What are casino bonuses?

Casino bonuses are exactly what they sound like — bonuses offered to both new and existing players, enticing you to place bets, try out games, and play more often. 

While casino bonuses are offered to both new and existing players, many of the most generous bonuses are welcome bonuses, which are only offered to players opening up a new user account. Online casino welcome bonuses include deposit bonuses and no deposit bonuses. 

Other casino bonuses include ongoing online casino promotions for loyal players, VIP rewards club bonuses, and other casino offers, such as free spins and push notification offers.

Read on to discover which online casino promotions will help you win the most money — as well as stipulations, including wagering requirements, terms and conditions, and qualifying games.

Online Casino Welcome Bonuses

Online casino welcome bonuses are some of the most generous bonuses you’ll find at casinos! 

With these bonuses, online casinos hope to draw in new users who will become loyal players. Since there are so many real money casinos popping up these days (all of which offer welcome bonuses), competitors need to offer the best online casino welcome bonuses to sway new players to their platforms. 

Just a few of the most popular welcome bonuses at casinos include deposit bonuses, no deposit bonuses, and free spins and plays. Find out which types of welcome bonuses offer the best returns — and which ones you should ignore!

Deposit Bonuses

Casino deposit bonuses are some of the most generous you’ll find. While ongoing promos are designed to keep loyal players happy, welcome bonuses — particularly deposit bonuses — are designed to attract new players who are ready to make an online casino deposit!

Deposit bonuses (also called deposit match bonuses) are when a casino offers to match your deposit amount. If you deposit $100 into your online casino account, the casino will add another $100 to your account.

It’s important to note that deposit casino bonuses aren’t “real money” that you can withdraw immediately. It’s money for you to use on online casino games! That means you’ll need to wager that money before you’ll be allowed to cash it out. 

This is called a wagering requirement, and we’ll cover this topic in “terms and conditions” later.

Online casinos also won’t give you unlimited “free” funds. Most cap off the deposit match at a predetermined amount.

No Deposit Bonuses

No deposit bonuses are a great way to try out new online casinos and online casino games. 

You don’t need to deposit any of your own money to claim a no deposit bonus. Just follow the OddsSeeker link and use the bonus code (when applicable) and accept the bonus deal during the account signup process. It’s that easy!

Your funds will be available in your account within a few minutes after signing up. 

No deposit bonuses are usually less generous than deposit match bonuses. That’s because you won’t need to deposit any of your own money to claim one! Yet, these bonuses are a great way to try out an online casino without depositing any of your own money.

Free Spins, Plays & Bets

Another type of no deposit bonus is free spins. 

Free spins are popular at online casinos because one of the most popular types of online casino games is slot machines! 

Instead of getting a dollar value to bet on any game, free spins are only valid on slot machines. You’ll get a numerical value of free spins (20, 25, and 50 free spins are popular no deposit welcome bonuses). 

Some online casinos market free no deposit bonuses as free plays and free bets. Free plays and free bets could be used on certain games or to place bets at sportsbooks. 

Free spins and plays are also commonly offered in deposit bonus packages. If you deposit a certain amount, you may be able to get that deposit match — plus free spins or plays in addition to your bonus match.

This type of bonus is also popularly offered to existing players as an ongoing promo or login bonus. 

You may only be able to use free spins or free bets on certain slot machines or games, so make sure you’re interested in those games before accepting such bonuses. 

Best Online Casino Promos - Ongoing Promotions

If already have an account at your preferred online casino, you can’t take advantage of these welcome bonuses, as they are only for new users! 

Yet, we also happen to review the best online casino promos for current players, too. Also known as ongoing online casino promotions, these deals are for loyal players who want to take advantage of ways to earn bonuses — just by logging onto their accounts or playing qualifying games.

The easiest ways to get ongoing promos are to enable push notifications on your casino app, join a VIP Program, or invite friends and family to play. 

VIP Program Casino Offers 

Most online casinos offer promotions to VIP and rewards club members — as well as big spenders!

When you sign up for an online casino account, most platforms will also automatically enroll you in the VIP rewards club (if applicable). 

For every bet you make online, you’ll collect points to spend on prizes, such as merchandise, free plays, or hotel stays. The more you play, the higher you’ll climb within the rewards club tier levels. 

Keep playing to keep your current status (or climb to higher tiers to earn bigger rewards). 

Mobile Casino Bonuses

When you download the online casino app, you’ll be eligible for mobile casino bonuses. 

Most online casinos send offers via push notification, email, or text. When you sign up for notifications, you’ll be notified when the online casino is running a special deal, such as a login bonus or other ongoing promo. 

Casino apps often offer a better user experience than the mobile browser version. When you download the casino’s app, you’ll be able to customize your home screen experience, place bets with the touch of a button, and deposit and withdraw funds from your casino account.

By enabling push notifications, you’ll be notified when the online casino is offering a special promo — instantly. These offers happen fast, so enabling push notifications is the easiest way to stay on top of an online casino’s offers.

Online Casino Bonus Terms and Conditions 

As the saying goes, “You can’t get something for nothing.” And that saying rings true for online casinos.

With every online casino signup bonus, you’ll find (at least) a few restrictions, otherwise known as terms and conditions. These terms and conditions dictate the rules that guide how you may use bonus funds and the steps you must take before cashing out winnings made with these funds. 

Just a few terms and conditions of signup bonuses may include minimum qualifying deposits, payment and withdrawal terms, and wagering requirements. 

Be sure to read the terms and conditions of each promo thoroughly, so you’re not disappointed when it comes time to cash out your winnings.

Minimum/Maximum Qualifying Deposits

Real money online casinos often dictate the minimum qualifying deposit for welcome bonuses — though not all do. All online casinos dictate the maximum amount of money you can deposit for a deposit match bonus.

A minimum qualifying deposit is the minimum amount you can deposit into your online casino account to qualify for bonus funds. Usually, this is around $10. 

The maximum qualifying deposit is the maximum amount an online casino will match for a deposit match bonus. You may deposit more than this amount into your account, but the casino will only match up to a certain amount.

Wagering Requirements 

Wagering requirements (also called playthrough requirements) are set limits of the number of times you’ll need to play with bonus funds before you can cash out your winnings. 

Because online casinos aren’t just giving out “free money” to be withdrawn from your online casino account, you’ll need to play with your bonus funds before you can withdraw them! And not all online casinos allow you to play with those bonus funds just one time, either.

Most online casinos require you to play with your bonus funds up to 20 or even more times before you can withdraw those winnings. Some online casinos only require you to play the funds once or twice before withdrawing winnings, but those deals are often accompanied by caveats, too. 

You’ll also need to pay attention to time and game restrictions, as well as qualifying games, too. 

Qualifying Games 

Not all games are considered equal when it comes to signup bonuses. 

You can only use bonus funds on qualifying games — and you can only use some games to play toward your wagering requirements.

Online casinos set different games at a percentage of wagering requirements. For example, slot machines may count 100% toward wagering requirements, table games may count 80% toward wagering requirements, and video poker may count only 10% toward wagering requirements. 

For example, if you got a $100 bonus with a playthrough requirement of 1X and you were playing $1 per game on a game that only contributed 10% toward wagering requirements, you’d need to play that game 1,000 times to meet the requirement. 

Some games at online casinos don’t count at all toward wagering requirements, so read the terms and conditions carefully before accepting welcome bonuses. 

Game Restrictions 

Just as there are some games that only satisfy a percentage of wagering requirements, there are some games that are not eligible to satisfy these requirements at all — or that you can use bonus funds to play.

If you’re signing up for an online casino and accepting a welcome bonus only to play one specific game, you may want to read the terms and conditions of the deal very carefully. You don’t want to deposit money into your account, only to find out that your favorite game isn’t eligible to play using welcome bonus funds.

Bonus Time Limits

You only have a set amount of time to use your welcome bonus funds. Most real money online casinos set a date (usually 30 days or so) by which you must use bonus funds before they are raked back from your account.

Winnings Caps

Online casinos won’t offer welcome bonuses if they don’t make any money off them. It’s important to remember that an online casino’s goal is to make money from players — not to give it away.

You can only win up to a certain amount when playing with a welcome bonus, so be sure to read the terms and conditions of promos if you’re worried about these caps.

How to Choose the Best Online Casino Sign-Up Bonus - 300

Frequently Asked Questions

Have a few more burning questions about the best online casino signup bonuses? Check out our FAQs to find out more!

What are casino signup bonuses?

Casino signup bonuses include both first deposit and no deposit bonuses that you can use to try out an online casino’s platform. These bonuses are usually only valid for new players, who haven’t previously signed up for an account with the online casino. Also known as welcome bonuses, they’re a great way to see if you want to try out games. 

What online casino has the best signup bonus?

That depends! We happen to love several online casino signup bonuses (and we wouldn’t try to pigeonhole you into favoriting one casino over the other). 

The best signup bonuses offer a generous amount of account funds to try out the platform, as well as low wagering requirements. We also look for online casinos that offer a great user experience and a solid selection of games.

What are free spins?

Free spins (similar to free plays and free bets) are exactly what they sound like — free spins you can use on select online slot machines.

Use these free spins to play select online slot machine games and potentially win even more funds to play (or money you can cash out once you satisfy wagering requirements).  

How do online casino deposit bonuses work?

Online casino deposit bonuses work differently on each platform. Yet, most online casinos offer to match your deposit amount (up to a certain threshold). 

You must satisfy wagering requirements before you can cash out your winnings and play certain, qualifying games with your promo funds.  

Can you win real money with casino bonuses?

Yes! You can absolutely win real money with casino bonuses. The only caveat is that you must satisfy the wagering requirements and follow the terms and conditions to cash out bonus funds.

This means you’ll need to play the casino bonuses a certain number of times before you can cash out those funds — casinos wouldn’t just give you “real” money without requiring you to play with it first.

Are online casinos with signup bonuses legit?

Most online casino signup bonuses are legit — though there probably are some not-so-legit ones out there too.

If you’re worried about the legitimacy of online casino bonuses, we recommend only accepting bonuses at licensed and verified casinos. Don’t know which ones are legit? We recommend only signing up for accounts at casinos recommended by an online casino review site, such as OddsSeeker!

What other casino offers are there?

Casinos generally offer two types of welcome bonuses: deposit and no deposit bonuses. 

Deposit bonuses, also known as deposit-match bonuses, are casino funds you can snag for making a deposit into your account. The casino will usually match your deposit up to a certain dollar amount. 

No deposit bonuses include free account funds (usually around $10 or $20), free spins, and free bets. You don’t need to make a deposit to get this type of deposit, though you’ll still need to satisfy wagering requirements to cash out winnings made with bonus funds.

How do casino sign-on bonuses work?

Simply use the OddsSeeker link to get to the casino sign-on bonus deal. Use the bonus code (where applicable) and accept the deal. 

Make a qualifying deposit (if it’s a deposit match), and accept the terms and conditions. You should receive your bonus funds within 30 minutes or so. Play with your bonus funds and cash out your winnings (once you’ve satisfied wagering requirements). 

Can I use a sign-up bonus for online casinos on any game?

Nope, not any game! Casino signup bonuses are only good to use on certain games at online casinos. 

Most real money casinos allow you to use bonus funds on slot machines, poker, roulette, baccarat, and video poker. Check the terms and conditions of each deal to find out which games you can play with bonus funds. 

Do online casino welcome bonuses expire?

Yes! Most casino welcome bonuses expire within 30 days of accepting the bonus. 

You only have a limited amount of time to use your funds. Bonus expiration dates are always noted in the terms and conditions. 

Are online casino promotions only for new players?

Welcome bonuses are only valid for new players. You must set up a new user account to accept such a deal. Yet, many online casinos offer ongoing promos to keep loyal players happy, too!

Most of the deals we review on OddsSeeker are only for new players, yet we also try to let you know about ongoing promos whenever possible, too.

Can you win real money with no deposit bonuses?

Yes, it’s possible to win real money with no deposit bonuses. Again, just pay attention to the terms and conditions of each deal before accepting one to see if the deal is worth it or not.
