Online UK-based slots casinos want to attract players who place significant deposits. The biggest the deposit, the larger the winnings.

Because of this, many casinos now offer welcome bonuses, a kind of reward which encourages players to sign up and start betting.

What Is A Casino Slot Welcome Bonus?

Casino Slots UKA welcome deposit bonus usually comes in the form of a percentage addition to a starter deposit. Suppose, for instance, you deposit £50 into your account when you first join a new casino. If the casino offers a welcome bonus, then it will add money to your initial deposit, increasing the amount of money that you have to play with. If the welcome bonus is 20 percent, then you will end up with £50 in your account, plus an additional £10 (which is 20 percent of £50), giving you a total of £60 which can be used to play casino slots or other games

Different casinos offer different percentage bonuses. You could get a bonus anywhere from 100% to 300%, depending on the provider. Casinos may also offer fixed welcome bonuses. For instance, when you join the casino, it may automatically credit your account a £5 free no deposit bonus or even £10 free no deposit bonus that you’re free to use on their casino slots, just as if you’d deposited it yourself.

Non-Cashable Casino Slot Bonuses

Some slots casinos also offer what are called “non-cashable” bonuses. As the name implies, you cannot exchange these bonuses for cash but you a free to play the casino slots and games with the bonus. Even if you meet wagering requirements and withdraw the winnings from the money you deposit yourself, you cannot take out a non-cashable bonus: that goes back to the casino.

Other Types Of Casino Slot Bonuses And Promotions

Cash isn’t the only welcome bonus that casinos offer. Many also provide new players with in-game perks designed to increase their chances of winning. Casinos in the UK, for instance, may provide players with 50 free spins in slot games as part of their welcome deals. Customers can either use these promotions or not as they please.

Casinos also offer something called a “free play bonus.” A free play bonus is where the casino offers you credit of some kind but insists that you use it within a given time limit. The time limit, of course, depends on the casino’s policies.

How Long Does It Take To Open An Account And Play Casino Slots?

play casino slotsCasino slots sites differs in the way they welcomes new customers. Some online slots casinos insist that customers meet specific requirements or contact customer service before being able to enjoy a welcome bonus.

Others ask customers to enter a code, rather like you would a coupon, to start experiencing benefits. Your experience will depend very much on the provider and the rules set out in their terms and conditions. If you haven’t been a member of the casino before, then it’s worth checking what the company says in this document and about how players can use welcome bonus cash. Some only allow the bonus to be used on certain casino slots or & remember, some casinos don’t allow you to withdraw winnings made on bonus cash, so you could end up disappointed. All the casino slots we feature are compatible on mobile phones and devices, including tablets and iPads, allowing you to use them wherever you happen to be.
