How BetterBonus Tests and Scores Online Casinos

Every casino listed on BetterBonus is tested with a real account. That means a real deposit from a personal card or e-wallet, a real bonus claim, wagering played through on actual games, and a withdrawal timed from request to confirmed funds. No casino in this list has been scored from a press kit, an operator submission, or a demo account. This page documents exactly what we test, how each finding contributes to a score, and what permanently removes a casino from consideration.
The Testing Process
Before any scoring begins, we complete six steps at every casino we evaluate. These are not optional and are not skipped for operators we have reviewed before.
Support is contacted with three specific test questions: one on active bonus terms, one on KYC requirements, and one on withdrawal processing. We record response time and whether the answer was accurate, not just whether a response was received.
Scoring Breakdown
Each casino receives a score out of 100 built from six weighted categories. The weightings reflect what materially affects a player's financial outcome and overall experience. Licence and bonus terms each carry the most weight because they determine whether your money is protected and whether an offer is actually clearable.
What Each Category Covers
We verify the licence number directly against the issuing regulator's public database: the UK Gambling Commission register, the Malta Gaming Authority register, the Gibraltar Regulatory Authority, or equivalent. We confirm the licence is active, covers the markets we are reviewing for, and names the brand in question. A Curaçao sub-licence and a UKGC licence carry meaningfully different consumer protections and are scored accordingly. We also identify the operator group behind the brand, note any documented regulatory sanctions in other markets, and confirm that responsible gambling tools including deposit limits, session limits, and self-exclusion are accessible directly from the account menu without requiring a support contact.
We read the full terms for every offer listed on BetterBonus. The wagering multiplier and the basis it applies to are two different numbers that most review sites treat as one. On a €100 deposit with a €100 bonus, 35x applied to bonus only means €3,500 in required wagers before withdrawal. The same 35x applied to deposit plus bonus means €7,000. We document which basis applies and translate it into plain figures. We also check game contribution rates (slots typically 100%, table games often 10% or lower, live casino often excluded or reduced), maximum bet per spin during wagering (commonly €5, exceeding it voids the bonus), time limits to complete playthrough, and whether a bonus is cashable or non-cashable. Anything above 40x is flagged as high-wagering. Casinos with a wagering requirement above 60x are removed from featured positions regardless of other scores.
We create a real account, complete identity verification, deposit real funds, and request a withdrawal to record actual processing times. Pending time and processing time are recorded separately because the distinction matters: a casino can have fast processing after releasing funds and still be a slow payer if it holds withdrawals for 24 hours before releasing them. We document withdrawal speeds for common methods, deposit minimums, withdrawal caps, and whether the payment methods that activate a bonus are stated in the key terms or buried in the full document. Local payment method availability and regional restrictions are documented per market.
We check which software providers supply the game library and whether they are established, certified studios: Pragmatic Play, NetEnt, Evolution, Nolimit City, Play'n GO, Push Gaming, or equivalent. RTP figures should be accessible in-game or via a linked game information sheet. We flag casinos that obscure stated return percentages or list figures not supported by the provider's published data. We note variety across game types: slots, table games, live casino, and jackpot titles. A catalogue limited to slots from one or two providers scores lower regardless of volume.
We assess registration flow, mobile platform quality, and the accessibility of responsible gambling tools. A casino that requires a support chat to access self-exclusion or deposit limits scores lower than one where those controls are visible in the account menu. We test on both desktop and mobile (iOS and Android via browser), checking game loading speed on 4G, cashier flow, and whether features available on desktop are equally accessible on mobile. Responsible gambling controls that are buried, non-functional, or require a support request to activate are treated as a significant negative regardless of what the terms page states.
We contact support with three specific questions: one on the active welcome offer terms (specifically whether wagering applies to bonus only or bonus plus deposit), one on KYC requirements, and one on withdrawal processing times for a named method. We record response time and whether the answer was accurate. A casino where the support agent gives a factually wrong answer on bonus terms scores lower than one where the answer is correct and clear. Scripted deflections that redirect to the terms document without answering the question count as a wrong answer.
Automatic Disqualifiers
The following findings remove a casino from consideration entirely, regardless of its score in other categories. These are firm exclusions with no exceptions.
- No active, verifiable licence for the target market at time of review
- Documented non-payment of legitimate winnings not subsequently resolved with evidence
- Bonus terms containing clauses that allow winnings to be voided without defined criteria, for example “the casino reserves the right to cancel any bonus or winnings at its sole discretion” with no qualifying conditions listed
- No functional responsible gambling tools: deposit limits, session limits, or self-exclusion accessible without contacting support
- Active sanctions or licence suspension issued by a recognised regulatory authority
A casino with strong scores in every other category remains excluded if any disqualifier applies. These criteria do not bend for commercial relationships.
How Ratings Stay Current
Bonus terms change. Licences are revoked. Operators are acquired. A rating that was accurate six months ago may not be accurate today. We run scheduled rechecks on every listed casino based on the following schedule:
When ownership, wagering requirements, withdrawal limits, or licence status changes materially, the listing is re-evaluated from scratch and the last-reviewed date is updated on the relevant page. Changes that affect player value are annotated directly on the casino's review page.
If you find an error, a withdrawal time that does not reflect your experience, outdated bonus terms, or an incorrect licence number, contact [email protected] with the page URL and what you believe is wrong. We check against the primary source and correct within 48 hours when errors are confirmed.
Commercial Relationships and Editorial Independence
BetterBonus earns affiliate commissions when readers register through our links. This is disclosed on every page where affiliate links appear and explained in full in our Editorial Policy.
A commercial relationship does not change a score. Some of the highest-commission operators on this site have the weakest ratings. Placement within some featured lists can be influenced by commercial arrangements, and when that is the case it is labelled. Within standard editorial rankings, position reflects scoring criteria, not payment.
If a casino asks us to change a rating, the answer is no. If a rating changes because the casino genuinely improved or declined, we update it and note what changed and when.
