Terms of use.
By using RTP Lab you agree to the terms below. If you don't agree with them, please don't use the site.
Last updated: August 2026
Demo and educational use only
RTP Lab provides free calculators and simulators for provably-fair crypto casino game mechanics. Every simulator runs on virtual demo credits — no real money is wagered, deposited, or paid out anywhere on this site. Nothing here processes a real bet, and nothing here is a gambling service.
You must be 18 or older
This site discusses gambling mechanics and is intended for users aged 18 and older only. By using RTP Lab you confirm you meet this requirement.
Not Stake, BC.Game, Rainbet or Roobet
RTP Lab is an independent, unaffiliated project. Platform names are used only to describe and compare publicly-cited game mechanics for informational purposes — we're not sponsored, endorsed, or paid by any platform we discuss, and we don't carry affiliate links or referral codes. All trademarks belong to their respective owners.
Figures are best-effort, not guaranteed
Every formula and table on this site is computed and cross-checked using the methodology described on the Method page, and platform-specific figures are sourced from publicly cited data. Platforms can change their own tables, edges, and terms at any time without notice, and where public sources genuinely disagree, this site says so rather than asserting a single number. Nothing here should be treated as a guaranteed or currently-live figure for any specific platform — always confirm directly with the platform in question before relying on a number for real-money decisions.
Provided "as is," no liability for reliance
RTP Lab is provided free of charge, "as is," without warranties of any kind, express or implied. To the fullest extent permitted by law, RTP Lab and its operators aren't liable for any loss or damage arising from use of this site or reliance on any figure, calculation, or simulator published here — including decisions made about real-money gambling on any third-party platform.
This site doesn't encourage real-money gambling
RTP Lab exists to explain the math behind these games, not to encourage anyone to gamble. Every house-edge figure published here is, deliberately, a reminder that the house wins in the long run at every game and every target. If gambling stops being fun, resources like BeGambleAware.org can help.
This page may be updated
These terms may be revised from time to time; the "last updated" date above will change when they are. Continuing to use RTP Lab after an update means you accept the revised terms.
