Slot Deposit Bonus Deals 2024

The Best Deposit and Welcome Deals for Online Slots in 2024

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.

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 2024 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 This is important, some bonuses can be used to play over and over again, though never withdrawn.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

Online Slots BonusesChecking 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!
