Also known as ‘Welcome Bonuses,’ they usually comprise a percentage match of the initial deposit made by a new player.
This often amounts to at least 100%, although many operators push the envelope by offering up to 200%. Extras such as bonus spins are often included in the best casino deposit bonuses as well.
However, such incentives have become so widespread in the gambling industry that it can be difficult to identify the ones which offer the best ‘value’.
To help you in this task, WDW Bingo has compiled a list of the most competitive welcome deposits currently available.
We’ve also included advice about some of the things to keep in mind when searching for the best casino welcome bonuses, such as wagering, cash-out rules and time-limits. Scroll down to find out more.

Best Slot Bonus Offers UK
So what constitutes the best slot bonus? Well, this is a subjective question – some players look for percentage matches while others prefer the additional perks such as bonus spins. Whichever your preference, there are a few things to keep in mind when searching for competitive welcome bonuses.
What is a good Casino Deposit Bonus?
As a general rule of thumb, look for welcome bonuses that offer at least a 100% match of up to £200. Anything lower should probably be avoided unless the promotions include additional incentives that are unusually generous, such as extra spins or no wagering slots.
Usually, you’ll need to deposit £10 to get bonus slots. You will also find some more generous slot offers than 100% match. For example, at some sites you’ll see deals like deposit £10, get £30 slots or even more!
Our largest bonus in 2025 comes from Fafabet – look at the size of that thing!
What other types of casino bonus exist?
Extra Spins
Most online casinos offer from 50 to 120 extra spins as part of their casino deposit bonuses. There are exceptions of course, with some welcome promotions comprising up to 200. However, such offers are somewhat thin on the ground so try to identify bonuses that include a minimum of 50 spins.
What about wagering requirements on a slots bonus?
Behind every welcome offer lurks the bête noire of every casino-gamer: wagering requirements. Like it or not wagering, or play-through rules as they’re sometimes known in gambling parlance, are a fact of life. They generally require players to wager a multiple of their deposit (as well as the bonus itself in some cases), before any winnings can be withdrawn.
For certain players, wagering doesn’t present much of a problem. However, they should be treated like a wounded tiger – with respect and caution.
In the early days, operators would hide these harsh stipulations in their T&Cs pages. But recent, regulatory changes now require them to be included in all promotional advertising. Take a look at any casino welcome offer and you’ll see wagering rules written in small print beneath the shrieking promo headlines.
It’s quite difficult to recommend an acceptable wagering rate. Other than zero, we’d suggest something in the region of 30 – 40. However, you might want to stretch higher, depending on the generosity of the related bonus. For more information, see our no wagering slots page.
Time-Limits
Because of wagering rules, you’ll also need to pay close attention to promotional time-limits. After all, playing through a bonus and/or deposit some forty-or-so times won’t happen overnight.
So to protect any winnings you might accrue, be mindful of how long you’ve got to satisfy this requirement. The terms of many promos and offers can be satisfied within 30 days but be aware: some operators still impose draconian time-limits which make it extremely difficult to meet wagering rules in time.
Game Weighting on the Best Slot Bonuses
Game weighting should also be considered when choosing the best casino deposit bonus, with online casino games contributing different percentages towards the completion of wagering requirements.
While many standard slots contribute 100% to play-through rules, there are some, particularly those with high RTPs, which offer less. Additionally, table games are usually assigned low weighting percentages because their house edge is that much lower than other games.
To conclude then, it’s always a good idea to read the terms and conditions thoroughly before committing to any casino or slots deposit bonus. Although some welcome packages aren’t quite what they seem, there are plenty of offers, such as the ones included above, which offer genuine value for money. Just be sure that you’re fully clued-up about each restriction in place.

Yes, very often a slots site will stipulate which slots and games are eligible in the bonus. Be careful to read the terms and conditions! Some bonuses may only be eligible on one slot game. Some may be eligible across a certain platform of slots. Some bonuses will accept a great majority of slots bonus across the site, but this is incredibly rare.
Sometimes, but this is becoming increasingly rare. Check the terms and conditions, but most casino bonuses will ask you to play through your bonus first.
Yes – this is pretty much always the case. The generosity of this figure varies massively from £2-£3 all the way up to hundreds of pounds. Often, it depends on the type of bonus. Free Spins winnings often have a lower cap. This information will always be included in the terms and conditions.
Yes, frequently. Check the T&Cs to see what the maximum bet you can make with your bonus is each time.
Usually, a site will have a separate live dealer casino welcome bonus. The new player may even be offered a choice between different types of welcome bonus. However, it is rare for a standard casino welcome offer to be playable on live dealer casino games. Sometimes they may be eligible, but the game weighting towards the wagering requirement may be miniscule.
