If you've never played at an online casino, the first visit can feel like walking into a members' club without knowing the house rules. Most of the rules are there to protect you. This page walks through them in the order you'll meet them.
Start with the licence
In Great Britain, any business offering casino games to people here needs a licence from the UK Gambling Commission. That's the single most useful fact to check. A licensed operator has to verify your age, keep customer money handling to set standards, offer safer-gambling tools and handle complaints through an approved dispute service.
You don't have to take anyone's word for it, ours included. The Commission's public register lists every licensee. Search the account number (you'll find it in a casino's footer, and in each of our reviews) and check the trading names match the site you're on.
All five casinos we compare belong to two operators: Skill On Net Ltd, account 39326, and ProgressPlay Limited, account 39335.
Signing up: expect checks before you play
UK casinos must confirm you're 18 or over before you can deposit or play, even on free-to-play demo games. Usually that's done automatically from your name, date of birth and address. Sometimes you'll be asked for a photo of your ID or a recent bill.
It can feel like a hurdle. It also means nobody can open an account in your name without the operator noticing, and it's much better done at the start than when you ask to withdraw.
A few practical points
- Use your real details. Mismatches are the most common reason withdrawals get held up.
- One account per person per casino. Duplicate accounts are usually closed and bonuses removed.
- Some sites confirm your mobile number by text; PlayKasino is one of them.
Paying in and taking money out
Credit cards can't be used for gambling in Great Britain; that ban has been in place since April 2020. Debit cards and a range of other methods are common, but they vary by casino, so we don't list methods we haven't seen in the operators' own information. The cashier page shows what's open to your account.
Two details catch people out. First, some bonuses exclude certain deposit methods: at The Online Casino and Vegas Mobile, Skrill and Neteller deposits don't qualify for the welcome offer. Second, withdrawals normally go back to the method you paid in with, where that's possible.
How quickly a withdrawal lands depends on the operator's checks and on the method. We'd rather say "check the cashier" than print a number we can't stand behind.
How bonuses actually work
A welcome bonus usually comes in two parts: a deposit match (you pay £20, they add £20 of bonus money) and free spins on a named slot. Neither is cash yet. Before you can withdraw it, you'll need to meet the wagering requirement, which is a multiple of the bonus.
Since 19 January 2026, the Gambling Commission caps that multiple at 10x. So every offer on our list asks for 10x. The differences sit elsewhere:
- Time limits. Mostly 30 days, but some spin winnings expire after 7.
- Max conversion. A ceiling on what the bonus can turn into; £50 at two of our five brands.
- Game contribution. Some bonuses count slots only.
- Max bet. Skill On Net brands cap bets at 10% of your bonus and spin winnings, or £5, whichever is lower.
- Order of play. Some sites use your cash first, others the bonus first.
Each of our reviews includes a worked example in pounds, using that casino's real numbers. It's the quickest way to see what you're signing up for. And remember that you can simply decline a bonus.
The controls you're entitled to
Every UK-licensed casino has to give you tools to manage your play. Set them early, when you're calm and nothing is at stake.
| Tool | What it does |
|---|---|
| Deposit limit | Caps what you can pay in per day, week or month. Lowering it is immediate; raising it has a cooling-off delay. |
| Reality check | A reminder that pops up after a set time, showing how long you've been playing. |
| Time-out | A short break, from a day up to a few weeks, during which you can't log in to play. |
| Self-exclusion | Closes your account for six months or more. GAMSTOP does it for every licensed site at once. |
There's more on all of this, plus warning signs worth knowing, on our play safe page.
A short glossary
- Wagering requirement
- The amount you must bet before bonus funds can be withdrawn. 10x a £30 bonus is £300 of bets.
- Spin value
- The stake each free spin is played at. 100 spins at £0.10 is £10 of play.
- Max conversion
- The most a bonus can turn into as withdrawable cash.
- RTP
- Return to player: the share of all stakes a game is designed to pay back over a very long run. It says nothing about a single session.
- Volatility
- How a game spreads its returns: lots of small wins, or fewer bigger ones with long gaps.
- Significant terms
- The key conditions of an offer, which UK rules say should be shown alongside it. We show them in full next to every button.
