Our ratings are not opinions. They are weighted calculations. This page shows the eight criteria, their individual weights, the formula that produces the final score, and the red flags that override everything else. If our score for Jackpot Jill surprises you, this page is where to come to check the maths.
We rate on a 1.0 to 10.0 scale, in 0.1 increments. Final review pages show the score divided by 2 (so on the main review it appears as "4.1/5") because five-star ratings are what readers and search engines expect; internally, everything is calculated out of 10.
Eight criteria feed the final score. Each is scored independently from 1.0 to 10.0 based on the Step output from How We Test. Each is then multiplied by its weight, and the eight weighted scores are summed. The weights add to 100%, so the weighted sum is itself on a 1–10 scale.
We picked the weights based on what actually affects a player's experience. Security is the heaviest because a casino that holds your money and cannot pay it out makes every other category irrelevant. Responsible Gambling is lowest-weighted but is still a mandatory minimum — a casino that scores under 5/10 on Responsible Gambling is excluded from our recommendation regardless of how well it does elsewhere.
| # | Criterion | Weight | What it measures |
|---|---|---|---|
| 1 | Security & Licensing | 20% | Licence validity, regulator strength, operator history, dispute resolution access, SSL and account security. |
| 2 | Bonuses & Promotions | 15% | Welcome bonus value, wagering realism, max-bet rules, game-weighting fairness, ongoing promo quality. |
| 3 | Games & Providers | 15% | Library size, provider diversity, live dealer quality, jackpot options, game performance and stability. |
| 4 | Payments | 12% | Rail coverage (card, bank, crypto, vouchers), deposit success rate, PayID support, fees. |
| 5 | Payout Speed | 13% | Measured withdrawal time from request to received funds, by rail. Weighted slightly higher than Payments because slow payouts hurt more than missing options. |
| 6 | Customer Support | 10% | Chat response time, agent competence on operational questions, channels available, hours. |
| 7 | Mobile Experience | 8% | Mobile browser parity with desktop, native app quality if offered, mobile cashier reliability. |
| 8 | Responsible Gambling | 7% | Deposit/loss/session limits, self-exclusion, reality checks, visibility of help resources, BetStop integration. |

Worked example using Jackpot Jill's April 2026 scores:
Sum: 8.19 / 10 = 4.1 / 5 (rounded to one decimal).
That is the number on the review. It is not rounded up to 4.2 because it looks friendlier. It is not rounded down to 4.0 because the reviewer felt critical. It is 4.1 because the maths produced 4.1.
Top anchor at 10/10: a UKGC or MGA licence in good standing, listed sister operators all without material unresolved complaints, full dispute-resolution pathway via an ADR body, 2FA available, HTTPS with HSTS preload. Mid anchor at 7/10: a Curaçao Gaming Control Board licence under post-LOK, recognisable operator group without major scandals, SSL without HSTS preload. Low anchor at 4/10: offshore licence of dubious regulator quality, operator group with unresolved complaint patterns, no account-security features. Below 4: unlicensed, or licence claimed but not verifiable.
Top anchor at 10/10: realistic wagering (≤35×), no hidden max-bet traps, transparent game weighting, meaningful ongoing rewards, no predatory "fraud" clauses. Mid anchor at 7/10: 40–45× wagering, standard max bet rule, reasonable ongoing offers. Low anchor at 4/10: 60×+ wagering, complex max-bet traps, short claim windows, ongoing offers that are essentially deposit-match clones.
Top anchor at 10/10: 3000+ titles, 30+ providers spanning NetEnt/Microgaming/Play'n GO/Evolution/Pragmatic Play/IGT, strong live-dealer coverage, progressive jackpot networks.

Top anchor at 10/10: full rail coverage including PayID, successful deposit on every method tested, no hidden fees. Mid anchor at 7/10: most rails work but PayID absent or card rail flaky, minor fees on some methods. Low anchor at 4/10: card rail broken for AU players, crypto-only effective coverage, hidden conversion fees.
Top anchor at 10/10: approval within 1 hour, funds received within 6 hours on at least one rail. Mid anchor at 7/10: approval within 24 hours, funds received within 48 hours. Low anchor at 4/10: 3-day+ approvals, manual reviews on every withdrawal, payment-method lock-in.
Top anchor at 10/10: 24/7 live chat with under-1-minute response, multi-channel (chat + email + phone), agents answer operational questions correctly. Mid anchor at 7/10: live chat with 1–3 minute response, chat + email only, agents adequate. Low anchor at 4/10: live chat slow (5+ minutes), email-only for non-chat hours, agents read from scripts without operational knowledge.
Top anchor at 10/10: feature parity across iPhone and Android, fast load, mobile-native cashier flows, optional native app. Mid anchor at 7/10: browser site works on both platforms with minor friction, cashier occasionally awkward on mobile. Low anchor at 4/10: registration or deposit breaks on mobile, critical pages unresponsive below tablet viewports.
Top anchor at 10/10: full toolset (deposit, loss, session, reality check, cool-off, self-exclusion), BetStop integration, reality-check pop-ups enabled by default, prominent link to help services on every page. Mid anchor at 7/10: main self-limit tools available, help link in footer, reality checks optional. Low anchor at 4/10: only self-exclusion available, no visible link to help services, opt-in-only limits buried in account settings. Below 5: we do not recommend, regardless of overall score.
| Final score | Five-star equivalent | Interpretation |
|---|---|---|
| 9.0–10.0 | 4.5–5.0 | Excellent. Top-tier operator on at least six of eight criteria, no material cons. Rare. |
| 8.0–8.9 | 4.0–4.4 | Very Good. Strong across the board, one or two weaknesses that do not affect core functionality. Jackpot Jill sits here at 8.2 / 4.1. |
| 7.0–7.9 | 3.5–3.9 | Good. Solid choice with recognised trade-offs. Recommended with caveats in the review. |
| 6.0–6.9 | 3.0–3.4 | Average. Works, but something meaningful is missing. Consider alternatives. |
| 5.0–5.9 | 2.5–2.9 | Below Average. Flawed in ways that matter. Not recommended for the typical player. |
| Below 5.0 | Below 2.5 | Not Recommended. Serious issues. Do not deposit. |
Some issues are severe enough to override the weighted calculation. When any of the following is confirmed, the final score is capped regardless of the criterion-level scores:
None of these auto-reductions currently apply to Jackpot Jill. If any ever did, the review would be updated within 48 hours of verification and the cap would show alongside the raw score.
Scores move when the underlying operator does. The 90-day re-test cycle documented on our Editorial Policy captures changes in wagering, bonus size, payment rails, licensing, and support quality. When one or more criterion scores shift materially, the final score is recalculated from the new inputs and the review is updated.
Historic example: in March 2026, Jackpot Jill raised the welcome bonus wagering from 40× to 50× and dropped PayID support. The Bonuses criterion went from 7.8 to 7.2, and Payments went from 7.6 to 7.0. Plug those new numbers into the formula and the final score drops from 8.34 to 8.19 — which rounds from 4.2/5 to 4.1/5 on the public page. That is the full audit trail behind the score movement.
