Online gambling has grown into a multi-billion pound industry and it shows no signs of slowing down anytime soon. Operators are always launching new online casinos, sportsbooks, poker and bingo sites. The beauty of having so many operators within the same industry is that it creates a lot of competition, encouraging them to find new and exciting ways to attract players.

One method that operators use to attract new customers is offering bonuses. So, whether you like roulette, slots, Texas hold’em or you prefer a punt on the horses, we’ll give you a run-through of the types of bonuses you can pick up. Plus, you can check out our list of May 2021’s top gambling sites offering some stellar bonuses.

Casino Bonuses

Claim a Casino Bonus

Bonuses are a great way to get started at an online casino. You can use your welcome offer to get familiar with your chosen gambling site and even try out some new games without using your real money balance. Let’s take a look at some of the most common online casino bonuses

Matched Deposit Bonus

The matched deposit bonus is one of the most common bonuses awarded to players after creating a new account. When new customers claim this welcome offer, the casino matches their initial deposit, as the name of the bonus suggests. A common matched deposit offer would be ‘100% up to £100,’ which means that you can double the size of your cash pot up to the value of £100. If you deposit more than £100, however, you won’t be rewarded with anything extra. If the bonus requires a promo code to activate it, make sure you also know what it is as you won’t be able to claim the bonus without it. 

No Deposit Bonus

Some casinos allow you to claim online casino bonuses before you’ve made your first deposit. Some of the best online casinos offer no deposit bonuses — a great way to try out a new gambling site, with no strings attached. As the name implies, you won’t need to spend a penny to claim these rewards. While these aren’t the biggest bonuses, usually 20 free spins or a free £5, they do serve as the perfect appetiser to give you a taste of real money gambling.

Free Spins

Free spins are the quintessential slots bonus, giving those who love to play the reels some great free slot action. New customers, as well as existing players, can claim free spin bonuses so the fun of trying to hit the jackpot can be had by all. Free spins are a great way for players to try out the best new titles from innovative software developers such as NetEnt, Microgaming and Scientific Games. Unlike a deposit bonus, free spin wagering requirements will usually apply to the winnings you make from them. So if you make £20 from a free spin bonus that has rollover requirements of 30x, then you would need to wager £600 before you can claim your winnings. 

Reload Bonus

Existing casino players needn’t miss out on offers, either, thanks to casino reload bonuses. These reward players for topping up their casino balance, but the way they’re rewarded will vary from site to site. Some casinos will offer deposit match reload bonuses, while others will gift players free spins.

Cashback Bonus

Given that casino games are mostly down to chance, it is likely that you will encounter some bad luck and make a loss. Cashback bonuses are the perfect way to make back some of these losses. Casinos usually offer a percentage match up with a limit. For example, you might see a cashback offer of ‘20% up to £100 on slots’.

On top of these bonuses, many online casinos offer prize drawers and VIP clubs, so there are plenty of ways that existing players can continue to get a bankroll boost.

Finding a bonus that suits you can really enhance your sports betting experience so let’s delve into the most common options available.

Matched Deposit Bonus

While this promotion is most common at online casinos, there are a few bookies that offer matched deposit bonuses. Players make a deposit and the bookmaker will match a percentage of this in playable funds. Just like casino bonuses, these often come with a cap in terms of how much the bookies will pay out. For example, you may see an offer of ‘100% up to £50’. This means that, if you deposit £40, you’ll have £80 in playable funds. However, if you deposit £60, you’ll have £110 in playable funds, because the operator will pay out a maximum of £50. Some matched deposit bonuses will require you to enter the bonus code so it’s important that you use this to activate the promotion.

Free Bets

This type of bonus is exactly what it sounds like. Bettors have the opportunity to place a bet without wagering any of their own cash. Much like any other bonus, free bets will often have terms and conditions that affect your initial wagering and ability to redeem any winnings. As such, we would always recommend reading the full terms and conditions of any bonus you’re interested in before you claim. 

Bet x Get y Bonus

The ‘Bet x Get y’ bonus is another form of free bet, but one that requires you to lay a qualifying bet first. For example, you may see an offer of ‘Bet £10, Get £30 in free bets.’ There are usually restrictions placed on your bonus funds, such as the markets you can bet on and the minimum odds of bets you can place using these funds. These are in place to limit your chances of winning with your free stake. 

Bet Insurance

Some online betting sites offer bet insurance as part of their welcome bonus package. Bet insurance promises bettors a refund if their bet doesn’t pay out. You’ll usually be required to wager a minimum amount, and there will be a limit on how much your chosen bookmaker pays out. However, this bet is great for first-time punters or those new to sports. Paddy Power currently offer a similar welcome bonus, giving customers a ‘risk-free bet’ after they make a minimum first deposit of £10. If the risk-free bet loses, then Paddy Power will refund the bet in cash up to the value of £20. 

Sportsbook bonuses differ from casino bonuses in that bookies tend to offer more promotions to existing players. These promotions might include enhanced trebles and insurance accas, as well as free bet clubs and loyalty schemes.

Poker Bonuses

Boost Your Poker Bankroll

It doesn’t matter whether your preference is for more established poker sites like 888poker and Unipoker, or for the freshest names such as GGPoker, all will offer new customers exciting welcome bonuses. Here’s a brief rundown of the different bonuses available. 

Matched Deposit

Poker sites offer some of the most lavish bonuses available online, and matched bets are one of the most common among these. Whereas an online casino might offer 100% up to £300, a poker site could offer 100% up to £1,000. GG Poker goes some way to matching this offer with a welcome bonus of 200% up to £600. 

Freeroll Bonus

This is one of the most common poker bonuses. While the daily freeroll might be a modest £20, a Sunday night game might offer £250, and monthly prize pots might reach £5,000. Some freeroll bonuses have entry criteria, sometimes only allow recent depositors to claim, but others are available to all, free of charge. Whatever the size of the prize pot, poker freerolls are a great chance to win some money without risking any of your own.

No Deposit Bonus

The no deposit bonus is exactly what it seems as you can claim some bonus poker funds without having to make an initial deposit. These are often seen as some of the best value bonuses around, but make sure you’ve read the full terms and conditions before you opt in — the rollover requirements may be more stringent than with other bonuses. 

On top of these bonuses, some poker sites also offer guaranteed prized tournaments. These aren’t freerolls, but they offer a huge payout and players can enter through qualifying events for just a small sum of money.

Bingo Bonuses

Look Out for a Great Bingo Bonus

Bingo is one of the world’s most popular games and there are some incredible sites out there that allow you to play a huge variety of bingo game types. Welcome bonuses and existing player promotions can be a great addition to your time at a bingo site, with the best value offers a perfect way to enhance your experience. 

First Deposit Bonus

First deposit bonuses are an incredibly common bingo welcome bonus and new players can claim them in one of two ways. Customers can either claim them as a matched deposit — where a certain amount of cash is added to your bankroll depending on the size of your initial down payment — or as a fixed bonus amount which you will receive when you meet the 1st deposit amount. 

‘Spend and Get’ Bingo Bonus 

The ‘Spend and Get’ bonus is pretty similar to the first deposit bonus, in that you receive some bonus funds after making an initial deposit. But the key difference here is that you must first spend your deposit on a set amount of bingo tickets before you receive the bonus amount. Always check the bonus terms and conditions before you claim just in case there are any other terms and conditions attached to the bonus. 

Free Bingo Tickets 

In the same way that betting sites and casinos will offer free bets to customers, bingo sites will give out free bingo tickets to their new and existing customers. These can be given out right off the bat, or you may have to deposit a set amount beforehand. Free bingo tickets are also often tied to specific games, so make sure you read the terms and conditions before you opt in. 

Terms and Conditions

Mske Sure You Read the Fine Print

When you claim a bonus, there are likely to be terms and conditions attached to it that will have an impact on how you play. From how much you must wager, to how much you can actually win. Let’s have a look at the key terms and conditions you should be aware of before you claim a bonus.

Wagering Requirements

Wagering requirements stipulate how much of your cash you must wager at the gambling site before you can claim any winnings you may have made from the bonus. The amount you must play through is decided by the gambling site and is generally the bonus amount or the size of your winnings, or a combination of the two. So if you signed up for a bonus with wagering requirements of 35x the bonus amount, and you claimed £20 in bonus funds, then you would need to wager £700 (35x20) in order to get your hands on any winnings you made with the bonus.

Time Limits

While bonuses can provide a lot of fun, no offer will last forever. Some bonuses will come with generous time limits, running for over a month once claimed. Others, however, will have far stricter time restrictions such as just 24 hours. Once the maximum day expiry has passed, the bonus will no longer be valid and any winnings you may have made will be lost. The best value bonuses will give you more time to fulfil the rollover requirements, so make sure you’ve read the full terms and conditions before you claim.

Payout Limits

When you claim a sign-up bonus, it will more than likely come with a maximum redeemable amount. Gambling sites are businesses at the end of the day and are designed to make a profit, so it’s understandable why payout limits are enforced. As a bettor, however, you should always make sure that the maximum bonus is worth it — you don’t want to spend more than you are able to win. Bonuses also come with minimum deposit limits. So in order to be eligible for a promotion, you must lay the minimum deposit amount first.

Restrictions

There are usually restrictions in the terms of conditions that limit which games or markets you can redeem your bonus on. For all casino, poker or bingo bonuses, you will find that a bonus is only available for use on selected games. Similarly, for betting, you’ll usually find terms and conditions outlining the minimum odds that your wager has to be in order to redeem your free bet.

Mobile

Claim a Bonus from Your Mobile

Gambling via your mobile phone is the most popular way to bet nowadays with the best betting, casino, poker and bingo sites all offering their customers excellent native apps that can be downloaded to their iOS or Android devices. As such, it is also possible to claim a bonus from your mobile device and then play through the wagering requirements all from the palm of your hand. Not every site we’ve featured on this list will have a mobile app that customers can download, but all will at least provide a mobile site that players can access from their browser.

New Sites

Try Out a New Gambling Site

The best betting experiences aren’t always found at the best-known betting sites. 

In fact, some of the newest sportsbooks, casinos and bingo sites offer some of the best online betting experiences available. 

Player-friendly bonuses are a regular occurrence at new gambling sites, while innovative promotions and beautifully designed websites will make sure your stay is always enjoyable.

Pros

  • Player-friendly bonuses
  • Exciting promotions
  • Beautifully-designed sites

Cons

  • Many won’t have a mobile app
  • There could be a lack of special features such as live streaming or cashout

Banking

Deposit and Withdrawal Methods

Finding the right banking method is pretty important when you’re claiming a gambling bonus. You’re going to want to make sure that the gambling site you choose allows you to deposit and withdraw with your preferred payment methods. Let’s take a look at the some of the most common methods available at online gambling sites.

Debit Cards

Debit cards are by far and away the most popular payment method for online punters, with most customers having access to one through their bank account. Deposits are generally instant and all your card payments will be protected by the best data encryption software around. There can be a long wait on your hands when you withdraw using a debit card as payouts can take between one to five working days to process. It’s best to look out for sites that offer Visa Fast Funds, as by using this service, customers can withdraw their money within four hours.

E-wallets

E-wallets are a great option for many punters looking to withdraw their cash quickly. Using services such as PayPal, Skrill and Neteller can mean getting your hands on your cash in as little as 24 hours, while safe in the knowledge that all your transactions are protected by industry-standard data encryption software. You may run into some issues when claiming a bonus, however. Some e-wallets are excluded from certain bonuses which means that you will have to use a different method in order to sign up to it.

Prepaid Cards

Prepaid cards are the ideal deposit method for those whose primary concern is security. You can buy a Paysafecard voucher in one of many denominations by using real cash at a brick and mortar store. As such, you don’t need to share any bank details when depositing your funds. You will, however, not be able to withdraw your funds using a Paysafecard and will therefore need to use a different payment method to get your hands on your cash.

Cryptocurrencies such as Bitcoin are growing in popularity across the world, but you will struggle to find a UK casino that supports the payment method.

Responsible Gambling

How to Keep Your Gambling Safe

Signing up to a bonus can really enhance your playing experience, but you should always make sure that you gamble responsibly. All gambling sites licensed by the UK Gambling Commission (UKGC) must incorporate tools that players can use to stay in control, such as time and deposit limits. 

If you feel like you need to take a more prolonged break from gambling, then you can sign up for a self-exclusion scheme, such as the one provided by GAMBAN. These will allow you to ban yourself from all UK-licensed gambling sites for a period of up to five years. 

There are also a number of great charities that can help give you advice and support, such as begambleaware.org. Begambleaware provides a wealth of helpful information that problem gamblers can follow to stay on top of their addiction as well as offering the 24/7 National Gambling Helpline.

Your Questions Answered

Can I claim multiple welcome bonuses from the same operator?

You can’t claim the same welcome bonus more than once but, if an operator offers additional bonuses, you’ll usually be able to claim these on top of the welcome bonus. Some casinos will restrict the number of bonuses you can claim at once, so be sure to check for this in the terms and conditions.
