Every figure on the leaderboard was read from the operators' own offer terms and fed through the formula in our lab note. Where the terms left something out, we say so instead of filling the gap.

02 · Method

How the score is built

Each offer gets five sub-scores out of 10. They're multiplied by fixed weights and added up. That's the whole thing. No hidden adjustments, no "editor's feel" bonus.

score = 0.20·B + 0.30·W + 0.15·S + 0.15·D + 0.20·L

Wagering carries the most weight because it decides how much of a bonus you can realistically keep. Licence is weighted as heavily as bonus size on purpose: every casino here holds a UKGC licence, so the metric mostly measures how much the operator tells you about itself.

Full methodology Formula, worked through

What we checked

  • The offer headline and significant terms as shown on each UK landing page on 30 September 2026
  • Wagering multiple, deadlines, stake per spin, conversion caps and minimum deposit, parsed from those terms
  • Each operator's UKGC account number, linked to its public-register page

What we couldn't

  • Payment methods and withdrawal times: not in the material we captured, so check the cashier
  • Game counts beyond what operators advertise
  • Stake per spin at Vegas Mobile Casino and The Online Casino: not in the terms, so 10p is assumed and flagged
  • The match percentage behind the Vegas Mobile Casino package: not published in the terms we hold
  • Anything that happens after sign-up: support quality, verification speed, account reviews

04 · Review notes

What each scorecard doesn't show on its own

Luna Casino 6.3

The highest lab score of the five. A £50 match plus 50 spins at a stated 10p, 10x on bonus and spin winnings together, and a full 30 days to do it. The terms also say bonuses don't stop you withdrawing your deposit balance, which is less common than it should be.

Luna Casino: full review

Swift Casino 6.2

Half the cash of Luna, twice the spins. £25 match and 100 spins at 10p gives a balanced split between bonus and spin value, and the same 30-day 10x structure as its Skill On Net siblings. A smaller catalogue claim (1,200+ games) than Luna.

Swift Casino: full review

PlayKasino 6.1

Spins only: 200 on Book of Dead at 10p each, which is £20 of face value for a £20 deposit. No cash match at all, so it scores zero on bonus size and top marks on spin value. Wagering applies to spin winnings only, which keeps the turnover small.

PlayKasino: full review

Vegas Mobile Casino 6.0

The biggest headline number on the page and the biggest gap between headline and withdrawable value. The package runs to £1,000 plus 100 spins across deposits, but bonus conversion is capped at £50 and spin winnings at £20. Read it as a small bonus with a lot of playtime attached.

Vegas Mobile Casino: full review

The Online Casino 5.4

A plain 100% match to £50 with 20 spins on Big Bass Bonanza. The bonus itself is capped at £50 conversion, which happens to equal the maximum bonus, so the cap bites less here than it does at its sister site. The 7-day spin window and the Skrill/Neteller exclusion are the two lines to read twice.

05 · Questions

Questions we get about the scores

Q01How is the leaderboard ordered?
By lab score, highest first. The score is calculated from the published terms and doesn't move with commission. The list still carries an Ad label because we earn a commission from every casino on it.
Q02Do the scores tell me which casino I'll do best at?
No. They compare the structure of welcome offers: how much of the headline can become withdrawable, how much turnover is required, how much the entry costs. Results at any casino depend on chance, and over time the house has the edge.
Q03How often are the offers checked?
The terms on this page were last checked on the date shown at the top. Casinos change offers without notice, so the operator's own terms page is always the final word.
Q04What does 10x wagering mean in pounds?
You have to place bets worth ten times the bonus (and, depending on the offer, ten times any free spin winnings) before the bonus money can be withdrawn. A £50 bonus means £500 of bets. Our lab note works this through for each casino.
Q05Are all five casinos licensed in Great Britain?
Yes. Each operator's UK Gambling Commission account number is listed on its review with a link to the public register, so you can check the status yourself.
Q06Can I use these offers if I've self-excluded with GAMSTOP?
No, and you shouldn't try. All five brands take part in GAMSTOP. If you've registered, the scheme is working as intended.
Q07Why don't you list more casinos?
We only publish a score where we can build it entirely from terms we've captured and can quote verbatim. Five is the number we can do that for properly right now.

06 · Before you play

Set the limit before the bonus sets it for you

A welcome offer is designed to keep you playing through the wagering. That's worth knowing going in. Decide what you can afford to lose, set a deposit limit in the account before your first deposit, and treat any bonus as entertainment money, not a way to make money.

If gambling has stopped being fun, or you're spending more than you planned, free and confidential help is available around the clock.
