The business of US online casino sites for real money is competitive, with many brands vying for the attention and bankrolls of bettors. Online casino bonuses are part of licensees' efforts to not just win over new customers but keep them as well.
How US Online Casinos Reward Player Loyalty
Legal U.S. online casinos utilize two primary methods to retain customers. The first of those, an explicit loyalty program, is obvious.
Online casinos also offer frequent promotions in their apps and on their websites that all players can choose to take advantage of. The combination of these two elements separates the brands that do the least and the most to reward players for their patronage.
How Do Loyalty Programs Work at Online Casinos?
Each different online casino has its proprietary loyalty program, like BetMGM Rewards and Caesars Rewards, as just two examples. While there is a lot of deviation between many elements of these programs, the basic premise is universal.
In all of these programs, players get rewards points and/or tier credits for placing real-money bets on online casino games. Players can then choose how to redeem those points for things like free play or other benefits.
Are Promos for Existing Players Different from Welcome Promos?
The biggest difference between most promotions for existing players and new user bonuses is the value of the deals. Online casinos typically reserve their most valuable promos for new players.
Otherwise, the formats are quite similar. Promos for existing players often consist of offers like deposit matches, casino credit for betting on certain games, and more.
Which Online Casinos Have the Best Loyalty Programs?
The value of a US online casino's loyalty program will differ based on what you prioritize most highly. Various loyalty programs emphasize different aspects of their systems.
For example, BetMGM Rewards and Caesars Rewards lean toward providing perks for people who visit Caesars Entertainment and MGM Resorts' land-based casinos. Meanwhile, the FanDuel Casino Rewards Club and Dynasty Rewards at either DraftKings Casino or Golden Nugget Casino put more emphasis on bonuses you can enjoy online.
Alternatively, the Fanatics ONE program at Fanatics Casino gets high marks from players for flexibility. It's also a popular program among online casino players who also happen to be big fans of live music or sports or avid collectors.
There also isn't a lot of separation between these brands in terms of in-app promotions.
Which Online Casinos Have the Most Valuable Promos?
Depending on your taste in games and how you like to play, the answer to this question could shift frequently. You'll find a few basic formats with slight tweaks at different times on the various licensed online casino apps.
Because of the diversity of available apps for players in Michigan, New Jersey, Pennsylvania, and West Virginia, it can actually pay to be disloyal to an extent. If there is a particular type of promo that you prefer, it can be beneficial to check several apps to look for a deal that fits your bankroll and preferences.
Common Types of Online Casino Promos
Bet and Get — a bonus that is applied to your account after you place a qualifying wager
Bonus Plays — plays of participating games that don't require a stake from your bankroll
Deposit Bonus — a bonus that you receive following a qualifying real-money deposit
Tournament — limited-time contests in which players receive bonuses according to standing on event leaderboards
With all of these offers and the loyalty programs, the most important thing is to know what you're getting into. Reading and understanding the terms and conditions is pivotal.
Common Online Casino Bonus Terms and Conditions
When it comes to loyalty programs, many do not award an equal amount of rewards points or tier credits for bets on all games. With Caesars Rewards, for example, you earn one reward credit and one tier credit for each $5 in real-money bets on slots, but you have to make $25 in real-money bets on all other games to get the same return.
With promotions, players should look for:
Expiration dates, both on the offers and any bonuses from the offers
Minimum real-money amounts necessary to deposit or wager
Playthrough requirements for bonuses resulting from the deals
Restrictions on which games participate in the promotion or bonuses are valid on
Taking all these circumstances into account, six online casino brands stick out for offering valuable and versatile bonuses for all players. In alphabetical order, those are as follows.
BetMGM Casino: Strong Value for Players in Michigan and New Jersey
If you live in or frequently visit Michigan or New Jersey, BetMGM Casino's package of BetMGM Rewards and in-app promotions is worth consideration. That's because BetMGM Rewards gives you lots of options for ways to utilize your rewards and flex your tier status at the MGM Grand Casino in Detroit and the Borgata Casino Hotel & Spa in Atlantic City.
These perks can include comped dining, hotel stays, parking, and spa treatments. In addition, there is the option to redeem your points for free play either online or at the aforementioned physical casino.
BetMGM's rotation of bonuses on the app is somewhat unique because of its prominent highlighting of player sweepstakes. You will find the standard items like deposit bonuses and tournaments.
Caesars Palace Online Casino: A Win for Pennsylvanians and Travelers
The biggest upside of the Caesars Rewards program is how many other companies are integrated into the program, especially those that offer products or services related to travel. There's also great value in Caesars Rewards for people in PA because of the presence of the physical Harrah's Philadelphia casino.
The redemption rate for Caesars Rewards points for play in Caesars Palace Online Casino is strong at 1:1. This can be a valuable perk if you like to try new online casino games.
Caesars' collection of promos also emphasizes new additions to its library. You'll often see bonus spins offers for new slots, as one example.
DraftKings Casino and Golden Nugget Casino: Generous Earning Rates and Lots of Contests for Slot Players
DraftKings owns and operates Golden Nugget's online casino, so both utilize the same Dynasty Rewards program and offer the same promotions depending on jurisdiction. A real asset for Dynasty Rewards is the rate at which you can earn crowns (rewards points) by playing slots.
While BetMGM and Caesars give you a reward point for every $5 in real-money bets, Dynasty awards a crown for every $2 in wagers. Rates for other types of games in Dynasty Rewards are competitive, too.
Promotions at DraftKings Casino and Golden Nugget Casino complement Dynasty Rewards through highlighting featured games. Slot tournaments are essentially a mainstay on both apps.
Fanatics Casino: Flexible FanCash and Daily Bonus Spins
Bonuses for existing players at Fanatics Casino center heavily on the company's currency. FanCash, which is the currency of the Fanatics ONE program, is available both as a bonus and a prize.
There are daily chances at FanCash that you don't have to risk any of your bankroll for in the app, as well as regular sweepstakes with FanCash as the prize. FanCash matches other rewards points in terms of being good for online casino play at Fanatics at a 1:1 rate.
No other online casino on this list can match Fanatics ONE for value if you want to use your rewards for collectibles or fan merchandise. Otherwise, promos focus on promoting exclusive games on the Fanatics Casino app.
FanDuel Casino: Best for Players With Diverse Interests
If your favorite ways to play online casino games fluctuate or you aren't yet sure what those are, FanDuel Casino is worth a look. You'll regularly find promos promoting exclusive slots, table games, and chances at daily jackpot prizes.
The other stellar aspect of FanDuel's value for bonus seekers is the earning rate for rewards points. You receive three points for each dollar in real-money bets on slots and other FanDuel Jackpot games, for example.
You really can't go wrong with any of these online casinos when it comes to bonus value for all players. It's really just a matter of which rewards you enjoy the most.
