What You Should Look for in Casino Bonus

Now it’s time to explore some of the features that you should be looking out for when signing up with an online Casinos. As much as it’s important to land generous online Casino Bonus, you’ll also want these features to be in place, in order to make the most of them.

Casino Bonus for New Customers

new customer offers and Free Bets are one of the ways that Casinos attract new Players.

These deals come in different forms. In this section, we’re going to going to explore the various types of sign up offers that are available.

Bet & Get Deals

Of all the different sign up offers, this is the most common. As the name suggests, you have to place a bet, to get a bonus. So for example, the offer might be that when you bet £20, you get a £20 free bet.

With this sign-up bonus there are normally some stipulations in terms of your qualifying bet. These include eligible deposit methods such as a debit card, size of bet stake, minimum odds and eligible markets.

Once qualified, there are also rules regarding the bonus. It’s normally paid as a free bet bonus token rather than cash. There will be an upper limit in terms of the size of the bonus and there may also be stipulations regarding on what you can bet on and the minimum odds of that bet.

Money Back as a Free Bet

Another of the common sign up offers for are money-back deals. With this sign-up bonus you place a bet and if it loses, you get your stake back in the form of a free bet. It’s often known as a no-lose bet and it allows Players to be a little daring with their first bet, knowing that the worst that can happen is that they will get their stake back.

Again, there are rules that apply. There may be first deposit payment method exclusions, minimum odds, minimum bet stake and eligible markets, for the qualifying play. If that bet is a loser and you get your stake back, it will be as a free bet, up to a certain maximum amount. You can follow the tips of your choice and have the risk mitigated here.

Price Boosts

Our final type of Casino Bonus for new customers, are price boosts. These are quite rare now, but were once common. For a big event, a bet is available for new customers with the odds that are give a massive boost.

Generally it’s a favourite or selection that lots of people want to bet on. With the boosted odds being much larger than are available normally at online Casinos, Players will sign up for an account with the Casino Bonus deal.

Casino Bonus for Existing Customers

sign up offers for new users tend to grab the attention, but just as important are promotions available for existing Players.

Here are some of the best Casino Bonus that will make a difference for existing users.
