements. Licensing and compliance in your market are your responsibility — confirm your local rules.
How This Calculator Works
House-edge compliance is a compare problem: game house edge vs jurisdiction maximum. This tool lets a licensed operator check a game's edge from two inputs — the game's RTP (or house edge) and the market's published maximum.
Everything runs in your browser. No inputs are transmitted or stored.
The Model
house_edge = 100% - RTP
status = house_edge <= max_allowed ? PASS : FAIL
headroom = max_allowed - house_edge
The headroom tells you how much margin you have before a game breaches the cap — useful when a math model drifts during recertification.
A Worked Example
Game RTP 94% (house edge 8%), jurisdiction max 15%:
- House edge = 100 − 94 = 8%
- Status = PASS
- Headroom = 15 − 8 = 7%
Same game in a market with a 5% cap FAILS — the game cannot deploy there without a different math model.
Check Before You Certify
Certification costs real money; screening first avoids submitting a game that cannot pass. Confirm the official limit for your market via the compliance hub, then verify the math model with the RTP verification calculator.

Frequently Asked Questions
What is house edge?
House edge is the mathematical advantage the game holds over the player, expressed as a percentage. It equals 100% minus the return-to-player (RTP). An RTP of 94% means an 8% house edge.
Where do I find the jurisdiction maximum?
Each regulated market publishes its own cap in gaming regulations — often 5% to 15% depending on game class. The value you enter must come from the official source for your deployment market; we do not publish limits because they change and vary by jurisdiction.
Does passing this check mean I am certified?
No. This is a pre-check against a limit you supply. Certification still requires lab testing (GLI, BMM or the local lab) scoped per market and per order. Use this to screen games before submitting.
Does GOLDPRIME set house edge?
We build to the certified configuration your market requires. The house edge of a delivered game is set by the approved math model for that jurisdiction — confirmed during certification.
