The Best Deposit and Welcome Deals for Online Slots in 2021
As an online slots player, you’ll see a big choice of bonus deals from online casinos. This page goes beneath the headlines, showing that not all slot welcome bonuses are created equal.
Free spins are one of the best casino bonuses for slots enthusiasts, especially those who enjoy getting to play with no strings attached. That's because free spins actually offer you the chance to spin the reels. Like in old times the best way to increase your understanding of what is going on in gambling sphere, is to learn all about new slot games which you can try at top casino 2021 for UK in the nearest time. The following list will contain the most well-paid, nice and impressive slot machines of 2021, which have the highest RTP (Return to player).
Many slots casinos offer free spins as an incentive to get players on their books – this type of completely free bonus deal is covered elsewhere here at Sit N Go Planet. This page focuses on how you can take maximum advantage of those bonuses which are tied to deposits.
Here is what you’ll find below:
First up, my top 3 deposit bonuses for 2021 can be found in the table below. These are split between US and non-US players.
Next you’ll find information on how to compare slot deposit offers, and make sure there are no nasties lurking in the small print.
After that something even more important than the welcome bonus is covered, including my ‘Golden Rule’ before signing up.
Finally, if you are looking for a certain type of slot software, then you’ll need to know where to look for the best deposit bonus that has your preferred games, you can find exactly this information at the bottom of the page.
How to Read Welcome Bonus Deals at Slot Casinos
This section covers how to compare bonuses side-by-side. You’ll see a lot of ‘big headlines’ at online casinos – 100% to $1000! 200% to $350 or 100% to €2500 for example. These bonuses can all work differently, and some of them will be much better than others when it comes to getting the money into your account.
3 Initial Factors to Consider
Is this welcome bonus in one lump, or can it be split over several deposits (if you hit a bad run first time through, this can be a very useful way of saving the day).
What is the play-through requirement? This can be calculated in terms of deposit amount only, or bonus + deposit amount and can range from 20x (combined) and up. This is the total amount you need to wager before the bonus is yours to keep.
Is the bonus cashable, or is it for play purposes only? This is important, some bonuses can be used to play over and over again, though never withdrawn. These often come with a rule that they are removed when you do withdraw any winnings. Obviously this is nowhere near as good as a slot welcome bonus which is fully cashable after meeting the play-through criteria.
These are not the only factors which I consider before taking the plunge. In addition, the casino has to have a proven track record of fast payouts and no major scandals / issues – and there need to be no ‘nasties’ lurking in the small print.
You should look out for casinos which have certain slots excluded from the deposit bonus deal. You might also find ‘banned’ games for the duration of your bonus – roulette is a common example. Even a single spin could invalidate your bonus, and you’ll only find out about it when you come to withdraw any winnings. Reputable casinos rarely have this, though the newer / smaller and outfit the closer you should look for this kind of thing.
On the positive side, many slot deposit bonuses come with extras. These include the much maligned free spins (often many more than you’ll get for no-deposit offers). Look out for caps on winnings and exclusions for jackpots with these, if for no other reason as to not have a ‘false alarm’ if you thought you won $1 million+ only to find it excluded from the free spins offer!
Some casinos offer slot tournament entries with your deposit bonus. These are games of chance, you’ll have a timed session on a slot to make as much as possible to beat the other players to a leader board prize.
Planet Mark’s Golden Rule
I have mentioned this elsewhere, though for slots fans it is very important. Here it is:
Welcome bonuses will be gone in 30 to 60 days. If you find a casino you like and trust, then it is the ongoing rewards, promotions and loyalty scheme which has by far the biggest effect on your bankroll… so, check this before you join!
Ongoing Rewards Checklist
Checking ongoing rewards is easy enough, no reputable casino will hide details of their loyalty points scheme. Look for tiered ones, where you’ll earn more points after betting a certain amount. It only takes one win and some increased stakes and you could easily find yourself moving up several levels at once. Some casinos have VIP level loyalty schemes for high rollers, you’ll be invited to these by reps if you bet big enough – if you have an eye on the bigger limits, it can pay to make sure that VIP schemes are available before you get started.
Other rewards include regular tournament entries, free spins on new games and one-off promotions (for example double points for trying out a new game). You can also look for extra free chips for checking out the phone version of a casino, and reload bonuses in case you do bust out early.
The best casinos (and I count Bovada (for the US) and Unibet (for non-US players) here) have a lot of one-off and special promotions to keep their loyal players entertained – and their bankrolls boosted.
Rogue Casinos Alert!
When not to deposit no matter how good a bonus looks!
There are certain ‘red flags’ which mean you should decline a deposit bonus no matter how great a deal appears. My rule of thumb is to stick with known casinos, which have been in business for a few years at least. This is plenty enough time for any shady practices to come out into the open.
I look out for 3 things.
First, a license – and a link to that license on the website of the issuing authority (not just a badge that says ‘we are licensed’). For US casinos licenses for offshore casinos are issues by Antigua, Netherlands Antilles, Panama, Kahnawake and others. For non-US casinos, Malta, Gibraltar, Alderney and the Isle of Man are the main reputable authorities.
Second, you’ll need to see external testing of game fairness (again, a link to the testing site, for example TST or iGaming Labs is ideal). This means the deal and reported RTP percentages have been externally verified.
Finally, a quick search online can save your money if you see a lot of posts / issues regarding bonuses being forfeited or payments withheld. You’ll often find players crying about their losses, this is normal enough – you are looking for genuine scandals.
By choosing a casino with many years of experience and a good reputation before you make your deposit and claim your slots welcome bonus, you should have no problems at all!
Slot Welcome Bonuses for Specific Slots Software
Best Slot Offers Online
If you already know what kind of slots software you prefer, and are looking for options for a slot deposit bonus that features your choice, then this is the section for you. Some of the big casinos offer slots from many different software houses – which certainly makes life easier.
US Slot Software Welcome Offers
The 3 biggest brands are RealTime Gaming (home of the reel series games), Rival Gaming (iSlots) and BetSoft (amazing 3D slots). One casino that has them all, as well as a giant sized multi-deposit welcome bonus is Bovada.lv. This is an old and trusted brand (it is part of the Bodog family) which is famous for its top quality promotions – check out www.bovada.lv for the latest.
If you are looking for the smaller Arrows Edge slots then I recommend Drake Casino instead, a top-rated brand which also features BetSoft Games. WGS (Vegas Technology) slots can be enjoyed at the established www.betonline.ag.
Non-US Slot Software Welcome Offers
There are many software houses which cover international casinos – you can get an insight into which ones over at my Online Slot Software page. Here is where to find the main ones.
PlayTech (famous for the Marvel range of jackpot slots) can be enjoyed at one of the oldest and classiest casinos around – Europa Casino. If you are from the UK then you will not be able to play at Europa, the sister site Titan Bet Casino has a UK license and all the PlayTech Slots.
MicroGaming (Mega Moolah, Thunderstruck II and more) fans really can’t go wrong with 32Red Casino. Cleos vip room. Again this has a UK license, and also a unique 160% slots deposit bonus which is very fast to clear.
If you are looking for IGT, WMS and NetEnt slots – I strongly recommend Unibet. This huge brand has more than 660 games (and counting) from all of the major software houses, including some up and coming brands on the cutting edge of slot design. Check out www.unibet.com for the impressive list.

How to Choose the Best Slot Bonus
When choosing looking for the best slot bonus to play with, there are a number of thing you should look out.
- No Deposit Bonus
- First Deposit Bonus
- Wagering Requirements
A term you’ll come across with virtually all casino welcome bonuses is ‘wagering requirement’. This is something you definitely need to understand if you want to be able to withdraw your bonuses, and it will help you to make the best choose in terms of which offer you want to choose.
A ‘wagering requirement’ is simply how many times you have to bet the bonus amount you have been given before you can withdraw it.
For example, if a sign up offer on a particular casino is ‘100% First Deposit Bonus up to £100’, if you deposit £100 you get an additional £100 in bonuses. Although you will most likely be able to play with this bonus immediately, in most cases you won’t be able to withdraw it before you meet the ‘wagering requirements’.
Wagering requirements typically range from 4x-50x the actual amount of the bonus. If the wagering requirement was 10x, then you would have to wager £1000 in order to be able to withdraw your bonus money. Now, it is possible that could do this just repeatedly using your bonus money, but there is a good chance you will have to use the money you actually deposited and possibly money from further deposits. This is certainly likely to be the case when wagering requirements are higher.
Therefore, you shouldn’t simply be attracted to the biggest looking bonus, because if it has a 40x wagering requirement to claim, there is a good chance you might not want to wager that much.
