Our Methodology

Editorial independence

We rank and recommend bets, games, and operators strictly by their true mathematical and consumer value: never by what earns us the most. Where your interest and our revenue could diverge, we side with you and disclose the tension.

We earn affiliate commissions, and some partners pay based on how much referred players wager. That creates a built-in conflict. Our answer is a hard rule: we never steer you toward higher-house-edge games or bets to earn more. Our odds content consistently points to the lowest-edge, best-value options.

How we review operators

Every operator we feature is scored on a transparent, consumer-protection-weighted rubric:

• Trust & transparency (ownership, track record, complaint history)
• Redemption / prize process (requirements, speed, friction)
• Responsible-play controls
• Promotions: clarity & honest value
• Eligibility & availability by state
• Customer support, and payment options

And we label our level of experience with each, honestly:

• Personally tested: we signed up and used it.
• Document-reviewed: assessed from official terms and credible sources, not firsthand.
• Not yet tested: listed for comparison, not yet assessed in depth.

We never imply firsthand experience we don't have.

How our simulators work

Every simulator on the site shows its work:

• The exact game rules being modeled, and any assumptions
• The mathematical basis (and, where useful, the derivation)
• The engine version and its test/validation status
• A "last reviewed" date
• Reproducibility, where practical, you can re-run the same result

For our table and card games: Blackjack, Roulette, Baccarat, Craps, Casino War, Three Card Poker, Four Card Poker, Let It Ride, Mississippi Stud, Spanish 21, and Double Down Madness; our simulations reflect the games' true, knowable odds. Slots are different: real slot machines use proprietary, undisclosed math, so our slots feature is an illustrative model of how RTP and variance behave, clearly labeled, never presented as the odds of any real machine.

Independently reviewed

Sometimes complex math is easy to get subtly wrong, so we don't just take our own word for it. Our core simulators (Blackjack, Roulette, Baccarat, Craps, and the Slots model) went through independent adversarial review: a separate AI system that didn't build it checks the math, runs the full automated test suite, and actively tries to break it: out-of-sequence inputs, edge cases, and unstated assumptions. For Blackjack we ran five such review passes, fixing each real finding with a regression test and re-reviewing until it held up. This is a software code-and-methodology review by a separate model, not an audit or certification by a credentialed third party, and we keep any unresolved limitations visible rather than hiding them.

The later table games below add another layer: their odds are exactly computable, so we compute the whole game in full, exhaustive enumeration or backward induction over every possible deal, and unit tests assert the result matches the known published edge. Each has also been independently reviewed for math and code correctness.

We're also deliberately careful with the word "exact." Our default Blackjack model is mathematically exact for the rules it states; where a figure is a close estimate instead, as with some finite-deck and live-dealer variants: we label it that way, and we never round an approximation up into a guarantee.

Blackjack validation (current): engine 0.4 · 137 fast regression tests, 4 high-sample validation tests, and a regenerated 240-rule finite-edge table; last independently reviewed 2026-06-21 (5 review passes).

Roulette validation (current): engine 1.0 · 43 regression tests; last independently reviewed 2026-06-23 (3 review passes). Independently reviewed for math and code correctness; every reported finding was addressed and regression-tested.

Baccarat validation (current): engine 1.0 · 48 regression tests; last independently reviewed 2026-06-23 (2 review passes). Independently reviewed for math and code correctness; every reported finding was addressed and regression-tested.

Craps validation (current): engine 1.0 · 57 regression tests; last independently reviewed 2026-06-24 (1 review passes). Independently reviewed for math and code correctness; every reported finding was addressed and regression-tested.

Slots validation (current): engine 1.0 · 84 unit tests; last independently reviewed 2026-06-29 (1 review pass). Independently reviewed and PASSED (D-008). An independent reviewer re-derived every preset's RTP and volatility from the disclosed ranges, confirmed the outcome space tiles exactly, and verified the simulator's integer-cent accounting; the build-time integrity gate re-checks the figures on every deploy. Note that, unlike the four games above, this is our illustrative model; the figures are exact for the model it defines, never the odds of any real machine.

Exactly-computable table games

These games are verified by exhaustive computation and independently reviewed for correctness. Each line shows the method, the per-engine test count, and the published edge(s) the tests assert against, last checked July 2026.

Casino War validation: exact closed-form odds · 14 unit tests, asserting the published war 2.88%, surrender 3.70%, Tie side bet 18.65%; independently reviewed 2026-07-22.

Three Card Poker validation: exhaustive enumeration (exact) · 24 unit tests + 1 high-sample test, asserting the published Ante-Play 3.37% (element of risk 2.01%), Pair Plus 7.28%; independently reviewed 2026-07-22.

Four Card Poker validation: exact enumeration (Aces Up) + published, Monte-Carlo-verified (Ante-Play) · 14 unit tests + 1 high-sample test, asserting the published Aces Up 3.89% (exact); Ante-Play ≈3.40%; independently reviewed 2026-07-22. The Ante-Play joint space is too large to enumerate, so that figure is the published simple-strategy edge, Monte-Carlo-verified: labeled as such, not presented as exact.

Let It Ride validation: exact backward induction · 16 unit tests + 1 high-sample test, asserting the published house edge 3.51% (element of risk 2.86%); independently reviewed 2026-07-22.

Mississippi Stud validation: exact backward induction · 18 unit tests + 1 high-sample test, asserting the published house edge 4.91% (element of risk 1.37%); independently reviewed 2026-07-22.

Double Down Madness validation: derived strategy, seeded Monte-Carlo vs three published paytable edges; dealer/side-bet math computed exactly · 22 unit tests + 4 high-sample tests, asserting the published V1 0.95% (element of risk 0.61%), V2–V3 2.07% (1.32%), average final wager 1.57 units, Push 22 side bet 11.76%; independently reviewed 2026-07-23. The dealer model checks out almost exactly: our independently computed P(dealer makes exactly 22) is 0.07357 against the 0.07353 implied by the published side-bet edge. The main game, measured over 6 seeds × 1M hands, lands on the published Version 1 figure within noise (0.986% ± 0.038 vs 0.95%, average wager 1.57 exactly) and within 0.08 points on Versions 2–3; the residual is the derived strategy's approximation, in the conservative direction (it can only overstate the house edge).

Spanish 21 validation: derived strategy, seeded Monte-Carlo vs the published edge; exact settlement & side bet · 18 unit tests + 2 high-sample tests, asserting the published S17 0.40% / H17 0.76% (Monte-Carlo); Match the Dealer 3.06% / 2.99% (exact); independently reviewed 2026-07-22. The strategy is derived in-engine (not transcribed) and it independently reproduces published chart lines as a self-check; the main-game edge is a Monte-Carlo estimate against the published figure, while settlement and the Match-the-Dealer side bet are exact.

Video Poker validation: full enumeration (exact): all C(52,5) deals × 32 holds, best hold kept · 54 unit tests + 1 high-sample test, asserting the published 12 schedules across three families: full-pay 9/6 JoB 99.5439% down the ladder to 6/5 at 94.9961%, Bonus Poker 8/5–6/5, and Deuces Wild full-pay 100.7620% / NSUD / Illinois; every published figure reproduced by our enumeration at 6+ decimals; independently reviewed 2026-07-27. Independent adversarial review (D-008): a from-scratch second implementation matched the evaluator on all 2,598,960 hands in both modes with zero mismatches, matched hold EVs to 1e-10, and reproduced the three exact returns to ~1e-9. CI also holds the fast core equal to a direct-enumeration reference solver on every hold of sampled hands, to nine decimals.

Blackjack Switch validation: derived strategy, seeded Monte-Carlo vs the published edge; Super Match computed exactly; an in-engine exact solver anchors the strategy itself · 36 unit tests + 1 high-sample test, asserting the published base game 0.58% (6 seeds x 500k rounds), dealer-22 rate 7.3536%, Super Match 2.55% (exact enumeration of all 387,278,970 four-card combinations); independently reviewed 2026-08-08. Two independent adversarial gates (D-008), and the first one FAILED the module: a defect in the hand-value routine made the dealt dealer stand on soft 17s the rules require it to hit, moving the house edge 0.061 points and manufacturing phantom dealer-22 pushes. A second reviewer re-derived every fix from scratch rather than trusting the remediation, matching a from-scratch reference across 1,111,110 ordered hands with zero mismatches, and held the module again until its own record stopped claiming checks that did not exist. Honest limits, carried forward: the main-game edge is a Monte-Carlo estimate, not an exact solve; our switching strategy computes the exact value of both arrangements, so a human using the published point count gives up roughly 0.08% more (advanced) or 0.17% (simple); and the cost of those two published methods is cited, not derived - no code path here exercises them.

DJ Wild validation: exact enumeration of all 2,869,685 five-card deals for hand frequencies and all four Trips edges; published strategy, seeded Monte-Carlo for the base-game edge · 22 unit tests, asserting the published 3.47% of ante / 1.73% of both required bets (element of risk 1.02%), average wager 3.39x ante, tie rate 0.0114%, Trips 0.59% / 1.19% / 3.16% / 6.16%; independently reviewed 2026-08-08. Independent adversarial gate (D-008), PASS: the reviewer rebuilt the evaluator from scratch and swept the whole deal space, finding zero category mismatches across all 2,869,685 hands, verifying the hand ordering as a strict order-isomorphism (so ties and kickers are exactly right rather than approximately), and re-deriving all four Trips edges independently. Their own strategy implementation agreed with ours on every hand, giving an exact raise rate of 0.693235 and an average wager of 3.3865x against the published 3.39. The base-game edge has no exact solver here - it is a Monte-Carlo estimate bound to the published figure within three standard errors, and that limit is stated rather than glossed. Two constants that a live page could otherwise drift away from, the full hand-frequency table and the strategy's raise count, are recomputed and pinned by the test suite on every run.

Crapless Craps validation: exact closed-form bigint rationals for every bet on the felt; the seeded Monte-Carlo simulator only validates against the solver, never the reverse · 42 unit tests, asserting the published pass line 5.3824% (exactly 373/6930, from P(win) 6557/13860), place 2/12 7.143% (1/14), place 3/11 6.25% (1/16), place 6/8 1/66 unchanged from regular craps, free odds exactly 0% on all ten points, and a pass flat backed with the full 1-2-3-4-5 ladder at 1.327% of total action (373/28105); independently reviewed 2026-08-07. Independent adversarial gate (D-008), PASS with no math defects: the reviewer re-derived every headline figure from first principles and drove the roll-resolution routine through an exhaustive 36-outcome harness in both this module and classic craps, confirming the two settle props identically and that the props are purely additive. One wording item was BLOCKING and was fixed in the gate commit - settlement text inherited from classic craps told the player the line "wins on the come-out (7 or 11)", which is false here where only the 7 wins, so crapless now exports its own reason text with a test pinning that no string ever claims "7 or 11". Honest limits: the 1-2-3-4-5 odds ladder is floor-report provenance from a single Hard Rock Hollywood visit on 2026-08-06, one step below the photo-confirmed layout figures, and the 11:2 / 11:4 crapless place schedule matches the published standard but is not visible in the photos - both are labeled that way in the module rather than presented as evidenced. Session mode deliberately reports no analytic anchor, because a slip of several bets has no single edge to converge to.

Big Six Wheel validation: exact enumeration of all 54 pockets, as reduced integer fractions with floats only at presentation · 22 unit tests, asserting the published $1 11.11% (1/9), $2 16.67% (1/6), $5 and $20 both 22.22% (2/9), $10 18.52% (5/27), and the two specials priced by schedule at 24.07% (13/54) for 40:1, 14.81% (4/27) for 45:1, and 11.11% (1/9) for 47:1; independently reviewed 2026-08-08. Independent adversarial gate (D-008), PASS with no functional defects: the reviewer re-derived all eight edges from first principles, then walked the literal wheel array pocket by pocket in a brute-force enumeration that bypasses both the pocket-count helper and the solver's formula, so a shared bug in either could not hide. Every figure is pinned in the tests as an exact fraction string rather than a decimal tolerance, so a payout typo cannot slip through on rounding. Honest limits: the payouts are photo-confirmed on the Seminole Hard Rock Hollywood layout, but the 24/15/7/4/2/1/1 pocket composition is the published standard US wheel cited to the Wizard of Odds rather than something we counted - our photos are too angled, our enumeration reproduces every published figure exactly from that composition, and strong indirect confirmation is not the same as having counted the wheel. The gate covered the math layer only, as no UI existed at review time.

Comps and casino loyalty programs

Our comps tools answer a different question than the game simulators: not "what are the odds?" but "what is my play worth back to me?" Every comp is driven by theoretical loss, average bet × decisions per hour × hours × house edge, so the calculators reuse the same known house edges from our game engines. That part is exact for the rules you select.

The uncertainty lives in the loyalty-program data, not the arithmetic. Earn rates, point values, and reinvestment percentages vary by property, tier, and promotion, and programs change them without notice. So we treat every program figure as an estimate: each is dated, labeled by how confident we are, and fully overridable; you can plug in the exact number your host or player's-club card quotes. The tool calculates; it doesn't claim authority over a casino's private rates.

We label loyalty figures the same honest way we label everything else:

• Official: published by the operator (e.g. Club Royale's slot and video-poker earn rates).
• Player-verified: confirmed firsthand on a recent visit but not officially published (e.g. Club Royale's points-to-FreePlay conversion). We say so, default to the verified figure, and flag that it varies.
• Community-representative: typical values players report that change month to month; shown as a starting point, with the operator's own current document linked as the source of truth.

The headline number every comp tool leads with is deliberately the honest one: net expected cost: your theoretical loss minus the comp value. For realistic rates it stays positive. A comp reduces the cost of play you were going to do anyway; it does not turn a negative-expectation game into a winning one, and a "free" room or cruise earned from scratch has a real price we show you up front. Because comps are about brick-and-mortar and cruise casinos, nothing on these pages links you to a place to gamble: no operator sign-ups, no casino affiliate links, no referral codes. That is the rule and it has not moved. You may see a card for one of our own books, which is a book, not a casino, and is labelled as ours wherever it appears.

Comps math (current): the theo, points, tier, and "play needed" calculations are deterministic closed-form arithmetic, not Monte-Carlo simulations, verified by unit tests with worked examples locked to exact values. The accuracy risk is in the program data above, which is dated (currently July 2026) and user-overridable. For our cruise coverage, Royal Caribbean's Club Royale certificate thresholds are taken directly from the monthly offer flyer, which the calculator links.
