Frequently Asked Questions

What is a deposit vs no deposit bonus?

Simply put, deposit bonuses require you to make a minimum deposit to claim a reward, whereas a no deposit offer credits your bonus on registration. Some sites offer both to encourage you to sign up and then deposit at a later date.

While a no deposit bonus may seem more appealing on the surface, most come with restrictive terms and conditions. However, if you find a site offering both, you can maximise your bonuses and increase your initial bankroll at a new casino.

How do I claim a casino bonus?

Welcome bonus rules vary between sites. Some are straightforward and don’t require any extra effort – just sign up or deposit and the reward is credited to your account automatically.

Alternatively, some casinos require you to enter a promo or bonus code. This is common for casino brands that host a variety of products, such as sportsbook and bingo, and where more than one welcome bonus may be available to new players.

In cases like this, you will probably need to enter the code during registration at the site or at the cashier, to claim the casino-specific welcome offer.

Always read the terms and conditions before signing up to a casino to avoid losing out on a bonus over a technicality.

What’s the difference between a real money and bonus wallet?

Most casinos have two separate wallets to manage your real cash and bonus funds. The names vary between sites but they are mainly categorised as a withdrawable and non-withdrawable wallet.  

Your real money wallet holds your unspent deposits, winnings and any profit from a bonus where you’ve satisfied the wagering requirements. All cash in this wallet is available to withdraw at any time, subject to minimum withdrawal limits.

Your bonus wallet contains funds you’ve been awarded from a promotion such as a welcome offer or loyalty bonus. These funds are limited to promotional terms and conditions and are only transferred to your withdrawable balance once you’ve met the requirements.

Can I withdraw my deposit after claiming a bonus?

You can withdraw the cash in your real money wallet at any time, subject to restrictions set by individual casinos.

Before claiming a bonus, check the terms and conditions as your bonus cash and any winnings may be forfeited if you haven’t satisfied the wagering requirements at the time you withdraw your initial deposit.

Some bonuses use your deposit funds before accessing the bonus cash, so be alert and know which wallet you’re wagering with. If you play through your cash and decide you no longer want your bonus, you won’t be able to refund your deposit.

Why go for a casino bonus when there are wagering limits?

While wagering limits can be a nuisance, as you don't necessarily get to enjoy the full amount of your winnings, they allow casinos to offer heftier promotions to their players. They also allow you to play for longer with your deposit. If you deposit £10 and get a huge £50 in bonus funds that's £60 to play with! While you can't immediately withdraw that £50 you still get to play with that bonus money as if it were real money you deposited.

Simply put, a casino bonus promotion allows both the casino and you more bang for your buck. Once you have met the wagering requirements you can withdraw your winnings as real money, and the casino is able to continue offering these huge bonuses.

  3. Types of casino bonuses
  4. Things to watch out for
  5. Which bonus should I choose?

Online casino bonuses are a great way to stretch your deposit to play for longer at a new site. Casino brands use attractive promotions to be noticed in a competitive space and incentivise new players to join their websites and deposit – depending on the offer.

With so many varieties to choose from, it can become overwhelming and difficult to understand what a casino is offering, how to claim a bonus and which deals are the best.

This guide will help you learn how to be a bonus expert and while casinos also offer promotions for existing customers, here we’ll focus on bonuses exclusively for new players.

An explanation of wagering requirements

A wagering requirement is a multiplier that represents the number of times you have to play through a bonus before you are able to withdraw any winnings.

For example, if you deposit £50 at a casino with a 100% match bonus and 35x wagering requirements, you’ll need to wager £1,750 (35 x £50) before the amount transfers to your real money balance.

Games do not always contribute to wagering requirements equally. Contribution can range from 100% for slots, to as low as 10% of each wager for selected table games, such as roulette.

Why have wagering?

It would be financial suicide for a casino to offer £100 cash to every new customer, no strings attached. Wagering requirements protect casinos while allowing them to offer huge match deposit bonuses or hundreds of free spins to new players.

There is also a more legitimate reason for their existence. Online casinos must comply with anti-money laundering regulations, so wagering requirements work as one method to prevent criminals from cleaning illegal funds by depositing and withdrawing the cash immediately.

However, it’s not entirely necessary to impose wagering requirements to stay compliant as no wagering casinos manage it with identity check, due diligence and funds verification. For the most part, they exist to prevent too many players profiting from the bonus and walking away with the money.

Types of casino bonuses

Now that you’ve got to grips with the complicated business of wagering, it’s time for the fun bit – casino bonuses.

Bonus funds

The most common type of casino bonus takes the form of non-withdrawable funds stored in your bonus wallet, usually presented as a percentage matched deposit offer.

For example: Get 100% up to £200 means if you deposited £200, you’d have your original £200 + £200 bonus cash = £400 total. You can also claim the bonus on a smaller deposit.

The bonus cash is playable across most games, however, it’s usually limited to slots and a handful of table games. Also, you’re typically required to play through your deposit before your bonus balance kicks in.

Some casinos like 888Casino offer bonus cash upon registration which is usually subject to high wagering requirements and limited to certain games, often excluding table games like roulette and blackjack.

Casinos like mFortune, Mr Spin and Tombola Arcade offer no deposit cash bonuses with one-time wagering which means anything you win is credited to your withdrawable balance. However, these bonuses are very rare so if you find one – grab it!

Free spins

Many casinos offer free spins on popular slot games with a predefined stake. The spins are typically restricted to one game and subject to either high wagering requirements or capped winnings.

Some casino brands like bgo, PlayOJO and mFortune are breaking the mould and offering free spins with all winnings paid in withdrawable cash!

Your free spins should be available to play after triggering the promotion and upon opening the game, you’ll get a clear message indicating your spins are free.

Once you’ve used your free spins, another notification will appear informing you that all subsequent spins will use your real bonus funds.

Time-limited free play bonus

Some casinos offer a starting balance for players to spend within a shorter time frame than a traditional cash bonus, generally up to an hour. After that time, all winnings over the initial balance are yours to keep once you’ve fulfilled the wagering requirements.

Keep in mind that free play bonuses are only triggered upon meeting a minimum deposit amount, which may be larger than the site’s overall deposit limit, plus winnings are usually capped.

This offer used to be very common on Microgaming-powered casinos, however, it’s been replaced by a match deposit bonus and we’ve not seen another network run this type of promotion.

What to watch out for

Casino bonuses may look attractive at first, but it’s only when you read the terms and conditions that you’ll find out whether an offer is too good to be true.

Time restrictions

Most casino bonuses have a time limit. You may only have a couple of days before free spins expire or a week to spend your bonus funds. Similarly, bonuses with wagering requirements often set a period within which you have to fulfil them before you risk losing your winnings.

Limited games

The majority of online casino bonuses are available to use on selected games only. While this is expected for free spins, it’s worth also checking when you accept a bonus amount because table games like roulette are often excluded from many welcome offers.

Capped winnings

Some casinos cap how much you can win on a bonus to reduce the risk of players hitting a slot game bonus round and winning thousands on their first spin. Such caps vary from just a few pounds to more substantial amounts; some no wagering casinos don’t have caps at all.

Which casino bonus should I choose?

Finding the best online casino bonus for you is often a case of personal preference and the size of your budget.

You may assume that a no deposit bonus is favourable, but most are subject to high wagering requirements and are normally less generous than their deposit-led counterparts.

No deposit bonuses are ideal for players wanting to try out a site before committing their bank details. On the other hand, if you are confident you want to deposit, a deposit-led cash bonus is usually larger could be a better option for you.

Alternatively, some seasoned casino players avoid claiming bonuses altogether, preferring to play with their own money to avoid capped winnings and the frustration of wagering requirements.

It’s also worth considering a no wagering online casinos. While the bonuses aren’t as attractive as huge match deposit bonuses, you’re more likely to retain a profit if you win thanks to significantly fewer terms and conditions.
