Online Casino Bonus Codes

⭐ Online Casino Bonus Codes

Online casinos offer generous bonus money options that can be unlocked with free bonus code.

Welcome bonus are the traditional casino bonus offers where you deposit some money and the casino matches it up to a percentage. They are the most common casino bonus codes for US players and are available widely at PA, NJ and Michigan online casinos.

Caesars Palace Bonus Code – FINDERLAUNCH for up to $1,000

Caesars casino bonus code FINDERLAUNCH has a solid expected value of $634 when playing with the maximum bonus. However, the game selection at Caesars is quite poor, so make sure you’ll find the right games with over 97% return.

To make this casino promo code offer even sweeter, the minimum deposit is only $10, which means that it’s perfect for recretional casino players.

BetMGM Bonus Code – FINDER2500 for up to $2,500

BetMGM Casino and Borgata same the exact same welcome bonus and games. As with the no deposit bonus money, you want to play the high return low variance Blood Suckers. This will give you a whopping $1,847.50 of expected value which is one of the highest among any casino in the US if you play with the maximum value.

On the other hand, the $10 minimum deposit is quite mild, letting people who just want to play casual casino games for real money double their playing money.

Horseshoe Casino Bonus Code – FINDERWW for up to $1K + 20 Spins

Horseshoe Online Casinos is one of the newest additions to the NJ online casinos. Their FINDERWW bonus code gives you a 100% up to $1,000 welcome bonus cash, which has a $863.75 EV with the maximum deposit. The 10x wagering is average on paper, but applies both to deposit and bonus money, so you’ll need to play through a lot.

The welcome offer is rewarded in three parts and has a really tight schedule, so keep that in mind when playing.

Borgata No Deposit Bonus Code – BONUSBOR for $20 Free

Borgata bonus code is the little brother for BetMGM. Unfortunately, the expected value for Borgata bonus is slightly lower than the withdrawal limit. Therefore, instead of lower volatility Blood Suckeres, we suggest that you play White Rabbit with it’s higher volatilty. You’ll either lose casino money or win a bigger win.

Caesars Palace Online Casino no deposit bonus is back. New users in NJ, PA, MI and WV can claim this low wagering no deposit bonus with Caesars Casino bonus code FINDERLAUNCH.

⭐ Free Spins Casino No Deposit Bonus Codes

New and existing users can use free spins and slots no deposit bonus codes to unlock free play for their favorite online games.

Free spins no deposit are hugely popular offers in Europe, but unfortunately we don’t get many promo codes for them in America. Currently, only Bet365 has a free spins bonus code. However, they are only available at NJ and PA no deposit bonus casinos.

Bet365 Bonus Code – 500 Free Spins

Bet365 bonus code may sound attractive, as you get free spins no deposit for 10 days. Unfortunately, it only gives you between $4.8 and $19.2 in value as the number of the daily spins can be anything between 5 and 20. Furthermore, the games offered, are not good, with the best slot machine, Magic Forge, capping at 96.06% RTP.

⭐ How to Maximize The Value From Your Bonus Codes

Now that you know all the possible bonus codes that you can claim, let’s look at how you can get most out of your exclusive bonus codes. There are several key elements which we’ll go through in detail below:

• Bonus Stacking
• Game Selection
• Take Advantage of Bet Size
• Smart Wagering

Bonus Stacking

Bonus stacking is the best way to get the most out of your bonuses. It simply means getting as many bonuses you can, especially if they are no deposit promo codes. The more no deposit promo codes you claim, the better your chances are for making considerable gains. With welcome offers you need to be more careful and mindful of variance and your bankroll. Even if the expected value would be on your side, you can’t be sure that you won’t lose all of your money due to bad luck.

Game Selection

Always choose high rtp slots or casino games for your bonus wagering. This way you have a higher chance of actually making some money from the casino. To calculate how much (on average) you should be winning, you can use this simple formula.

BonusFinder Tip

(Bonus Amount × Payout Rate) − (Wagering Requirement × House Edge) = Your Potential Winnings.
If you're playing Blood Suckers with 98% RTP with BetMGM Casino $25 no deposit bonus and 1x wagering, the calculation would be 100/98 × $25 × 1 = $24.5. As long as you're expected value is above the withdrawal limit, there's value in your casino bonus code

Maximum Bet Size

Especially with welcome bonuses with high wagering, you want to take advantage of the max bet size since you need to win big early on to have more chances of playing through your welcome bonus cash. We generally recommend a bet size of $5 – $10 for welcome bonus codes and between $2 to $5 for no deposit bonus codes.

However, if you’re just playing for fun, rather choose a smalelr bet size. This way your hard earned money will last longer while you’re having fun.

Smart Wagering

Always wager your funds smartly. This means changing the games you are playing based on how much you are up. If you start with a high volatility game and 5x your bonus package, you should switch to a lower volatility game with more consistent returns to keep most of what you’ve already won.

Vice versa, if you’re down to your last dollars, it’s pointless to play games that will only give you small wins as the game will eventually grind you down.

⭐ Common Mistakes With Casino Bonus Codes

There are a few key things you should be aware when claiming casino bonuses. We’re sure you’re aware of wagering requirements and withdrawal limits at this point as we’ve specified them for every offer, but let’s look at couple of other things where things often go South.

• Restricted Games
• Time Limits
• Restricted Payment Methods
• Unregulated Bonuses

Restricted Games

Casino promo codes will rarely let you play games with high return to player such as blackjack or roulette. The most common available games are real money slots, but even some of the best slots can be restricted.

Therefore, it’s important to always read the T&Cs set by the casino to see what games are eligible for bonus wagering requirement. For casinos in this list we’ve specified the best games, but if you feel like switching it up, make sure your game is not on the banned list.

Time Limits

Some casinos like BetMGM and Borgata have strict time limits attached to their bonuses. For example, these two casinos only give you 3 days to wager through your no-deposit bonus. Even though this is plenty of time to do it, you shouldn’t forget it, as the bonus money will expire and you’ll lose it.

Payment Methods

US online casinos generally accept most payment methods for bonuses such as PayPal, Cash App, and Credit Cards. However, some casinos don’t take certain credit cards like Amex, and almost no casino let’s you claim bonuses with PayNearMe. Therefore, make sure that you’re payment (and withdrawal!) methods work before committing to a casino.

Unregulated Bonuses

At Bonusfinder.com we maintain an extensive list of blacklisted online casinos that are either illegal or try to scam you. Unfortunately many of these casinos still advertise on the internet. Therefore, always look for a US license when registering at a new online casino.
