How to Claim a Casino Bonus

Claiming a welcome bonus is straightforward. Follow these four steps to get your offer.

Choose a Casino

Browse the comparison above and select the offer that best fits your budget and preferred game type. Consider the bonus percentage, free spins, and wagering requirements.

Register Your Account

Click “Get Bonus” to go directly to the casino. Complete the registration form with your details. All operators listed require ID verification under UK law.

Make Your Deposit

Fund your account using your preferred payment method. Ensure your deposit meets the minimum amount required by the offer (usually £10–£20) to qualify for the bonus.

Claim & Play

Your bonus is typically credited automatically. Check your casino account or promotions page to confirm. Read the wagering terms before playing to know your withdrawal conditions.

Bonus terms vary by operator. Always read the full terms on the casino’s website before depositing. Wagering requirements, eligible games, and expiry dates vary — always check the operator’s full terms.

Understanding Casino Bonuses

What is a Welcome Bonus?

A welcome bonus is a promotional offer given to new players when they register and make their first deposit at an online casino. The most common form is a matched deposit bonus, where the casino matches a percentage of your deposit up to a maximum amount.

For example, a 100% bonus up to £100 means if you deposit £100, you’ll receive an additional £100 in bonus funds, giving you £200 to play with. A 200% bonus up to £200 means a £100 deposit gives you £300 total.

What are Wagering Requirements?

Wagering requirements (also called playthrough requirements) specify how many times you must bet your bonus amount before you can withdraw any winnings. A 30x wagering requirement on a £100 bonus means you must wager £3,000 before withdrawing.

No-wagering bonuses have zero wagering requirements — meaning your winnings are yours immediately. Always check the wagering requirements before claiming a bonus.

Free Spins Explained

Free spins allow you to spin a specified slot game without using your own funds. They are typically awarded on a named game and may have a fixed stake per spin. Winnings from free spins may be subject to wagering requirements or, in the case of no-wager bonuses, credited as real cash immediately.

Deposit Match vs. Free Spins

Deposit match bonuses give you more funds to play a wide range of games. Free spins are limited to specific slots but can deliver real value if the game’s RTP is high. Some operators offer both together, making their packages particularly attractive.

Responsible Gambling

Gambling should always be enjoyable and within your means. If it stops feeling that way, help is available — free, confidential, and without judgement.

Rules for Safer Play

  • Set a deposit limit before you start and stick to it, no matter the outcome.
  • Never borrow money or use credit to fund gambling.
  • Take regular breaks. Set a time limit on each session.
  • Do not gamble when you are upset, tired, or under the influence of alcohol.
  • Treat losses as the cost of entertainment, not money owed back to you.
  • If gambling stops being fun, it’s time to stop.

Tools Available to You

All UKGC-licensed casinos are required to offer responsible gambling tools including deposit limits, loss limits, session time limits, cooling-off periods, and self-exclusion. These tools are available in your account settings on every casino listed here.
