Methodology

Why this page exists

This is the public record of how every operator on Crypto-Casinos.com is evaluated. We publish it for three reasons:

If a review on this site reaches a verdict, the reasoning behind that verdict traces back to this page. Where our findings disagree with operator marketing, this page is what we measured the marketing against.

What “crypto casino” means to us

We review operators that meaningfully use cryptocurrency or blockchain technology in their gambling products. Specifically, we cover:

We do not review conventional online casinos and sportsbooks that have no meaningful crypto offering, even if they accept one or two crypto deposit methods through third-party processors. Specialist coverage is the point.

A note on terminology: throughout this site, we use “crypto casino” as a shorthand. The same methodology applies to crypto-native sportsbooks, dice and crash sites, poker rooms, and other gambling formats within our scope, with category-specific tests added where relevant.

Our evaluation criteria

Every operator we review is evaluated across six areas. Each area contains specific tests; the results of those tests determine the verdict.

1. Licensing and legal standing

What we check:

License-issuing body, license number, and status, ownership transparency, jurisdictions served versus restricted, whether stated restrictions are actually enforced through geo-blocking, complaint history with regulators, and recognized mediation bodies.

What good looks like:

A license from a recognized authority, verifiable on the issuer’s public register; transparent corporate ownership; restricted jurisdictions enforced through working geo-blocks; clean or substantively addressed complaint history.

What fails:

Operating without any license, a license that cannot be verified on the issuer’s register, opaque or deliberately concealed ownership through shell structures, stated jurisdiction restrictions that are not actually enforced.

2. Web3 Authenticity Check

This section evaluates the gap between what an operator markets and what users actually receive. It is the most distinctive part of our methodology because the misrepresentation it tests for is widespread in this category and is what most other review sites do not check. It is documented in full in the next section.

3. Terms and player protection

What we check:

Bonus terms and wagering requirements, withdrawal limits and conditions, dormant account policies, identification verification triggers and processes, dispute resolution mechanisms, and the overall fairness and clarity of the T&Cs.

What good looks like:

T&C that are accessible, readable, and consistently applied; wagering requirements stated clearly with no hidden multipliers; withdrawal limits proportionate to deposit; identification verification disclosed before deposit; a real dispute process with a path to external mediation.

What fails:

T&C that contain unusually onerous clauses (e.g., maximum withdrawal caps that effectively trap large wins, dormant account fees that erase balances quickly); wagering requirements that are technically impossible to meet; identification verification triggered only at withdrawal in ways that can trap deposited funds; no functional dispute process.

4. Responsible gambling

What we check:

Deposit limits, loss limits, session time limits, reality checks, self-exclusion (both operator-level and integration with national programs where applicable), visibility of support service links throughout the site, exclusion of identified problem gamblers from marketing.

What good looks like:

A full suite of responsible gambling tools accessible without friction; visible links to support services from the registration and deposit flows; integration with national self-exclusion programs in markets where the operator is licensed to serve players.

What fails:

A meaningful absence of basic responsible gambling tools is, by itself, disqualifying. Marketing language that promotes gambling as a way to make money, targets audiences likely to include vulnerable users, or undermines self-exclusion tools is also disqualifying.

5. Operational quality

What we check:

Customer support responsiveness, payment processing reliability, site stability, mobile experience, withdrawal speed across multiple test cycles, support quality on substantive (not just procedural) queries.

What good looks like:

Support that responds within stated timeframes, with substantive answers from people who appear actually to work for the operator; consistent withdrawal performance across multiple test cycles; site stability and reasonable mobile experience.

What fails:

Unreachable support, scripted to the point of unhelpfulness, or that handles complaints by deflection; inconsistent or unexplained withdrawal performance; site instability serious enough to affect gameplay.

6. Game integrity

What we check:

For operators offering games marketed as provably fair, whether the implementation works (covered in detail in the Web3 Authenticity Check below); for operators using third-party game providers, the identity and standing of those providers; for in-house games, whether outcomes can be independently verified.

What good looks like:

Working provably fair implementations on the games where the claim is made; recognized game providers with public licensing; published RTP figures where applicable; smart contracts (where used) that are verified on-chain and audited by a credible firm.

What fails:

“Provably fair” marketing on games that do not actually implement it; in-house games with no verification mechanism; unverified or unaudited smart contracts presented as on-chain.

Web3 Authenticity Check

A significant share of operators marketed as “crypto casinos,” “Web3 casinos,” or “blockchain casinos” do not deliver the features that language implies. Some are honest hybrid operators that accept crypto deposits but otherwise function as conventional casinos — that is a legitimate model, and we do not penalize it when it is disclosed. Others market themselves as Web3-native while routing user funds, game outcomes, and account mechanics through conventional infrastructure, which contradicts their marketing.

The Web3 Authenticity Check is the part of our review process that tests marketing claims against actual implementation. Every operator we review is evaluated against the criteria below. Failures are documented in the review with evidence.

1. Payment rail verification

What we check:

Whether deposits and withdrawals are settled on-chain to operator-controlled wallets, or routed through third-party fiat processors, payment aggregators, or instant-conversion services not disclosed at deposit.

How we test:

We make real deposits and trace the destination on a block explorer. We make real withdrawals and time them, recording the transaction hash where one exists. We note any intermediary services involved.

What good looks like:

Direct on-chain settlement to operator wallets; withdrawals returned on-chain to the user’s specified address; transaction hashes visible in the user’s account history.

What fails:

Deposits routed through third-party processors are not disclosed before registration; withdrawals that the operator claims are “crypto” but are actually fiat off-ramps with delays, KYC triggers, or fees not stated in the deposit flow.

2. Custody model

What we check:

Whether user balances are held on-chain in a way the user can verify, in operator-controlled wallets, or in an internal ledger with no on-chain representation.

How we test:

We compare the operator’s stated custody model against what can be verified externally. For operators claiming non-custodial or on-chain balances, we verify that user funds are visible on-chain and that the user retains any cryptographic control.

What good looks like:

Clear, accurate disclosure of the custody model. If non-custodial is claimed, it is verifiably non-custodial. If custodial (which is the norm and not disqualifying when disclosed), it is described as such.

What fails:

“Non-custodial” or “your keys, your coins” language applied to what is in practice a standard custodial database balance.

3. Provably fair verification

What we check:

Whether games marketed as provably fair use a cryptographically sound seed-commitment scheme, and whether the verification tooling provided to users actually works.

How we test:

We play-test games, record the published seeds and outcomes, and run the operator’s own verification tool against them. We check which games are covered (operators sometimes apply “provably fair” branding sitewide while only a subset of games actually implement it). We assess whether the scheme is meaningful (commit-reveal with user-influenced seeds) or theatre.

What good looks like:

Working verification tools, user-influenced seeds, coverage stated accurately, and an independent audit of the implementation, where available.

What fails:

Verification tools that return errors, fail to verify legitimate outcomes, or aren’t actually exposed to users; “provably fair” claims applied to game categories where the mechanism doesn’t apply (e.g., live dealer games); implementations where the operator retains enough control over seed generation to make verification meaningless.

4. On-chain game and smart contract verification

What we check:

For operators offering games marketed as “on-chain,” “smart contract-based,” or “fully decentralized,” we verify the contract’s existence, verification status, and audit history.

How we test:

We locate the relevant contract on the appropriate block explorer. We check whether the source code is verified. We review any published audit reports and check whether the auditing firm has a credible track record. We test whether game outcomes actually settle on-chain.

What good looks like:

Verified contract source code; audit by a recognized firm with a public report; outcomes settled on-chain in a verifiable manner.

What fails:

“Smart contract games” with no identifiable contract; unverified contracts; audits by unknown or unaccountable parties; marketing language suggesting on-chain settlement when game outcomes are decided off-chain, and only deposits or withdrawals touch the chain.

5. Asset handling and conversion

What we check:

Whether deposited crypto is held in the deposited asset, instantly converted to a stablecoin or house token, or converted to fiat. Whether conversion spreads are disclosed.

How we test:

We deposit a known amount in BTC, ETH, or another supported asset and observe how the balance is represented. We check the rate against market spot prices at the time of deposit. We do the same on withdrawal.

What good looks like:

Balances held in the deposited asset, or transparent disclosure of any conversion with rates within market norms.

What fails:

Silent conversion to a house token or fiat balance, with conversion losses on both deposit and withdrawal that aren’t disclosed in advance.

6. KYC trigger transparency

What we check:

Whether identification requirements are disclosed before deposit, or only triggered at withdrawal in a way that can trap user funds.

How we test:

We review the registration and deposit flow for disclosure of identification requirements. We test the withdrawal flow at varying amounts to identify trigger thresholds. We note any cases where stated “no KYC” policies are contradicted in practice.

What good looks like:

Clear, upfront disclosure of identification thresholds and triggers; consistent application.

What fails:

“No KYC” or “anonymous” marketing contradicts the identification requirements at withdrawal, especially when the user has already deposited and played.

How Web3 Authenticity affects the verdict

Operators that pass these checks, or that do not market themselves as Web3 in the first place, are evaluated on our broader criteria. Operators that fail one or more checks while marketing themselves as Web3 are rated Not Recommended on those grounds, with the specific failures documented in the review. The verdict reflects the gap between what the operator markets and what users actually receive — not a judgment on whether the operator is legitimate in general.

Hybrid operators that openly describe themselves as crypto-accepting rather than crypto-native can still earn a Trusted rating if they meet our other criteria. The issue we flag is misrepresentation, not the use of conventional infrastructure.

How we test

The “Experience” leg of trust comes from real testing. For every operator we review:

Reviews based on desk research alone — without deposits, withdrawals, or hands-on testing — are not published as Trusted or Not Recommended verdicts. Where we have only partial testing access, the review states explicitly what we did and did not test.

The verdict system

We use two verdicts: Trusted and Not Recommended.

Trusted

Trusted means the operator meets our criteria across the categories above. It does not mean the operator is perfect, suited to every user, or guaranteed to remain Trusted in the future. Trusted verdicts are accompanied by an explicit statement of which user types the operator is most and least suited for.

Not Recommended

Not Recommended means the operator fails one or more of our criteria in a way material to readers. Common reasons include misrepresentation of Web3 features, opaque or onerous terms, ineffective responsible gambling tools, identification practices that trap deposited funds, or a pattern of unresolved player complaints. A Not Recommended verdict explains the specific failures with evidence and states what would change the verdict.

Better decisions instead of vague ones

Not Recommended is distinct from a claim that an operator is illegitimate, fraudulent, or operating illegally. We reserve characterological language for cases where we have evidence to support it, and even then, we prefer to describe what the operator does or fails to do rather than make claims about its character. The published review is the verdict; the page is the evidence.

We do not publish numerical scores (e.g., 9.2/10) because we do not believe the precision they imply is real. Binary verdicts force the editorial team to take a position; numerical scores allow it to avoid one.

Who reviews

All reviews are written by named members of our editorial team or named external contributors. Every review carries a byline linking to the author’s bio page, where their background and disclosures are documented.

Reviews of operators go through a two-person process: the primary reviewer conducts the testing and drafts the review; a second reviewer or editor verifies the testing record and signs off on the verdict before publication.

Reviewers do not write or edit reviews of operators with whom they have a current or recent commercial relationship. Where avoiding the conflict is not practical, the relationship is disclosed prominently in the byline, and a second reviewer signs off.

How often do we re-review

Trusted operators are re-reviewed on a 12-month cycle. Not Recommended operators are re-reviewed when material changes are reported to us or identified through ongoing monitoring (changes in ownership, license, terms, or technical implementation). Every review page displays a “Last reviewed” date and a “Next scheduled review” date.

Off-cycle re-reviews are triggered by:

When a re-review changes the verdict, the change is logged on the review’s update history and on the site-wide Corrections Log.

Right of reply

Operators who believe a review contains factual errors or misrepresentations can contact contact@crypto-casinos.com. We commit to acknowledging the message within 5 business days, reviewing the specific claims raised against our published methodology and evidence, correcting any factual errors we can confirm with a dated note, and publishing a response from the operator alongside the review where the operator wishes us to do so and the response is on the record.

We will not remove factual findings in exchange for commercial consideration, withdrawal of legal threats, or any other form of pressure. We will correct factual errors regardless of who points them out.

The full right-of-reply process is documented in our Editorial Policy.

What we don’t do

Changes to this methodology

Material changes to this methodology are noted in the changelog below. The methodology is reviewed annually and updated as the space evolves; significant changes in operator practices (new evasion patterns, new technical implementations) typically prompt updates to the criteria.
