RTP Game Audits
Answer: This hub collects RTP and fairness audits for casino Originals and zero-edge games covered on 100RTP.games. Each game is reviewed by its payout model, house edge claim, allowance status, provably fair verification path and unresolved audit caveats.
100RTP.games does not list games by popularity alone. The focus is whether a game’s return claim can be checked. Simple probability games such as Dice, Mines and Plinko can often be audited from formulas and visible multipliers. Slot-style and strategy-dependent games require deeper paytable, rule or feature analysis.
Use this page to compare which games have the strongest mathematical evidence, which rely on live paytable checks, and which still have unresolved verification gaps. A game can be provably fair and still have a house edge, so RTP auditing and seed verification are treated as separate checks.
Audit framework
How to Read These Game Audits
Every game is classified by the type of evidence needed to support its RTP or zero-edge claim.
Formula audit
Used for games where probability and payout can be checked directly.
Used for games where probability and payout can be checked directly.
Paytable audit
Used when every payout row must be multiplied by its probability.
Used when every payout row must be multiplied by its probability.
Strategy audit
Used when player decisions change the theoretical return.
Used when player decisions change the theoretical return.
PF check
Used to confirm completed outcomes from server seed, client seed and nonce.

Allowance check
Used when 100% RTP applies only inside a capped wager window.
Used when 100% RTP applies only inside a capped wager window.
Game Audit Status
| Game | Main Audit Type | Evidence Level | Main Caveat |
|---|---|---|---|
| Duel Dice | Fair multiplier formula | Strong | Allowance status and extreme slider rounding should be checked live. |
| Duel Mines | Combinatorial multiplier math and board verification | Strong | Displayed multiplier and active allowance state must match the formula. |
| Duel Crash | Auto-cashout probability and bust-point verification | Strong at target-math level | Full crash distribution and allowance state still matter. |
| Duel Plinko | Binomial lane probabilities and multiplier-table RTP | Strong probability model | Each rows/risk table must be summed separately. |
| Duel Keno | Hypergeometric odds and paytable sum | Strong probability model | Live paytable still needs row-by-row RTP confirmation. |
| Duel Blackjack | Rules, strategy and edge-return treatment | Medium | RTP depends on live rules, deck model and correct strategy. |
| Duel Video Poker | Paytable and optimal strategy audit | Medium | Exact live paytable must be extracted before confirming RTP. |
| Castle Roulette | 48-segment wheel distribution and payout EV | Medium | Live outcome verification and exact RTP mechanism still need confirmation. |
| Groomer’s Van | Slot rules, feature model and PF caveats | Rules-supported, not fully grid-proven | Full grid probability audit and Bonus Buy trigger verification remain open. |
| Duel Beef | Step multiplier / mission-style audit | Operator-stated / pending deeper audit | Not part of the clearest simple fair-play formula group; needs separate verification. |
Formula-Driven Games
Formula-driven Originals have the cleanest audit path. Their probabilities can be calculated from visible settings, then compared with the displayed multiplier, paytable or target probability. These games still need allowance and provably fair checks, but the RTP math is relatively transparent.
Strategy-Dependent Games
Blackjack and Video Poker cannot be judged by headline RTP alone. Their return depends on rules, paytable, deck model and player decisions. A fair-return claim is only meaningful if the live rules and optimal strategy assumptions are known.
Slot-Style and Live-Style Games
Slot-style and live-style games require more caution. Their rules may support a high or fair return claim, but a complete audit needs feature-level, wheel-level or grid-level verification rather than a single formula.
What RTP Audits Can and Cannot Prove
| Check | What It Can Prove | What It Cannot Prove |
|---|---|---|
| Multiplier or paytable audit | Whether the visible payout model matches fair or reduced-return math. | Whether the random outcome was generated correctly. |
| Provably fair verification | Whether a completed outcome matches disclosed seed data. | Whether the game has 100% RTP or no house edge. |
| Allowance check | Whether a fair-play cap or post-cap state may affect the current round. | Whether the casino is safe overall. |
| Strategy audit | Whether optimal decisions are required to approach theoretical return. | Whether a casual player will actually receive that return. |
| Platform review | Licensing, withdrawals, KYC and operational risk context. | Exact fairness of every individual round without seed-level data. |

Bottom Line
The strongest game audits on 100RTP.games are the ones where probability, multiplier and outcome verification can be separated clearly. Dice, Mines, Crash, Plinko and Keno have the most transparent math. Blackjack and Video Poker need strategy and paytable context. Groomer’s Van and Castle Roulette need more caution because their feature models and live-style mechanics are harder to verify end to end.
The correct way to use this hub is not to assume every listed game is equally proven. Start with the evidence level, then check the live allowance state, the payout model and the available provably fair data before relying on any 100% RTP claim.
