What is a Casino Welcome Bonus?

Most online casinos offer some sort of sign-up bonus. These are special deals reserved for new players. All you need to do is open an account and fill in your personal details. You may also have to enter a special promo code when registering. Once you’ve opened your account, open the cashier and make a first deposit. You’ll receive bonus funds to play with. You can unlock free cash as long as you meet the wagering requirements stated in the terms and conditions.

  • Casino New Customer Welcome Bonus
    A deposit match is the most common form of welcome bonus among the best UK online casino sites/apps. Just make a first deposit and the casino will match it 100% with bonus funds. You can withdraw your matched cash as long as you play enough eligible slots and games. You’ll also have to meet the required time limit (e.g. 7 days from starting the bonus).
  • Online Casino Free Spins
    Many casino bonuses in the UK also include free spins on a big slot. Free spins new customer casino bonus carry a fixed price and you’ll only be able to win a maximum amount. Some free spins deals work on a time limit. Instead of a number of spins, you may get 30 seconds to 1 minute to try and win as much as you can.

How to Read Casino Wagering Terms and Bonus Conditions

Virtually all online casino welcome bonuses will come with some playing terms attached. It’s important you read the terms and conditions before you open your account and opt in to the promotion.

Wagering Multipliers: Bonuses normally come with wagering requirements. This is the amount you will have to gamble in order to release your winnings.

Here’s an example: imagine you claim a 100% welcome bonus deposit match and load up your account with £100. The casino matches it with £100 in bonus funds and lists the wagering requirement as 30x. Now, in order to release your bonus funds, you’ll have to gamble £3,000 (30 x £100).

Some online casino wagering requirements apply to the deposit + bonus total. In our example, if you deposited £100 and received £100 in bonus funds, you’d have to wager £6,000 (30 x £200).

Game Contribution Rates: Not every game contributes the same amount towards your welcome bonus. Casinos vary in the amount they allow you to contribute. Again, it’s worth checking the terms before you begin.

Example game/slots contribution rates:

All online slots: 100%
Roulette, blackjack: 20%
All other table games: 10%
Video poker: 10%
Keno: 5%
All other games: 0%

Expiry Date: A deposit match will usually carry a strict expiry date. For instance, you may have to claim your bonus within 30 days of joining a casino. Once you opt in to the bonus, you’ll have 7-14 days to complete the wagering requirements.

Wagering Requirement: All deposit bonuses feature a wagering requirement. This is the amount you must wager in total relative to your deposit. For example, imagine a casino offers a 100% match bonus up to £500 and the wagering requirement is 50x. That means if you were to deposit £500, you would have to bet £25,000 (£500 x 50) in order to withdraw your £500.

Restricted Casino Games: As well as contribution rates, you need to look at game eligibility. Some games – normally high-paying slots –will be exempt from your bonus terms. You’ll usually find a full list of prohibited slots on the bonus terms page.

Online Casino Reload Promos & Rewards

A welcome bonus isn’t the only deposit match offer you’ll find at an online casino. Many gambling sites offer reload bonuses which you can use once you’ve successfully cleared your welcome bonus. A reload bonus will normally match 25-50% of your second or third deposit. So, for example, if you reloaded £200, the casino would match it to a value of around £50-£100. Again, watch out for wagering terms so you can clear the bonus funds without any disappointment.

Can I open multiple accounts to claim welcome bonuses in the UK?

You can open accounts at different casinos, but you’ll only be able to open one account at each site. You must be aged 18 or over to sign up to a UK casino.

How much money can I win with a welcome bonus?

Most online casinos offer a 100% deposit match up to £500. You must make a qualifying deposit by debit card or bank transfer to take advantage.

What is a welcome bonus free spins promotion?

Free spins are offered on selected slots. Spins carry maximum stakes and you can only win a certain amount. Unlock your winnings by meeting the wagering terms.

Do I have to make a deposit to claim a welcome bonus?

Not always. Some online casinos offer no-deposit bonus funds and free spins for players who want to test the waters without making a deposit first.
