Best First Deposit Bonus Slot Games
Slot sites are some of the most exciting on earth. They are fast-paced, colourful and provide plenty of opportunities to win real money. Big cash bonuses attract many of us to casinos; we love to have a flutter on various slot games.
In addition to the jackpots, you will also be able to yield the amazing bonuses that often come hand-in-hand with slot machines. That’s right- if you are new at a site, there is no doubt that you will be privy to some tantalising promotions.
The biggest bonuses are first deposit promotions. They require new players to sign-up and deposit using one of many payment methods; you’ll then receive a bonus amount.
Generally speaking, they are a 100% cash-match offer, but you will be able to unravel other deals.
Slots Bonuses for New Depositors
First deposit bonuses are obviously aimed at new players and there’s a multitude of generous offers all catered towards new customers. That’s a great thing because it means that as a customer you can roam different sites until you find a promotion that meets your preference.
Be sure to check out the different bingo payment options you can use.
Slot bonuses for new depositors are everywhere, and that’s because the casinos are trying to lure you in and gain your custom. Again, this is a good thing, because you can capitalise on the best bonuses from the top slot sites.

Once you’ve picked from the best promotions, it’s time to sign-up and make a deposit; you will soon be able to relish your promotion.
Making a deposit to an online slot is simple:
- Find the site with the best first deposit bonus.
- Click the link enter your details and sign-up.
- Upon joining, deposit the stake amount.
- You will then qualify for the promotion.
Wagering amounts can vary depending on the site and promotion. Be sure to check the minimum deposit amount that’s needed, the maximum deposit and the wagering requirements.
Deposit Bonus Wagering for Slots
As you can see, there are various types of first deposit bonuses available online.
Check out the offers on this page to find the best promotions around. You will have the pick of free cash bonuses, 100% cash-match and extra spins.
We have already found free spins for both Book of Dead and Starburst.
Here are some examples of various types of bonuses.
- Extra Spins- it’s always great to get risk-free spins, it enables you to take slots on a test spin. They are often bonus offers for Starburst slots. But you will find other ones too. Enjoy first deposit bonuses that throw in free spins.
- Cash Match- the most popular type of bonus that casinos offer, is usually a cash-match offer that requires a minimum deposit. Our bargain-hunters have managed to find you up to £500 in these types of promotions.

What to Consider When Looking For Slot Sign Ups
Here are some things for you to take into consideration when choosing your slot promo and slot game:
- What Slot Game? What slot game did you want to play and does the offer allow you to enjoy risk-free spins on that particular game?
- How Much You Plan to Deposit? If you don’t wish to deposit, then you will need to find a no-deposit bonus. Otherwise, you can find deals that allow £10 deposits.
- What Site is Best? Look past the initial welcome deal. Are there ongoing offers and is the site one that you’re likely to enjoy in future?
Types of Online Slots Offers
You can find many types of slot bonus offers. We generally find the welcome offers to be the most generous. Find out the different types of slot bonuses that you could get hold of, with our breakdown.
The type of slot offers includes the following:
- Free Spins- free spins is one of the most obvious bonuses. When you sign-up at many sites, they will provide you with free spins on a slot game. They are usually designated to specific slot machines. Learn more about how free spins work here.
- First Deposit Offer- the first deposit offer can be free spins, or it could be free cash to enjoy on the site. Use the bonus to play your favourite slot game.
- No Deposit Welcome Bonuses – a free offer for new players signing up.
- High Roller Match Bonus – promotions tailored towards high roller players at the site.
- Money-Back- if you deposit and lose your money, then you may be eligible to a percentage of it back.
- Ongoing Rewards- the best deals are ongoing ones; the top slot sites provide daily, weekly and monthly rewards for players that stake.
- Loyalty Programmes- similarly, loyalty and VIP programmes offer a chance for existing players to enjoy rewards.
Wagering Requirements of Online Casinos
It is integral to check the terms and conditions of all bonuses. Within them, you will find wagering requirements. These will need to be met before you can withdraw winnings. That is expected to be part of all promotions.
Read the small print for each promotion, as they can change between promotions. Every deal, such as free spins, comes with its own terms.
Free spins and free cash cannot be withdrawn until you win and stake a certain amount first.
For example, if you get a £10 bonus and the terms state that you need to adhere to the 40x wagering requirement. You will not be able to withdraw your winnings until you have staked the £10, forty times- that means you will bet £10 x 40. This equals £400’s worth of betting before being allowed to take any money that’s been won.
Slots Welcome Bonus No Wagering
There are some sites available which don’t have any wagering requirements on their slots offers. This means you can use the bonus and cash out any winnings straight away without having to wager a certain amount.
These no wagering slot sites are less common, but there are still some around that you can sign up with.
