Bonus Code Types

You can use a bonus code at UK online casinos to access a range of different welcome bonuses. Just enter the code, make a deposit and enjoy your free spins or matched funds.

Deposit Match Bonuses

The deposit match is the simplest of casino welcome bonuses. You sign up for a new account, make a first deposit and receive bonus funds to the same value. You must clear your bonus cash several times over before being able to withdraw free cash into your account.

Casino Codes

For example, Spin & Win Casino offers a welcome bonus worth 100% up to £500. You need to enter the promo code when you open your online account. The minimum deposit is £10.

  • 1: Log in and open the cashier.
  • 2: Select the welcome offer from the drop-down list
  • 3: Make a minimum deposit worth £10. The max. is £500.
  • 4: Clear your bonus funds within 7 days by meeting the wagering conditions (40x deposit + bonus). For example, that means you’d have to gamble £40,000 (40 x £500+£500) before releasing your free £500.

Free Spins Casino Promo Codes

Some UK’s top online casinos, such as bet365 and Grosvenor offer free spins as part of their welcome bonus package. You may receive free spins straight from the off or after clearing a deposit bonus. Use free spins bonus code CG365 to claim 50 rounds at bet365 UK casino. By the way, these spins have no wagering requirements, keep all your winnings. View more low wager casinos here.

Casino Offer with Code

Always check the terms and conditions before you decide to use a promo code. Free spins bonuses usually have some sort of wagering requirement attached. You may have to play through your free spins winnings 5-10 times before you release them. There may also be a limit on the amount you can convert to real cash at the end.

No-Deposit Offers

Some British casinos, such as 888, let you access free bonus funds with no deposit required. To claim your no deposit bonus, you may need to enter a promo code when you sign up and receive £20, 50, 100 or more in free bet credits to use on casino games of your choice. You may have to clear your winnings by betting them 1-2 times over.

Welcome Bonus Code Terms & Conditions

Every online casino welcome bonus comes with some strict terms attached. You may invalidate your promotional codes if you don’t stick to the rules. Luckily, all top-rated casinos provide a list of terms and conditions for their promotions. Make sure you read them before you start playing.

Retention Bonuses and Promo Codes for Existing Customers

Casino sites also use promo codes for one-off bonuses used by existing players. These are usually offered if you have already cleared your welcome bonus.

Retention bonuses help to keep regular players happy but generally aren’t as large as welcome bonuses. In addition, ongoing casino bonuses tend to be targeted towards specific games such as slots and roulette.

You will need to opt in to the bonus via the cashier page. Make a minimum qualifying deposit and use the promo code provided by the online casino or one of these gambling apps. You’ll find this in your email inbox or on the casino website.

For example, The Vic Casino offers a 100% deposit match bonus worth £20 when you use the existing user promo code LIVE20. This loyalty bonus is eligible on live roulette only. View more casino promotions, including free spins and minimum deposit offers and a few cool slot bonuses.
