The six sub-scores
Our editorial score is a weighted composite of six dimensions, each scored 0–10. The weights are deliberately even-ish — no single dimension can drive the entire ranking.
| Dimension | Weight | What we measure |
|---|---|---|
| Bonus Value | 18% | Welcome offer face value at minimum deposit, divided by effective wagering cost. Adjusted for max-win caps and time-to-clear. |
| App & Mobile Experience | 18% | Cold-start speed (timed), iOS & Android store ratings (rolling 12-month), navigation complexity score, accessibility audit. |
| Game Variety | 16% | Bingo format coverage (90, 75, 80, 30, 50, Slingo, Pattern), room schedule breadth, RTP transparency. |
| Payments & Withdrawal Speed | 18% | Median withdrawal time across 30+ test withdrawals per operator. Variance also scored, alongside deposit and withdrawal method breadth. |
| Support & Community | 15% | Hosted chat hours, host responsiveness, chat-room sentiment scoring (manual sample), tournament participation, plus contact-channel coverage and response times. |
| Trust, Licence & Player Protection | 15% | UKGC licence status and enforcement history, group ownership and financial standing, deposit-limit accessibility, reality-check defaults, GAMSTOP integration and self-exclusion friction. |
Every overall score on this site is that table applied to the six published sub-scores, rounded to one decimal place — nothing else goes into it. You can reproduce any rating we publish from the sub-scores on the operator's own review page. If your arithmetic disagrees with our number, our number is wrong, and we want to hear about it.
The testing protocol
- Account opening. Register fresh test account using approved test identity (UKGC-compliant). Time the verification process. Log all friction.
- Deposit testing. Test every supported deposit method at minimum, mid, and maximum values. Log instant-credit or delay.
- Welcome bonus. Claim. Track wagering progress in a spreadsheet. Time-to-clear logged.
- Gameplay. Minimum 200 ticket purchases across all available bingo formats over the testing period. We don't optimise to win — we play standard sessions.
- Withdrawals. Minimum 30 withdrawals across the testing period, varying amount and payment method. Each timed from request to landed-in-bank.
- Chat-room sampling. Minimum 25 hours of chat-room observation across peak and off-peak hours. Host quality manually scored.
- Customer support. Live chat, email, and phone (if available) contact. Response time and quality both scored.
- Responsible-gambling stress test. Set deposit limits at every level. Trigger reality-check. Initiate (and rescind) self-exclusion. Friction logged at each step.
- Mobile app audit. Cold-start timed on iPhone 12 and Pixel 7. Accessibility audit (VoiceOver, TalkBack). Push notifications tested.
What we don't do
- We don't accept payment for placement. Operators have offered. We have declined.
- We don't share drafts with operators. They see the published review at the same time as readers.
- We don't adjust scores for affiliate value. The two are separate processes, handled by different teams, with no cross-referencing.
- We don't review unlicensed operators favourably. Operators without UKGC, MGA or Gibraltar licences are listed only with explicit risk warnings, never in the editorial top 50.
- We don't recommend offshore bonus chasing. Offshore 30× wagering offers will always score lower than 4× UK offers, even when the headline value is higher.
Re-testing schedule
Top-25 operators are re-tested every six months. Operators ranked 26–50 every nine months. The long tail every 12 months. Withdrawal-speed numbers and welcome-offer terms are checked weekly across the top 25 and updated on the listing pages within 48 hours of any change.
What changes between methodology versions
We publish a methodology version number (currently v3.3) and release notes. Major version changes (v2 → v3) happen when we add or remove a sub-score; we re-score the entire top 25 within four weeks. Minor versions (v3.1 → v3.2) update weights or measurement protocols; we re-score within eight weeks.
Past methodology versions are kept publicly accessible. If a score has changed because the operator improved, you can see it. If a score has changed because we changed how we measure, you can see that too.
v3.3 — 3 August 2026
A reader-facing correction, and the least comfortable kind: our own numbers did not add up.
This page and the FAQ on our best UK bingo sites ranking had drifted into publishing two different sets of weights and two different minimum testing periods. Worse, each operator's overall score was being maintained by hand alongside the six sub-scores it is supposed to be calculated from, so it could drift away from them — and it had. Two operators were materially misstated: Buzz Bingo was published at 8.7 against a composite of 8.15, and Sun Bingo at 8.4 against 7.26. Most of the rest were fractionally generous.
Three things changed. The weights above are now the single published set, and this table is generated from the same definition the arithmetic uses, so the two cannot diverge again. The minimum testing period is eight weeks everywhere. And overall scores are no longer written by hand at all — every rating on the site is now computed from its sub-scores at build time, which is why several have moved without any operator's product changing.
Scores that moved: Buzz Bingo 8.7 → 8.1, Sun Bingo 8.4 → 7.3, Mecca Bingo 8.9 → 8.7, Heart Bingo 8.2 → 8.0, Gala Bingo 8.6 → 8.5, Jackpotjoy 8.6 → 8.5, William Hill 7.8 → 7.7. Tombola (9.4), Paddy Power (8.8) and Foxy Bingo (8.3) were already correct. No sub-score was altered, because no operator was re-tested — this release corrects arithmetic, not judgement.
"The score is only as honest as the methodology. The methodology is only as honest as it is public."
Disagreement
Operators occasionally dispute our scores. We will publish their disagreement alongside ours, in full, with no edits. We will not change the score in response to commercial pressure. We have lost three affiliate agreements over published reviews. We will lose more.
Audit
An external editor unrelated to the publication reviews our scoring annually. The 2025 audit report is here. The 2026 audit is in progress.
