Online Slots Bonuses And Promotions

Without a doubt, real-money online slots are the most popular form of online gambling today. And that makes a lot of sense, given that brick-and-mortar slots have been the most popular form of in-person gambling since they first hit the scene back in 1894. But online slots are so much more popular than other games for another reason, too: online slots bonuses.

All the top online casinos we recommend offer casino bonuses that focus on slots first and foremost, giving players huge boosts to their bankrolls just for joining. Most sites also offer slots bonuses to returning players making fresh deposits. Of course, before you accept any online slots promotion, it’s important to understand exactly what they are and how they work.

Current Online Slots Promotions – Best Online Slots Bonus Codes For 2024

All the best USA online slots sites have multiple casino bonuses to help you win as much real money as possible. Most of these promotions are for all-inclusive casino action, but some are slots specific. A few sites even have special slots bonuses for individual games, such as “Game of the Week” bonuses and promos for brand new slots titles.

Regardless, you can expect the standard bonuses listed below to be offered year-round for new and returning players. Of course, we strongly recommend checking with your online casino of choice to see what current bonuses are available every time you make a fresh deposit.

Pro-Tip: The above bonuses are for non-crypto deposit types. If you want to get the biggest possible online slot machine bonuses, you’ll need to deposit with Bitcoin or another supported cryptocurrency. Most of the top sites give players 2X-3X more free spins when depositing with crypto compared to more traditional banking options (i.e. credit, debit, bank wire, etc.)

Where To Get Online Slots Bonus Codes

In years past, you could find the best online slots promo codes by scouring the Internet and looking for new online slot casino reviews, obscure gambling articles, various enthusiast forums, and so on.

And while that’s still done to a small degree – we occasionally get special promos for our readers that offer bigger deposit matches than standard bonuses – most sites now have all their up-to-date promo codes right in their “Promotions” sections.

Some sites even require no bonus codes at all. You just need to click or tap the appropriate toggle when making your deposit, and the bonus is applied automatically!

How To Use Online Slots Bonus Codes

If you’ve never used an online slots bonus before, the process is straightforward. The first step, of course, is to pick a reputable real-money slots site, sign up, and make a deposit. It’s during this depositing process that you’ll enter any bonus codes or opt into a bonus using a provided toggle.

  1. Navigate to any legit cash slots site we recommend by following the links on this page.
  2. Click or tap the SIGN UP or JOIN button and enter in all necessary information as directed. Be sure to use only your real name, email address, phone number, etc. Warning: These legit casinos will never ask for sensitive info like your SSN, mother’s maiden name, etc. However, you will be required to submit identity verification during your first payout - it is conceivable they may ask for your social at that point. 
  3. Choose a deposit method. We recommend Bitcoin or another supported crypto coin because these come with the biggest and best slots bonuses. However, all deposit methods have valuable promos attached.
  4. Choose your bonus. Because bonuses have playthrough requirements, please be sure to understand what these entail. All the best sites have easy-to-meet bonus wagering terms, making them appropriate for the vast majority of players. Note: Playthrough is explained further down this page.
  5. Submit your deposit.

As you play, it’s important to understand how bonus free plays work. When you place a wager on a slots game or any other casino table game, you’ll have the option to make that bet with your cash balance (the actual cash or crypto you deposited) or your bonus balance (the money your site added to your account when you accepted the current promotion).

These balances are kept separate so that, should you choose to abandon a bonus (perhaps a better bonus is available or the current bonus terms don’t work for your play style), you’ll only forfeit any money won using the bonus free play balance. This way, all bets won using your cash balance remain in your account. As such, bonuses are 100% risk free.

How To Claim Online Slots Bonus Payouts

Once it’s time to get paid, the actual withdrawal process is simple: Just go to your site’s cashier page, choose the withdrawal option you prefer (again, crypto is the best, fastest, and least expensive online casino payout method), and follow the on-screen instructions.

However, when you’re claiming a gambling payout that includes bonus winnings, you will only be able to do so once you’ve met your active promotion’s terms and conditions.

If you choose to receive your payout before you’ve completed the terms of the bonus, you’ll forfeit any money earned via the bonus and will only be able to claim winnings associated with your standard deposit-based bets.

How To Get The Best Online Slots Bonuses

For the best slots bonuses online, it’s really no more complicated than this: Make your deposits using cryptocurrency. As a rule, crypto gambling deposits come with much bigger match percentages and total bonus amounts.

For example, if you deposit at Bovada with Visa or Mastercard and get the maximum bonus, you’d score $3000 for a $3000 deposit (100% match rate) and have $6000 to play with. However, if you use Bitcoin or another supported crypto instead, you’d be able to get $3750 for that same $3000 deposit (125% match rate).

In most cases, standard slots bonuses and enhanced crypto slots bonuses have the same – or very nearly the same – playthrough/rollover requirements, making their terms no more difficult to meet than those for regular promotions.

Slots Bonus Playthrough Requirements

The only thing you really need to think about before accepting an online gambling bonus – that is, the only “fine print” that really matters when it comes to your gambling bankroll management – is the bonus playthrough amount.

Playthrough – also called rollover – is the wagering requirement attached the bonus in question. Casinos include these so they’re not bankrupted by giving out free money all the time. Essentially, playthrough requirements simply ensure that players don’t just sign up, get some free cash right off the hop, and bounce.

Fortunately, no matter which site you join, legitimate slots sites all have roughly the same bonus rules:

  • All bonuses come with playthrough requirements associated with the full deposit + bonus amount
  • Playthrough rates (25X, 35X, 45X, etc.) represent the amount of money you must wager before withdrawing any funds associated with the bonus
  • Playthrough accumulates whether you win or lose a given wager
  • Different games have different bonus contribution rates (see your site’s bonus contribution chart for more information).

Note: At some sites, you might not earn playthrough credits when playing progressive online slots. Other sites may allow progressives to accrue playthrough, but at a lower rate than standard slots games.

Bonus Online Slots Vs. Free Online Slots

Online slots are popular, but many gamblers – or, rather, potential gamblers, search for “free slots with bonus rounds,” “free slot games with bonus payouts,” and similar.

Naturally, some of these players will get what they’re after, but others are going to conflate terms and come away confused. To prevent that, we want to clarify the differences between the two quickly.

In the online gambling industry, “bonus online slots” are those slots rounds played with bonus winnings or earned as special prizes from previous spins. Bonus online slots allow you to win actual money.

On the other hand, “free online slots” are basically just video games gussied up to look like real slot machines. You can play as much as you want, but you can’t actually win any money.

Free online slots might constitute the “Practice” or “Demo” modes available at many legit real-money online casinos. The term might also apply to iPhone slots apps and Android slots apps – with the exception that such mobile slots apps actually end up costing money to play without ever paying out any actual winnings.
