This page is the central index for our game audits. The goal is not just to list games, but to separate direct mathematical verification from operator-stated claims and pending checks.
For each game, we ask the same core questions: what is the return model, how is the payout calculated, can the outcome be reproduced through provably fair verification, what limits apply, and what still needs to be checked?
Evidence note: Not every game has the same audit quality. A Dice multiplier can be checked in seconds. A slot-style game with cascades, free spins and bonus buys requires a deeper probability model. Evidence levels are shown on each audit page where relevant.
Game Audit Index
Dice
Adjustable win-chance game where the fair multiplier is simply 1 / probability. The cleanest test case for visible fair pricing.
- Audit focus: multiplier formula, win chance, post-allowance pricing
- Verification: seed-based roll reproduction
- Evidence level: strong formula-level auditability
Crash
Rising multiplier game where a fair auto-cashout target should follow the 1 / x reach-probability model.
- Audit focus: crash distribution, auto-cashout math, bust-point verification
- Verification: seed-based outcome check where the platform mode is known
- Evidence level: strong model plausibility, full distribution audit still important
Mines
5×5 grid game where each cashout multiplier can be checked against exact survival probability.
- Audit focus: combinatorial multiplier formula, mine layout, cashout probability
- Verification: hidden board reconstruction from seed data
- Evidence level: strong formula-level auditability
Plinko
Ball-drop game where lane probabilities follow the binomial distribution and RTP depends on the multiplier table.
- Audit focus: lane probabilities, row settings, risk levels, weighted-average return
- Verification: path verification plus payout-table audit
- Evidence level: probability model verified; full lane table should be checked live
Keno
Number-draw game where match probabilities are calculated with the hypergeometric distribution.
- Audit focus: 40-number draw, match probabilities, paytable expected value
- Verification: draw reproduction plus paytable calculation
- Evidence level: probability model verified; live paytable audit required
Blackjack
Strategy-dependent card game where return depends on rules, deck model, decisions and any edge-return treatment.
- Audit focus: ruleset, deck model, basic strategy, effective return
- Verification: card-generation model and hand outcome checks
- Evidence level: partially verified; exact live rules and card model still matter
Castle Roulette
Live multiplier wheel game with a reported 48-segment distribution across 2x, 4x, 8x, 16x, 24x and 48x tiers.
- Audit focus: segment distribution, EV per multiplier tier, live verification caveats
- Verification: claimed provably fair process, live seed-to-outcome audit still needed
- Evidence level: published wheel math is coherent; live PF pending
Video Poker
Reported Jacks or Better-style Original where RTP depends on the exact paytable and optimal hold strategy.
- Audit focus: paytable, Royal Flush payout, strategy dependence, deck verification
- Verification: full deck order and replacement-card queue
- Evidence level: operator-stated until live paytable is independently extracted
Groomer’s Van
Cluster-pay slot-style Original with tumble mechanics, free spins, multiplier symbols, 125x Bonus Buy and a 5,000x max win.
- Audit focus: rules-screen RTP, cluster paytable, multiplier distribution, Bonus Buy caveat
- Verification: complex grid and tumble verification; Bonus Buy trigger spin caveat
- Evidence level: rules-supported, full grid-probability audit pending
How We Classify Game Evidence
Each audit page uses a practical evidence framework. The goal is to avoid treating every marketing claim as equally proven.
| Evidence Level | Meaning | Typical Games |
|---|---|---|
| Strong formula-level auditability | The core payout formula can be checked directly from probability and multiplier values. | Dice, Mines, Plinko probability model |
| Paytable-dependent | The probability model is known, but the live payout table must be extracted and summed. | Keno, Plinko, Video Poker |
| Strategy-dependent | The theoretical return depends on player decisions and rule assumptions. | Blackjack, Video Poker |
| Implementation-dependent | The return model is plausible, but exact platform implementation and verification flow matter. | Crash, Castle Roulette |
| Complex slot-style audit | The game requires symbol weights, tumble behavior, feature frequency and max-win treatment to be fully modeled. | Groomer’s Van |
What We Check in Every Game Audit
- Return model: native fair pricing, hybrid return, post-cap pricing or reward-adjusted return.
- Payout math: multiplier formula, paytable, lane distribution, match probabilities or card rules.
- Variance profile: how frequently losses occur, how large wins can be and where volatility comes from.
- Verification path: whether results can be reproduced from server seed, client seed and nonce.
- Allowance status: whether the game uses a daily wager cap, per-bet limit or post-limit pricing.
- Open questions: what still needs live inspection, paytable extraction or full mathematical audit.
Simple Games vs Complex Games
Not every game is equally easy to audit. A simple probability game can be checked from one formula. A slot-style game needs far more information.
| Game Type | Audit Difficulty | Why |
|---|---|---|
| Dice | Low | Multiplier should equal 1 / win chance. |
| Mines | Low-medium | Cashout values follow combinatorial survival probability. |
| Plinko | Medium | Lane probabilities are easy; live multiplier table still needs summing. |
| Keno | Medium | Match probabilities are exact; RTP depends on the live paytable. |
| Crash | Medium | Requires correct bust-distribution formula and rounding model. |
| Blackjack | High | Rules, deck model and strategy quality all affect return. |
| Video Poker | High | Paytable and optimal strategy both matter. |
| Groomer’s Van | Very high | Slot-style grids, tumbles, feature triggers, multipliers and max-win caps require deeper modeling. |

Bottom Line
The Games section is where 100RTP.games separates easy-to-check formulas from claims that still need paytable, rule or implementation verification. Dice, Mines and Plinko are the clearest mathematical starting points. Blackjack, Video Poker and Groomer’s Van require more caution because player decisions, paytables or complex slot mechanics affect the result.
Use this hub as the map. Start with the game you actually play, then check its return model, verification path, variance profile and unresolved audit questions before trusting the headline RTP.
