What Are Slots Bonuses?
Slots bonuses are incentives offered by slot sites to attract new customers to sign up and play their games for real money. All sites also offer bonuses to existing customers to encourage them to return and play more.
Typically, a slots bonus will come in the form of ‘bonus funds’ or ‘free spins’ that can be used to play your favourite games. Thanks to the UK’s competitive casino market there are always generous deals available. But bonuses rarely come without restrictions and it’s important to understand how they work, including typical terms and conditions, before you pick one.
Pros And Cons of Slots Bonuses – Should You Opt-Out?
In principle, slots bonuses sounds like something everyone would want. But restrictive terms and conditions can put some players off. Here are the pros and cons to think about before accepting a bonus.
Pros
- Get more play time from your deposit
- Test new slot sites with your bonus or spins
- Use free spins to try new games that you might not ordinarily play
Cons
- Terms and conditions can be difficult to understand
- Restrictions on use of bonuses can mean you can’t use funds on your favourite games
- Restrictions on withdrawals can negate the benefits of winning with bonus funds
- Some payment services are excluded from bonuses
Opting-Out Of Slots Welcome Bonuses
If the welcome package at a new site you are thinking of playing at feels too restrictive or the eligible games aren’t ones you are interested in, you can always opt out. Some slot sites require you to ‘opt in’ to receive a bonus anyway. In that case, just don’t tick the box to receive the bonus. Alternatively, you can contact the support team to ensure you don’t receive the bonus, or an existing bonus is removed. There is never an obligation to accept a bonus.
Types of Slots Bonus
There are several different types of slots bonuses. To help you decide which to choose, here is a brief description of each one. You’ll notice that many slot sites give away a mix of free spins AND deposit match bonus in their sign up deal.
Deposit Match Bonus
This is the most common type of slots bonus. The house matches a percentage of your deposit in bonus money. For example, a 100% match means a £50 deposit receives £50 in bonus money. For example, Barz Casino are currently matching first deposits up to £300.
Free Spins
Many slot bonuses come in the form of free spins. These are free plays on popular slot games. The stake size will be pre-determined, typically 10p. And in most cases winnings will be paid in bonus money, with a limit on how much can be won. The bonus money will then have a wagering requirement applied to it. For example, at Play OJO you can currently get 80 free spins on Big Bass Bonanza with your first deposit of £10 or more.
No Deposit Bonus
A no deposit bonus is credited on sign-up before the player has even made a deposit. These kind of offers are rarer than they used to be but from time to time they become available at some sites. They will normally be in the form of free spins.
No Wagering Bonuses
A no wagering bonus is one that has no wagering requirements attached to it. That means the bonus money is ‘cash’ that can be withdrawn without any restrictions. Most no wagering bonuses are free spins deals but sometimes other bonuses, like cashback, are ‘no wagering’ too. For example, at Kwiff Casino you can currently get 200 ‘wager free’ spins on Book of Dead by Play n Go when you deposit £20.
VIP or Loyalty Bonus
Loyalty bonuses are reserved for customers who play regularly on a slot site. They are normally based on accrual of points in a loyalty program. Points are normally awarded for wagering with real money. Not all slot sites have a loyalty program. You can check our reviews to find out which ones do. A good example is Casumo which awards points for your activity on the site, leading to bonuses and free spins when you hit each new level.
Cashback Bonus
A cashback bonus is paid as a percentage of money spent at a slot site. For example, a 10% cashback deal means you get 10% back on money spent over the period of the offer. If you deposit £100 and withdrew nothing, you would get £10 back in this case. One of the best cashback set ups right now is All British Casino which gives every player 10% cashback weekly for life.
Understanding Slots Bonus Terms and Conditions
Those are the most common types of slots bonus. There are easy to understand but you must also pay attention to the restrictions placed on your bonus. These are specified in the terms and conditions that must be published alongside the offer at your chosen slot site according to UK regulations.
Restrictions are there to limit the liability from bonuses for the operator. They are providing free bets and it wouldn’t be good for business if customers could simply cash out the money and walk away with it.
These are the important terms to look out for:
Minimum deposit – how much you need to deposit to receive the bonus. Usually £10, but sometimes £20 or higher.
Maximum bonus – the cap on how much bonus money or free spins you will receive.
Wagering requirements – bonus money, and any winnings generated from it, cannot be withdrawn until an amount equivalent to a multiple of its value has been wagered. A typical wagering requirement would be 30x. In that case, for a bonus of £10 with a 30x wagering requirement, £300 must be wagered before that bonus can be withdrawn.
Game Contributions or Weightings – often, not all games will contribute equally towards wagering requirements. Games with higher RTP (high RTP slots, blackjack, roulette, live dealer tables, video poker) will count less, sometimes just 10%.
The good news is most slots count 100%. However, it’s always worth checking the terms and conditions to be sure that your bets are working as you expect towards the total wagering requirements.
Win Limits – some slot sites will cap the amount that can be won with a bonus Typically, a cap would be £100 but it may as high as £500. Some casinos operate a ‘no max cashout’ policy.
Expiry Date – the time within which you must claim or use a bonus. For example, some sign up offers are only valid for 30 days from registration. And some free spins will expire after just 24 hours.
Maximum Bet – some sites will set a maximum stake level for betting with bonus money. This is typically £5 but may be less in some cases.
Excluded Payment Methods – some payment methods may be excluded from slots bonuses. In particular, deposits from eWallets like Neteller and Skrill are not eligible for offers.
NOTE: Every casino handles bonus terms and conditions in their own way. Don’t assume that your next bonus will be the same as your last. Always read the terms and conditions to be sure you are getting what you want.
To Conclude: 5 Things To Think About When Choosing A Slots Bonus
Now you know about the different types of slots bonus and the terms and conditions, here are 5 points to help you find the right deal for you.
1. How much do you plan to deposit?
Choose a bonus that suits your budget. If you deposit just £10, don’t choose a bonus with a £20 minimum! And if you want to deposit £100, don’t choose a bonus that is capped at 100% up to £50, because you could be getting more elsewhere.
2. What wagering requirements come with the bonus?
Wagering requirements can vary wildly from one site to the next. Some free spins offers are wager free, but most match bonuses will have at least a 30x wagering requirement, and sometimes as high as 60x. Also check to see whether those apply to the value of the bonus only, or the deposit AND the bonus. There is a big difference!
3. What games do you like?
Make sure the bonus you go for is going to be eligible for the games you want to play. Remember, free spins are normally restricted to one game or a small group of games.
4. What is your deposit method?
If you are using an eWallet, find a casino that will pay out a bonus for your deposit. Remember, some sites restrict bonuses to Skrill and Neteller.
5. Expiry times
Finally, don’t get caught out by expiry times. If your free spins are only available for 24 hours, make sure you take them!
