Types of 100 percent casino bonuses
The 100% casino bonuses come in different shapes and forms. Some credit money into your bonus balance, others offer you free spins and with some you'd be able to play on various live casino games and so on.
First deposit bonus
Usually a 100% bonus match will be credited on your 1st deposit which has, of course, a min limit and a max limit. For example, it might be a bonus up to £100 credited when you make a deposit of £10 at least.
Casino welcome bonus package
Those are promotions which are crediting you a certain part of the bonus on each of your first few deposits. It might be 100% up to £100 on first deposit, 100% up to £300 on second and another percentage match of free spins on your third one. A great variety is available here and many of those promo offers amount to an even higher total percentage bonus.
Free spins
Almost all casinos in the UK offer you some free spins, too. They also require you to credit a certain minimum deposit amount into your wallet and can come in varying amounts. For instance, you might be able to get 25 bonus spins on your 1st deposit or you might be offered 50 bonus spins on Big Bass Splash when you deposit £10 into your casino account.
Free bets for live games
Another first deposit offer that a given casino might offer you is the one for live dealer games. For instance, some sites offer a 100 percent match on your first deposit up to £100 bonus which you can roll over on blackjack, roulette, game shows, etc.
Reload bonuses
You can claim plenty of bonus funds on a next deposit, too. That's something called a reload offer. In other words, a promotion credited to you after you've topped up your account a certain number of times and now you're doing it again.
Bonus terms and conditions: What should you know about wagering requirements?
Before you make your first deposit and claim your 100% match deposit bonus, you'd need to be familiar with the terms and conditions of the offer. And let's take a quick look at those.
Min deposit amount
You'll have to make an initial deposit that's equal to or above a certain max limit. This might be a min deposit £20, a £10 one or as low as £5. The bonus cash won't be offered on some types of deposits, though, usually those made with Skrill or Neteller.
Maximum bonus
With all sites that allow you to get a 100 percent match on your first deposit, you'll see a max bonus rule. For instance, some promotions give you up to £100 while other online casinos offer you a bonus up to £300.
Eligible games
Usually the cash bonus can be used on lots of the slots within the casino section while the free spins are either credited to one specific game only or to several eligible games. You can check those out within the terms and conditions of the bonus.
Rollover
The most common rollover rule that you'll find is 30x or 35x the deposit and bonus amount and 60x the free spin winnings. Those conditions can vary a lot, though. With some sites you won't have any rollover required. Or there might be some promotions where the bonus funds are separate and you don't have to wager the deposit funds. Yet, most commonly you'll need to roll over both the deposit, bonus and free spin winnings within a certain time frame.
Validity period
Another important rule that you'll need to check is how long is the bonus valid. This might be quite a long period or just a short one. For instance, some sites offer a bonus valid 30 days while with others, especially if you're claiming free spins, you'll need to use them and roll them over within a much shorter time frame that can vary between 24 hours and 7 days.
Max bet while wagering with an active bonus
Usually when you claim any promotion, while you're wagering it over, you won't be able to place a bet over a certain max limit. That's usually 10% of the free spin winnings and bonus amount or £5 (whichever one is higher) for the occassions where the bonus is available for slot games. Promotions credited for live dealer tables might have higher max bonus bets.
Max bonus converted to real money
After you play through the bonus, you won't be always able to get all of your winnings out. Many gambling sites have a max amount convertable to real money rule. Most frequently that's 3 times the bonus amount and any cash over that limit will be deactivated.
How to sign up and claim a 100 percent deposit match bonus?
In order to claim the bonus money available for new UK players, you'll need to sign up and credit some money into your deposit balance. That's available though the respective registration button which leads you through the sign up form. Once you've completed that and you've confirmed the account creation, you'd be able to make your qualifying deposit.
Check the promotion's rules, though, in order to see what's the min deposit for the bonus to be available and what's the max amount of money you can get. Keep in mind that if you'd like the max sum, you'll have to credit just as much money into your account. For example, you'd need to deposit £100 in order to get the maximum amount of a deposit bonus up to £100. Or if you'd like to claim £50 in bonus cash, you'll have to top your account up with £50.
On some occassions you'll have to place a qualifying wager before the bonus being credited. That's usually when you're going to be claiming some free spins and most commonly the requirements is to wager £10 on slots. With most promotions, though, the bonus spins are claimable on a qualifying deposit.
Games you can play with a 100 percent match casino deposit bonus
When you've claimed your 100 percent bonus, you'd be able to play it on a wide variety of games.
Popular slot games
Those are usually the only games which you'd be able to play and we recommend wagering the total bonus on them even when other games also contribute to the rollover because they live dealer tables, if eligible for play, often credit you only 10% of your bet towards the wagering. When it comes to the slots, though, you've got an enormous collection of opportunities. Titles by Pragmatic Play, Microgaming, Play'n Go and other top-tier providers are all available. Fruit themes are still abundant but you'd be able to play on mythology-themed games, too, as well as on some who've got fishing as their main topic or are based on animals, adventures, fantasy, mystery, horror and so on. Plenty of Megaways slots are on the table, too, and same's valid for the extra bonus features available, like multipliers, free spins and so on.
Jackpots
Jackpot slots aren't eligible for playing on with some of the welcome bonuses but the casino sites that offer 100% deposit match feature many of those games. They feature progressive jackpots in most cases while some titles have a fixed amount you can win. The themes and bonus features also differ quite a lot.
Table games
Different table games are offered on the best casinos with 100% match bonuses, too. They include roulette, blackjack, poker, baccarat and many, many others. Still, in most cases you'd be able to play them with real funds only and not with a welcome bonus.
Live casino games
Other exciting opportunities that allow you to have a great amount of fun are the live casino games. Blackjack, poker, game shows... and many others are streamed live and led by real dealers. That brings you closer to the land-based casino experience and allows you to socialize with other players, too.
Payment methods on the best online casino sites offering 100 percent match bonuses
If you'd like to claim a match bonus, you'd need to make a deposit first. And that's available though various payment methods, such as:
- Visa and Mastercard debit cards
- Paypal
- Open Banking
- Wire transfer
- Trustly
- Apple Pay
- Google Pay
- Crypto
Many casino sites offer Neteller and Skrill as banking options, too, but deposits with them don't allow you to claim any bonuses.
Can you claim a 100% first deposit bonus casino offer on mobile?
Yes, you'd be able to easily claim your first deposit bonus offer on your phone, too. You simply need to log into the casino site on mobile. While some gambling platforms have dedicated apps, with others you'd be able to play through the browser. We always recommend the second option because it doesn't require any downloads, it doesn't take up any space on your phone and it doesn't need frequent updates.
And once you've opened your browser, entered the casino and logged in, you'd be able to make your deposit on mobile, too. Check when you should opt-in for the bonus, activate the offer and follow the steps required. Once you've completed them, your bonus will be credited automatically.
Alternatives to casinos with a 100 percent first deposit casino bonus
There are various alternatives to the 100% first deposit match. Many of them are found quite rarely but are offering you even better bonus terms. Those are:
- 200% deposit match bonuses
- 300% deposit match bonuses
- 400% deposit match bonuses
- 500% deposit match bonuses
Such promo offers give you even bigger amounts to play with on a lower deposit but wagering requirements might be a bit heavier.
