100% Casino Bonus for Slots

If you want to find a casino with 100% casino bonus in today’s industry you don’t have to look far. Pretty much every online slot site has this welcome offer , so you can easily claim it and start playing right away. But this doesn’t mean that all of them are good enough to be claimed. You have to read the terms which come with it and see what the wagering requirements are, whether you get some extra free spins with the offer or does it have a maximum cash out limit.

Also some online casinos can claim that they have a 100% slots bonus, but when you make a deposit you find out that it’s actually a 50% on your first 2 deposits at the casino. This is why on this page I only have casinos which offer a real and good 100% welcome bonus in the FIRST DEPOSIT. The promos in this site are guaranteed to have favorable terms so you can claim them and start playing immediately.

My Top 5 casinos

Here is a list of my top 5 casinos which offer a 100% welcome bonus for slots. You can choose any of the promos you like and you can be sure that you will get your money’s worth.

  1. Barbados Casinos

    Barbados casino is a less known operator which I discovered by chance. But nevertheless they have a great 100% welcome offer which you can claim on your first deposit at the casino. In addition you will also get another 20 free spins on top. If you make a deposit on the second day after the first deposit you will get 40 free spins and another 40 free spins for your third deposit at the casino on the third day.

    The minimum deposit to claim the welcome bonus is only 10£/$/€, while for the rest of the promos it’s 20£/$/€. The amount will need to be wagered 35 times before you can ask for a withdrawal.

  2. King Billy Casino

    King Billy is a well known operator in the online gambling industry which has a great welcome bonus package. On your first deposit you can claim a 100 slots bonus up to 200. In addition you will also get 200 free spins, which are awarded in sets of 20 for the following 10 days. For your second deposit you can claim a 50% up to 200, while the third and fourth is a 25% match up to 300.

    In order to claim the second, third and fourth promo you will need to enter the codes WELCOME2, WELCOME3 and WELCOME4 accordingly. The wagering requirement for all of the promos is set at 35 times the offered amount.

  3. Yeti Casino

    Yeti casino is another great operator with an attractive 100% casino bonus. When you make your first deposit you get another 100 free spins. You can play them on the video slots Starburst or Book of Aztec by Amatic Industries. It can be claimed for making a minimum deposit of only 10 and comes with a wagering requirement of 40 times the amount.

    The only thing to look out for here is that deposits made via Neteller, Skrill and Ecopayz are not eligible for claiming the welcome bonus. So in order to make sure you claim it, the best way to go is with a simple Credit/Debit Card deposit.

  4. Zet Casino

    Zet Casino has a great welcome offer in their ranks. When you make a first deposit you will get a 100% match deposit bonus up to 500. As you can see this offer is also attractive for players who like to make bigger deposits and claim a bigger amount. The minimum deposit required to claim it is only 20.

    In addition to that you will also get a total of 200 free spins, which are added in sets of 20 for the following 10 days. The wagering requirement is set at 30 times to the total ammount.

  5. Red Spins Casino

    If you’re looking for a promo deposit 100 slot bonus Red Spins casino is the right operator for you. All new players in the UK can double their first deposit. Players outside UK (Germany, Austria, New Zealand, Canada, etc) will triple their money. The promotion is awarded only on your first deposit for a minimum amount of only 10. But you can also claim the maximum amount, if your bankroll permits it, and start playing with bigger bets on the games from the start.

    The wagering requirements at Red Spins are a bit high, set at 40 times the total ammount. But if the games are paying this shouldn’t be a problem. Check here for casinos with low wagering.

What is a casino welcome bonus?

A casino welcome bonus is awarded to the player on the first deposit at the casino. This is usually the best promo the casino has in stock, so it’s always a good idea to claim it in order to try the casino games. Some of the most common welcome promos at online casinos are the following.

Types of 100% casino bonuses

  •  Match Bonus

This is a promo where the casino will match the amount you deposited. So for example, some casino has a 100% match bonus for slots up to 200. If you make a 100 deposit you will get another 100 from the casino as a gift.

If you deposit 200 you will claim the maximum 200 and so on. At some operators you can even make a bigger deposit, but you will only receive the maximum amount, in this case 200.

  • Cash back bonus

A 100 casino cash back bonus is just what it says it is. When you make a deposit at the casino and lose it, the casino will match the deposit in cash back. So in fact with this promo you have a chance to play twice at the casino with the same deposit amount.

This promo is attractive since it offers you an insurance on your deposit. The only downside is that the cash back bonus will certainly come with a wagering requirement. This means that if you made a big deposit the attached wager to the cash back will now, without a doubt, be very big as well.

  • Bonus for new slots

A 100% bonus for new slots is more likely to be found in the reload promos than in the welcome ones. This type of offers is usually awarded to regular players at the casino. In most cases you can expect to receive it when the casino adds games from a new software provider in their portfolio.

This is a great way to try the new casino games with some extra money, especially since it’s quite hard to find a reload bonus at your regular casinos.

Can I find a promo deposit 100% bonus in UK Casinos?

Yes, in general it’s still very easy to find a 100% casino bonus for slots in UK casinos. But what you should know is that promos like this are decreasing by the day. The recent regulations in the UK mean that the taxes which casinos pay are really high.

So many operators are simply moving to some cash back of free spins promos instead. But you will still be able to find a 100 slots bonus across UK casinos in the future as well. There are a big number of really strong UK casinos, who simply don’t care about taxation and want to make their players happy. In the end if the players are not happy the casinos will stop generating revenue.

Watch out the hidden terms

By now you already know that pretty much every 100% casino bonus for slots, or any other similar to it, usually comes with some terms and conditions attached. The terms of the welcome packages will need to be honored to the letter or the casino can legally void your winnings. Let’s take a look what are some of the most common hidden terms you can come across when claiming a promo deposit 100 bonus at online casinos.

  • Minimum deposit amount to claim the bonus

    This is usually a pretty straightforward term when it comes to welcome packages. But at some casinos you can see that the minimum deposit amount is set at 10. At the same time in order to claim their 100% slots bonus you will need to deposit 20 or even more.

  • Allowed payment methods

    At many online casinos today the fine print of the 100% casino bonus terms claims that Skrill, Neteller, PayPal and Ecopayz are not allowed as payment methods for claiming it. It’s very frustrating to learn this only after you make a deposit and you don’t see the extra money added on your account.

  • Allowed and forbidden casino games

    Every casino welcome package has a maximum allowed bet per spin limit. It’s put in place for the casino to protect itself from players who can win a lot of money, simply by using the extra funds. At most casinos you are limited to placing bets up to a maximum of 5 per spin or hand, but this value can differ from one casino to the other.

  • Wagering requirement

    The wagering requirement is also pretty much a simple term. Every promotion will come with a certain wagering requirement attached. But the trick some casinos use here is in the games wagering contribution. In most cases slots contribute 100% towards the wager, but at some operators it can be 75% or even 50%.

  • Account verification

    With the latest changes in UK legislation all players are required to send in their documents and verify their casino account before they start playing at the casino. So if you’re a UK player and come across a new casino make sure to get this done first, before you make a deposit and claim a bonus at the casino. You can easily deposit and claim the bonus, but you won’t be allowed to play until the verification is completed.

  • Misleading promos

    Misleading promos are very frustrating and they are a prime example why you should always read the terms before you claim any kind of promotion. Some casino can advertise a 100% bonus up to 1,000 as a welcome package. So, you make a deposit of 1,000 and see that only 500 in extra money were added to your account. When you read the terms you see that it is in fact a set of two 50% match deposit bonuses up to 500.
