Types of Betting Bonuses Offered by US Online Casinos 

Free stuff. Who doesn’t enjoy getting something for nothing? In the competitive online casino industry, that’s just what they offer new players via their lucrative signup bonus packages. 

As well, the best online casinos continue to take care of their players with ongoing promotional and bonus offerings.  

Welcome Offers

Knowing how many online casinos are out there, sites roll out the welcome mat to lure players with sizable signup offers. These generally consist of three types of bonuses – free play, free cash and matching deposit bonuses.

Free play is an amount of money awarded to a player for signing up at a site. For instance, Golden Nugget delivers $30 in free play to newcomers.

Free cash is money awarded to players just for opening an account. BetMGM includes $25 in cash to new players. 

The matching first deposit tends to provide the biggest reward. At Unibet, they provide new signups with a 100 percent matching first deposit that can reach up to $750. 

Refer A Friend Bonus

It pays to have friends. And the more friends you have, the more it can pay off. FanDuel is one casino that offers a refer a friend bonus. Players are assigned a referral code upon signing up. Get a friend to join FanDuel and if they enter that referral code, both you and them will each garner up to $100 in bonus play.   

Reward Multipliers

Often rewarded in the form of free spins, game specific bonus offers are usually designed to serve the purpose of getting players to try out a new slot machine.

This type of bonus is serving a twofold purpose for the online casinos. Firstly, they are a method of engaging customers to keep them playing at a site. Secondly, it’s also a way to get players to give a try to a new game or slot machine.

A reward multiplier will be attached to a certain casino game for a specific limited time period. When players play this game, they will see their winnings multiplied to a higher level. Generally, the amount will be two or three times the usual payout, although on rare occasions the rewards will be much higher, sometimes even as much as 100 times over the standard stipend. 

Loyalty Rewards

This is another form of bonus that can take on a variety of options in its offerings. Loyalty rewards are designed to thank longtime, regular players for their continued patronage and let them know that they are appreciated.

One method for casinos to show loyalty is by awarding cash back to players for regularly playing a certain game. The most popular form of loyalty rewards are perks offered to regular players who collect awards points every time they play in the casino. These rewards can consist of everything from free spins on games, to free entry into tournaments, to merchandise and even stays at the site’s brick and mortar casino partner.

An example of this is Caesars. Through their Total Rewards VIP program, they provide players as much as 20 percent discount on gift shop items, VIP reservation status, discounts on dining and invites to exclusive events.

Cashback Bonuses

Online casinos will provide cashback rewards to players. The amount of the cashback awarded to a player will be determined based solely on volume of play. The more a customer is wagering inside the casino, the higher percentage rate of their cashback rewards will be. 

High Roller Rewards

Those who play in the big leagues of online casino gambling and wager massive sums of money will find that they will be welcomed into the perks of an online casino’s high roller club. Generally, players who deposit $500 or more into their online casino account can count on receiving the high roller treatment. 

Membership in this club certainly has its privileges. At DraftKings for instance, high rollers can access a 100 percent matching deposit bonus that’s worth up to $1500.

Wagering Requirements 

Be sure to read the terms and conditions. You’ll get that advice with any offer that you sign up for and online casinos are no exception to this common sense rule.

Every online casino will attach wagering requirements to bonus offers. This refers to the number of times a player will need to wager the bonus amount in order to clear it for withdrawal from their account. Look around at the top US online casinos and you’ll find that there is a wide variance in this requirement.

For example, there’s a 30x rollover necessary at 888 Casino. On the other hand, SugarHouse requires a minimal 1x rollover as a wagering requirement. 

There could be other restrictions in place. Some sites may attach the rollover to both the deposit and the bonus. Other sites might only allow winnings from the bonus to be withdrawn and not the actual bonus amount.

Types Of Games Offered At US Online Casinos

Whether you keep it simple and play the slots, or you prefer the excitement and the challenge of the table games or poker rooms, there’s enough variety available from the leading US online casino sites to keep everyone satisfied and happy.

Here’s a rundown on the some of the games available to be played through USA-based online casinos:

Online Real Money Slots

Slot machines are the most common and popular game in brick and mortar casinos, and the same holds true inside online casinos. Players will find hundreds of slot games to try at the top US online casino sites. The variety of games to play include Vegas slots, traditional fruit-based machines, film and TV or music themes, and fantasy games.

Jackpot Slots

Regular slots offer a fixed amount of money that can be won. With jackpot slots, the potential awards can be massive. The jackpot grows with every play of the machine, which is why these games are known as progressive jackpots. Often, these jackpots will be spread across more than one casino, increasing the potential for a payoff that could be in the millions of dollars.

Blackjack

The simplest of the table games, this card game is also commonly known as 21. Players compete against the house rather than each other. Whichever hand between the player and dealer comes closest to 21 without going over, wins that hand. 

Roulette

Roulette involves a dealer spinning a wheel and releasing a ball to twirl around the colored and numbered roulette wheel. Players compete against the house. They can bet on a specific number, a color, all of the odd or even numbers, or even a range of 38 numbers including 0, 00 and 1 through 36.

Baccarat

Baccarat is an exciting game of pure chance, at its essence a simple guessing game. It’s an easy, slow-paced game that’s great for new players, because there’s no strategy or skill involved. It’s a bet on which hand dealt will be higher, the player or the dealer. As well, baccarat offers some of the best odds in the casino.

Craps

Considered the fastest game in the casino, for many, craps is also the most thrilling. It’s a dice game that’s played on a specially-designed table where players place their bets based on what they believe the outcome of the next roll of the dice will be.

Video Poker

While similar to slot machines in that a random number generator deals the cards, video poker is different from a slot machine in that there are only a certain number of outcomes, and those outcomes are known to the player. There’s also an element of skill involved as players decide which cards to keep and which ones to discard prior to spinning again.

Poker

Online casinos offer real money poker games in which players can play with either a virtual or a live dealer. The variety of poker games offered includes Texas hold ’em, stud poker, and five-card draw. There are even high-stakes tournaments provided.

Keno

The popular brick-and-mortar casino game in which players pick numbers similar to filling out a lottery ticket is also available through US online casinos.

Slingo

An online game that is a hybrid of bingo and slot machines, Slingo is offered at many US online casinos. Players are given a grid of numbers similar to a bingo card. Then they spin a five-wheel slot and when the numbers stop, check and see if any match the numbers of their grid. Players accumulate game points with every spin. 

Live Dealer US Online Casino

The newest addition to the online casino entity, live dealer games offer the player as close an environment to being in an actual casino without the need to get in the car and drive there. All of the popular table games are delivered to players with live streaming and interaction between players and actual dealers inside a studio.
