How this site works, in three steps

1 We read the small print

Each offer shows its significant terms copied word for word from the casino. We read every line, including the dull ones about caps and deadlines.
2 We translate it

Next to the legal wording you'll find what it means for you: how much play a bonus asks for, what you can take out, and what happens if you change your mind.
3 You decide, or don’t

No countdowns, no pressure. If none of these suit you, that's a perfectly good result. Closing the tab is always an option.

Quick sum

How much play does a bonus ask for?

All five offers use a 10x playthrough. That means the bonus (and at some casinos, spin winnings too) has to be bet ten times over before it can turn into cash you can withdraw.

It isn't money you need to deposit. It's the running total of every stake you place, including stakes made with winnings you've recycled. Try a number and see.

Which offer suits you?

Four quick pointers, taken straight from the offer terms. None of this is a recommendation to play.

Lowest deposit

£10 gets you started at Swift Casino, The Online Casino, Vegas Mobile Casino and Luna Casino. PlayKasino asks for £20.

Most free spins

PlayKasino: 200 spins on Book of Dead at £0.10 each, so £20 of spins at face value.

Biggest match

The Online Casino and Luna Casino both match 100% up to £50. Vegas Mobile Casino has the largest headline package (up to £1,000), but its terms cap bonus cash-out at £50.

Codes

Swift Casino lists the code SWIFT; Luna Casino lists the code LUNA. The other 3 don't use one.

How we score, in one paragraph

Each brand gets a mark out of ten on four things, weighted by how much they matter to someone claiming a welcome offer. Scores are our editorial opinion, not user ratings, and a commission never buys a higher one.

How clear the offer is 30%
How fair the playthrough is 30%
Who is behind it 20%
The site and its games 20%

Staying in control

Welcome offers are designed to get you playing. That's fine, as long as you're the one setting the pace. A few habits that genuinely help:

Set a deposit limit while you sign up. Every UK licensed casino has to offer one. Lowering it applies promptly; raising it means a cooling-off wait of at least 24 hours.
Decide what an evening's entertainment is worth to you, and treat that money as spent.
Use reality checks: the pop-up reminder of how long you've been playing is there for a reason.
Take a time-out if you notice you're chasing a loss. Chasing is the moment to stop, not to top up.
If you want a proper break, GAMSTOP blocks you from every UK licensed gambling site at once, for 6 months, a year or 5 years.

Questions people ask us

Is Plain Bonus Guide a casino?

No. We don't take bets or hold money. We compare welcome offers from casinos licensed in Great Britain and link to them. If you sign up through one of our links we may earn a commission.

Are all of these casinos licensed?

Yes. Each review names the licence holder and links to its entry on the UK Gambling Commission's public register, so you can check it yourself in under a minute.

What does "10x wagering" mean?

You need to place bets worth ten times the bonus (or the spin winnings) before it can be withdrawn. On a £20 bonus that's £200 of bets. The calculator does the sums for you.

Do I have to take a bonus?

No. Some terms let you ask for a bonus to be cancelled. Playing without one means no playthrough and no caps, which some people prefer.

Why do the offer lists say "Ad"?

Because the casinos pay us when someone signs up through our links. The label is there so that's clear before you click. Our disclosure page explains the rest.

I've signed up to GAMSTOP. Can I use these sites?

No, and that's by design. All five brands take part in GAMSTOP, so your self-exclusion blocks you until it ends. If you're finding the exclusion hard, GamCare can help on 0808 8020 133.

Will a welcome bonus help me win?

Honestly, it's unlikely to change much. Casino games have a built-in house edge, so over time the casino comes out ahead. A bonus gives you more play for your deposit. Think of it that way and you won't be disappointed.
