Most Popular Casino Bonus Types

There are many different types of online casino bonuses offered to players year-round. Casino players should always look for welcome bonuses before signing up for a new online casino account, and then make a habit of regularly checking a site's Promotions page for the latest casino bonus offers. Learn more about the most popular types of online casino bonuses below.

Online Casino Sign Up Bonus

An online casino sign up bonus, also known as a welcome bonus, is a promotion available to new customers. These casino bonuses can come in various forms and are often the best bonuses around. They include:

• Match Deposit Bonuses: A player's first deposit is matched up to a certain amount in bonus credits, like BetMGM Casino's "100% match up to $1,000" welcome bonus.

• Play and Get: A player receives bonus money after playing with a certain amount of their own money.

• Initial Losses Back: Net losses incurred during a player's first 24 hours of play are added back to their account as site credits up to a certain amount, like FanDuel Casino's "Play it Again up to $1,000" promotion.

Sign up bonuses tend to be the biggest online casino bonuses available. Online casinos aim to entice new customers to open a casino account with these lucrative offers.

No Deposit Casino Bonus

While most online gambling promotions require a deposit to be claimed, no deposit bonuses award bonus credits with no deposit required. These promotions are very rare in the online gambling industry, and are generally only offered on special occasions like when a new online casino market is opening up in the United States.

• Example: There are no active no deposit bonuses on the market right now, but sites like BetMGM, Caesars Palace, and DraftKings are offering extra bonus money on top of their deposit bonus matches as welcome bonuses, which are not dependent on the amount you deposit.

Recurring Casino Bonuses for Existing Casino Players

Recurring casino bonuses are daily or weekly promotions aimed to reward existing customers for their loyalty. These types of bonuses include promotional spins, giveaways, and opportunities to earn loyalty program points at double or triple the usual rate.

• Example: BetMGM Casino's "Arcade Power-up" promo, in which players who play online slots or other casino games earn a daily bonus worth up to $5,000.

High Roller Casino Bonuses

High Roller casino bonuses are promotions catered towards players with larger bankrolls. Most real money online casinos have VIP programs that award players different perks based on their level of play, with high rollers who reach the highest tiers earning exclusive bonus codes, gifts, and rewards.

• Example: High Rollers that reach the Diamond or Onyx tier levels at DraftKings Casino receive exclusive perks like gift packages, live event access, and VIP hosts.

Free Spins Casino Bonuses

Free spins casino bonuses award players a certain number of free spins on selected online slot machines. Casino players may receive free spins as part of a welcome bonus or as a daily or weekly promotional giveaway for existing customers.

• Example: bet365 Casino's "10 Days of up to 500 Free Spins" welcome offer.

Mobile Casino Bonuses

A mobile casino bonus is a bonus offer designated for players using a casino app to play on their phone or tablet. Most online casino bonuses work on both computer and mobile, but some are app-exclusive. Fanatics Casino is exclusively available as on mobile devices, so players must download the dedicated mobile app to claim bonuses at that online casino.

• Example: Fanatics Casino's Wager $10 Get $100 in Casino Credits! 

  
  

Specific Casino Game Bonuses

Some promotions are only available on specific games. Players may be required to play live casino games for certain giveaways or specific online slot machines for slot tournaments. Details on game eligibility can always be found in the casino bonus terms and conditions page.

• Example: bet365 Casino's "Spin Builder" promotion, in which you can earn 20 free spins when you play $20 or more on one of 10 eligible games and an additional 5 free spins per $10 of play on those games up to 100 free spins total.

Reload Bonuses

Reload bonuses are deposit bonuses for existing customers. These offers are not as lucrative as initial deposit bonus codes, but they do still provide additional value to players reloading their accounts.

• Example: The "Get a $10 Bonus on Your Next Deposit of $25 or More" reload promotion at Caesars Palace Online Casino.

Cashback Bonuses

A cashback bonus is a program that gives players a percentage of their net losses back. Instead of cashback bonuses, most online casinos offer loyalty program points that can be redeemed for bonus money as an alternative.

• Example: BetRivers allows its new players to CODE. 

Exclusive Bonuses

Exclusive casino bonuses are unique promotions that are only available at one online casino. Online casinos offer exclusive offers and rewards programs to encourage players to continue playing on their site after they have used their first deposit bonus.

• Example: FanDuel's "Rewards Machine", which gives players three free spins a day for their shot at up to $2,000 in bonus credits. 

How to Pick the Best Online Casino Bonus

When looking for the best online casino bonuses, there are a number of different factors to take into consideration. Use the tips in this section to find the best casino bonuses and get the most value you can out of them.

Make Sure the Casino is Licensed & Regulated

Regulated and licensed online casinos are the only gambling sites that are legal and 100% safe to play at. Avoid unregulated offshore casinos and stick to regulated sites that can guarantee fair play and legitimate online casino bonuses.

Search for Low Wagering Requirements

Wagering requirements refer to the amount of money that you need to wager before you can withdraw money earned on bonus bets. For example, if you get a $100 bonus with 10x wagering requirements, you'll need to bet $1,000 before you can withdraw. Seek out online casino bonuses with low wagering requirements that will allow you to convert bonus cash into real money as quickly as possible.

Understand the Instructions

Players may be required to follow a set of instructions to claim a casino bonus. These instructions may include entering a bonus code, meeting a minimum deposit amount, or taking action within a certain time frame. Check the casino bonus terms and conditions, which we'll cover in more detail in the next section, to make sure you understand how the bonus works and how to use it.

Look for Casino Promo Codes

Some of the best casino bonuses can only be claimed with deposit bonus codes. Look for casino promo codes like the ones listed on this page to secure exclusive welcome bonuses that may offer a higher bonus amount than the site's standard deposit bonus. 

Play Casino Games Responsibly

Online casino bonuses should always be enjoyed responsibly. Responsible gambling includes setting limits on the amount of money and time you spend playing casino games, and only gambling with money you can comfortably afford to lose. If you ever feel you are struggling with problem gambling, contact 1-800-GAMBLER by phone or visit the National Council on Problem Gambling website.

Terms & Conditions for Online Casino Bonuses

All online casino bonuses come with specific terms and conditions. Understanding the terms listed in this section will ensure you can successfully claim and take advantage of all of the casino bonuses you find online.

Minimum Deposit Amount

The minimum deposit amount is the lowest amount required to activate a deposit bonus.

• Example: The minimum deposit on a 100% Match Deposit Bonus up to $1,000 is often $20, so you will need to choose a deposit amount of $20 or more to claim this bonus.

Deposit Options

Deposit options refer to the banking methods that you can use to make a deposit. Most deposit bonuses will allow you to use any of the methods that the online casino accepts, but there may be some instances in which a bonus requires you to use a specific payment option. Banking options vary by casino and state.

• Example: Popular deposit options include bank transfer, cash at an in-person casino cage, credit card, debit card, and PayPal.

Casino Bonus Codes

Some online casino bonuses can only be claimed when you enter a bonus code. In the case of welcome bonuses, you will be prompted to enter your promo code when registering for an account or making a deposit.

• Example: To CTA at the BetMGM Casino, players can enter bonus code CODE when prompted to add their code.

Playthrough & Wagering Requirements

Wagering requirements, which are also referred to as playthrough or rollover requirements, let players know how much money they must play on casino games with their bonus cash before those funds are eligible for withdrawal. Watch out, as some wagering requirements apply to both the bonus and deposit, effectively doubling the wagering required.

• Example: A $100 casino bonus with a 1x rollover will require $100 in play before remaining funds and/or winnings can be withdrawn. A $500 casino bonus with 10x wagering requirements will require $5,000 ($500 x 10) in play.

Game Contributions

Different games contribute different amounts towards your wagering requirements. Each type of game's contributions will be displayed in the bonus's terms and conditions.

• Example: An online casino lists the game contributions for your bonus of online slots at 100%, table games at 10%, and live casino games at 0%. Every $1 you play on slots will apply $1 towards your wagering requirements, while every $1 you play on table games will apply $0.10 (10% of $1) towards them. Playing on live casino games listed at 0% would not contribute to your wagering requirements at all.

Time Limit

Players may need to use their bonus money or meet their wagering requirements before a set amount of time has passed. Typically, unused bonus funds will be forfeited when the time limit expires.

• Example: A deposit bonus awards 20 free spins on a specific online slot. These must be used and wagering requirements met within seven days of receipt, otherwise they are forfeited. 

Winning Restrictions

Some casino bonuses have restrictions on the amount that you can win. Certain casino games like progressive jackpot slots may be restricted while bonus funds are active due to these rules.

• Example: An online casino lists the maximum you can win with its 10 free spins promotion at $500. If you have a huge bonus round or a jackpot win on one of your spins, you'll only be able to withdraw $500 of the winnings.

State Limitations

Online casinos have different bonuses available in different states. Each site's Promotions page should be accurate to the state you are in, but some deals you find via search may be accessible in some states but not others.

• Example: BetRivers offers a welcome bonus of CTA in NJ, MI, and WV. But they offer a bonus of CTA in PA.

Game Limitations

Certain online casino bonuses may be limited to specific games or game types.

• Example: Players can opt-in to a "Game of the Week" bonus and earn free spins by playing that game, while playing other games would not apply to the promotion.

Tips to Calculate an Online Casino Bonus

To figure out the wagering requirements on a deposit bonus or the projected value of a free spins bonus, you will need to do some calculations. Use the tips and formulas in this section to help you with important calculations on some of the most popular types of online casino bonuses.

Deposit Free Bonus

Most no deposit bonuses come with high wagering requirements. You will need to multiply the bonus money you receive by your rollover requirement to determine how much you will need to play before you can withdraw money.

• Equation: Bonus Money Received X Wagering Requirements = Total Betting Amount

• Example: You receive a $10 deposit free bonus with 15x wagering requirements. $10 X 15 = $150 you must wager before you can make a withdrawal.

Deposit Bonus

The same equation listed above can be used when solving for your wagering requirements on a deposit bonus.

• Equation: Bonus Money Received X Wagering Requirements = Total Betting Amount

• Example: You make a $1,000 deposit using a 100% deposit match bonus up to $1,000 to receive the maximum $1,000 on your welcome bonus. This welcome bonus has 10x wagering requirements. $1,000 X 10 = $10,000 you must wager before making a withdrawal.

Free Spins Bonus

To calculate the value of your free spins, you must multiply the number of free spins you have received and the amount that each spin is for.

• Equation 1: Number of Free Spins X Free Spin Amount = Total Value of Free Spins

If you have the listed RTP (Return to Player) for the online slot you have been awarded free spins on, you can also determine the projected return on your spins with this equation:

• Equation 2: Total Value of Free Spins X RTP Percentage (as a Decimal) = Projected Return

• Example: You have received 20 free spins of 10 cents per spin on an online slot machine with a 95% RTP. 20 free spins X $0.10 per spin = $2 in total value. $2 in total value X .95 RTP = a projected return of $1.90 on your free spins.

Cashback Bonuses

Cashback bonuses return a certain percentage of your losses to your casino account. You can calculate the amount that will be returned by multiplying your net losses by the cashback percentage you have been awarded listed as a decimal. Net losses are determined by subtracting your total losses from your total wins.

• Equation 1: Total Amount Won on Casino Games - Total Amount Lost on Casino Games = Net Losses

• Equation 2: Net Losses X Cashback Percentage = Cashback Bonus Amount Awarded

• Example: An online casino has awarded you a cashback bonus offer of 2% on your net losses each week. You recorded $300 in net losses this week ($800 in total wins - $1100 in total losses = $300 in net losses). $300 in net losses X .02 cashback percentage = $6 in cashback awarded to your casino account.

Loyalty Rewards

Loyalty points are earned at a certain rate based on the casino games you are playing. You can check your casino's reward program terms and conditions to find out how much money you need to wager on a certain game type to earn a point, and how many points must be earned to receive $1 worth of bonus credits. Multiplying these two numbers together will give you the amount you will need to wager on that game to earn $1 in bonus money.

• Equation: Points Per $1 of Bonus Money X Money Wagered = Number of Points Earned

• Example: Your casino allows you to redeem 550 reward points for $1 in bonus money. Players receive 1 reward point for every $2 they play on slots. 550 points X $2 per point = $1,100 wagered to receive $1 in bonus cash.
