What is a Casino Welcome Bonus?
A casino welcome bonus is a type of casino bonus specifically offered to new players as an incentive to sign up and deposit money at an online casino site. Casinos need to beat the competition when it comes to getting the attention of prospective new customers, which is why a casino welcome bonus is often among the most generous and lucrative real money rewards available.
Most UK online casinos have a welcome bonus, and while they vary between sites, they most commonly involve a deposit match and/or free spins offer. More importantly, they give you the chance to try out top casino sites with bonus cash from the outset.

Types of Casino Welcome Bonus UK
While they’re all targeted at new players, an online casino welcome bonus can come in many different types. Here are some of the most common you’ll come across at gambling sites with a welcome bonus:
Welcome Bonus Deposit Match
A deposit match gives you bonus funds to play with on top of your first deposit, up to a specified amount or percentage. For instance, if you deposit £50 while claiming a 100% deposit match welcome bonus, the casino will add an additional £50 to your account, giving you £100 in total to play with.
Welcome Bonus Free Spins
With a free spins welcome bonus, you’re given a set number of free spins to use on slot games after you’ve created your account or made your first deposit. These are normally made available on the most popular slot title(s) at the casino.
Welcome Bonus Cashback
Cashback returns a percentage of your losses during a specified timeframe up to a certain amount. For instance, Yeti Casino gives new players up to £111 in cashback across your first 30 days. By claiming cashback welcome bonuses, you can make your initial bankroll last longer when you first sign up.
Welcome Bonus No Deposit
Certain casinos don’t require you to make a deposit to claim the welcome offer, meaning you can effectively get a free welcome bonus. A casino welcome bonus with no deposit can involve bonus funds or free spins, but often comes with more restrictive wagering requirements.
Welcome Bonus Codes
In some instances, you’ll need to enter a bonus code on top of creating an account and making a deposit to activate the welcome bonus. You’ll normally be prompted to do this during the sign-up process or on the deposit page.
Slots Welcome Bonus
Some slot sites with welcome bonuses have rewards that you can exclusively use on online slot games. This may involve free spins or bonus funds that are only eligible for slots wagers. This can be a good way to try out the latest or most played slots at a casino.
Live Casino Welcome Bonus
A dedicated live casino welcome bonus gives you free money to use on live dealer games, meaning you can join the immersive fun with a boosted bankroll. Live casino bonuses tend to involve larger rewards, as the games often have higher minimum bet limits.
Bingo Welcome Bonus
More casinos are starting to offer welcome bonuses tailored for bingo games and players. These give you bonus funds you can use when playing online bingo in both RNG and live formats.

Popular Casino Welcome Bonus Games
Online sites with a welcome bonus allow you to use them on a variety of games. The most popular include the following:
Slots
Online slots are the most common type of game you can get welcome bonuses for, as you can play them with both bonus funds and free spins. Welcome bonuses are normally offered for popular slots at the casino, while the slots themselves often contribute 100% towards wagering requirements.
Table Games
You can use welcome bonuses to play classic RNG table games, including roulette, blackjack and baccarat. Deposit matches and cashback can give you more chances to win when trying to beat the dealer or guessing which number the roulette ball will land on. However, table games also tend to contribute less than 100% towards wagering requirements.
Live Casino Games
Live dealer games are often not eligible for welcome bonuses as they have higher minimum bet limits, but the good news is that some casinos do offer specific live casino welcome offers to cater to live dealer fans. These give you bonus funds to specifically use on live games.
Bingo
Online casinos and bingo sites offer unique welcome bonuses for both RNG and live bingo games. You can receive free entries and tickets to use on bingo titles, with often have smaller rollover requirements compared to other welcome bonuses.
Casino Welcome Bonus Terms & Conditions
While at first glance welcome bonuses may seem lucrative and exciting, you should always review the accompanying T&Cs, as these can dictate how generous the bonus actually is. We suggest looking out for the following:
Wagering Requirements
The wagering requirements list how many times you need to play through your bonus cash before you can withdraw it. Generally, anything in the range of 35x or under can be rated as reasonable, while 50x or higher is strict. You’ll normally find harsher wagering requirements when claiming a free welcome bonus.
Expiry Date
Every casino welcome bonus has an expiry date attached. You need to use the bonus by this date, otherwise it will be taken off you and you’ll miss out on the chance to win real money from it. Expiry dates often fall between seven and 30 days after you activate the bonus.
Minimum Deposit Amount
Most welcome offers require you a deposit a minimum amount of money to activate the bonus, often in the range of £10 to £20. Obviously, you can deposit more money to take advantage of a larger bonus if you want.
Maximum Win Limits
A casino welcome bonus may have a maximum win limit, which means you can’t win or withdraw any more money than the amount specified by the casino. For example, if you win £70 from welcome bonus free spins but the casino specifies a max win of £50, you’ll only get to keep £50.
Payment Method Restrictions
Some casinos won’t award you with a welcome bonus if you make your initial deposit using a prohibited payment method. These most often include e-wallets and prepaid vouchers, as they make it more difficult for the casino to verify your identity and can therefore be used to exploit bonus offers.
Game Eligibility
A casino may specify which games you can use welcome bonus funds or free spins on. For instance, slots-based welcome bonuses are normally restricted to one or a small range of titles. Different games may also contribute varying amounts to any wagering requirements.
Pros and Cons of Casino Welcome Bonuses
Hopefully, we’ve exhibited the benefits of claiming and using a casino welcome bonus to you, but that doesn’t mean they’re perfect. Check out the pros and cons to be aware of in the table below:
Deposit Options to a Claim a Casino Welcome Bonus
You can use several online banking methods to fund your account when you first sign up and make a deposit to claim a casino welcome bonus. Most casinos accept a variety of payment options, from debit cards and bank transfer to mobile methods such as Apple and Google Pay.
The only thing to remember is that a casino may exclude some of its accepted deposit methods from claiming bonuses. Most commonly, it does this for e-wallets and prepaid vouchers, as using them makes it harder for the casino to verify your identity. You can check this information for a welcome bonus in the T&Cs.
