How to play games at casinos with a 100 bonus
Games are the reason you visit online casinos. They provide you with entertainment, offer a chance to test your skills against a dealer, fellow players or a computer and give you an opportunity to earn some cash — if you have a successful betting session.
We want you to have the most fun possible when you’re playing casino games. That’s why we’ve included below some tips on how to play the most popular ones you’ll find at casinos with a 100 bonus.
How to play slots games at the top gambling sites with a 100 deposit bonus
Slots are games of pure chance. You’re just as likely to win or lose when you make your first bet as you are when you make your one millionth.
This means that you should play slots for fun, picking ones that you like and not those you believe to be either tight or loose.
How to play roulette games at the top gambling sites with a 100 deposit bonus
Roulette is a casino classic, with its spinning wheel a gambling icon. Our key advice to help you play roulette is to know which variant you want to play, with American roulette and European roulette being the two main types.
American and European roulette are pretty similar but they have one important difference. The difference is in the number of green zero pockets they have.
There are two green pockets in American roulette, but European roulette has just one zero pocket. This affects the house edge, with American games having an edge of 5.26% and European games having an edge of 2.30%.
So, our advice is that you give careful consideration to which type of roulette you play, as it will affect your chances of having a winning session.

The basic blackjack strategy helps you to make the optimal plays at any given moment during a game, giving you tips on which of the following moves to use:
Hit or stand
By learning this strategy, you can give yourself a better chance of making the right moves at the right times and having a more fun blackjack session.
What is a 100 per cent deposit bonus?
A 100 per cent deposit bonus is a casino offer that will reward you by crediting your casino account with the same amount of money you’ve deposited.
For example, if the offer was 100% and you deposit £100, the online casino will match this amount and your account will show a balance of £200 — assuming it had a balance of zero prior to you making your £100 deposit to get the bonus.
One important thing to be aware of with a 100 per cent deposit bonus is that there are often limits on the amount you can invest.
For instance, a casino may set a limit of £250, which means the bonus would only be valid for deposits of up to £250.
Other welcome bonuses available at casino sites
It’s no surprise bonuses are offered by pretty much every major online casino that’s available to UK players. Bonuses give gamblers an opportunity to play more of their favourite games, which means they spend more time using their favourite casinos.
To get the most out of bonuses, you need to know which ones to be aware of and what they offer to you. These are the main casino bonuses:
Free spins are bonuses that are exclusively for slot games. As the name suggests, they offer free plays (spins) on leading slot titles. These offers may have a credit max free spins restriction, which means you might be limited on the number of free plays you’re credited with at a given time.
Cash welcome bonus
Unsurprisingly, cash welcome bonuses present an opportunity to earn some extra money to use on your favourite casino games. These bonuses can generally be used on any game of your choosing and often require you to make multiple deposits to get the full amount.
No deposit bonus
No deposit bonuses are a generous rarity for gambling fans. Unlike most casino rewards, no deposit bonuses don’t require you to invest any of your own money to be able to withdraw the winnings you make from using them.
Bonus terms and conditions
Every casino bonus must display the terms and conditions of its use. This is to protect players from the risk of hidden requirements that would change the quality of the reward they’re signing up for.
You can find the T&Cs of casino bonuses in the advertisement for the rewards. They’re usually very simple to spot because they’ll be labelled “T&Cs” or “terms and conditions”.
It’s important to read the terms and conditions of any offer you sign up for because they explain what you need to do to get the free spins, welcome bonus or 100 deposit bonus you’re signing up for.
These are some of the things you can expect to see in bonus T&Cs:
Bonus winnings limits: the max free spins winnings you can cash out from an offer.
Minimum deposit requirement: the amount of money you must deposit to be eligible for a bonus.
Bonus valid or free spins valid date: any time restrictions on a reward.
If bonus funds count towards your winnings: if you can collect any bonus funds and if you can then the amount you can cash out.
Bonus spins credited only to specific games: where you can only use free spins on certain slots games.
20 max bonus bet: you can only bet a maximum of £20 at any one time using your bonus funds.
Why you should keep bonus funds separate to cash funds
You should only ever play casino games to have fun and responsible gambling is your guide to ensure this happens.
Responsible gambling is about betting within your means and managing your money in a way that allows you to do so. This is why it’s important your bonus funds are separate from your personal cash wagers.
The reason for keeping bonus money separate is it allows you to keep a check of how much you’re actually spending on casino games, so you can be sure you’re keeping to a responsible limit.
What are bonus wagering requirements and how do they work?
Wagering requirements are super important when it comes to choosing casino bonuses. The reason they’re so important is that they’re the amount of your own money you need to invest to be able to withdraw the winnings you make using bonus funds.
Wagering requirements are a simple equation that’s represented as a number followed by an x. This is to show the number of times you need to wager the value of the casino offer before you can collect your bonus money.
To help you get a picture of how these requirements work, underneath you can see how much money you’d have to invest for a £100 welcome bonus with a variety of wagering requirements:
Wagering requirements of 20x: you need to invest £2,000 of your own money
Wagering requirements of 40x: you need to invest £4,000 of your own money
Wagering requirements of 60x: you need to invest £6,000 of your own money
Reasons to choose a 100% match deposit bonus
Choosing the right bonuses is important. Bonuses provide you with an opportunity to earn some casino credit, boost your account balance or get a few free spins.
Each bonus offers something different and you need to decide what you want from your casino rewards. 100% deposit match bonuses are among the best offers you can get from online casinos and there are a few key reasons to choose them, including:
Keeping to a responsible gambling limit
Getting some extra casino game plays
Doubling your deposit amount
How to claim a 100% bonus?
Online casinos make it incredibly easy for you to claim a 100% deposit bonus. They do this because they want you to deposit your cash and then use it on their games.
While each casino will have its own bonus application process, most sites require you to follow a set of instructions that will closely mirror these ones below:
Locate the 100% deposit bonus
Sign in to your account/create an account
Read the T&Cs for the bonus
Deposit your money
Receive your bonus funds
Banking options at gambling sites
You should rightly take it as a given that you should have plenty of banking options available to you, regardless of the gambling site you select.
Most online casinos offer all of the major deposit and withdrawal methods and providers, with the below options generally included as standard:
Fast Bank Transfer
Citadel Instant Banking
However, you do need to keep in mind that once you’ve selected a banking option as your deposit method you’ll also need to use it to withdraw money from your account. This is because gambling sites require you to use the same deposit and withdrawal method.
Why casinos offer a first deposit bonus up to 100%
Casinos offer a first deposit bonus of up to 100% for the simple reason that they want to attract new players to their sites.
The gambling industry is incredibly competitive because many casinos offer lots of the same games, have similar looking websites and can provide a near indistinguishable experience.
Bonuses are a way of standing out against the competition by providing a hook to prospective players. Offering a first deposit bonus of up to 100% might be the difference between an online casino gaining a new gambler or losing them to a rival.
With this in mind, it makes complete sense for casinos to offer a 100% deposit bonus.
Is a 100 first deposit bonus worth it?
Whether a first deposit bonus is worth it or not is really up to what you want from your gambling experience and what you’re prepared to do to achieve this.
If you want to play lots of casino games and you’re willing to deposit some extra money to boost your cash reserves then a 100 first deposit might be worth it for you.
If you want to play lots of casino games but you aren’t willing to deposit some extra money to boost your cash reserves then a 100 first deposit bonus probably isn’t worth it for you.
The key thing to remember is that you should always gamble responsibly. Even if you like the idea of getting some extra cash, casino credit or free spins, never sign up for a bonus if it requires you to deposit more money than you’re comfortable with.
Can I withdraw from a 100 first deposit bonus?
You can withdraw the winnings you make from using a 100 first deposit bonus. To be able to do this you must meet the terms and conditions of the specific offer you’ve signed up to.
You can find the T&Cs of a 100 first deposit bonus advertised clearly with the offer, as gambling sites are legally required to do this.
These are some of the things you might find in a bonus’ T&Cs:
Restrictions that say you can deposit 20 max bonus pounds only
Notes saying only bonus funds can be used on certain games
Limitations on what your bonus funds count towards
We recommend that you read the T&Cs before signing up for an offer, so you know exactly what you need to do to withdraw your bonus winnings.
Where can I get a 100% first deposit bonus?
You can get a 100% first deposit bonus from the UK’s finest online casinos. Many sites will include their welcome bonus offers on their homepage, often with a carousel banner advert that clearly states how much you could earn.
However, if a site doesn’t display its welcome bonus offers on its homepage then you can see what it has available by heading to its promotions page.
