Guaranteed Mystery Bonus at Harrah’s Online


If you’re still not convinced that even a small NJ online casino can be worth your time, look no further than What the site lacks in sheer number of games it more than makes up for in the quality of its special promotions. This weekend one of the most popular special offers at Harrah’s–the Guaranteed Mystery Bonus—is back. Just like every time Harrah’s had this great offer before, you don’t know ahead of time what your bonus will be. However, everyone who participates is guaranteed to win something!

I don’t know if this will be the last Guaranteed Mystery Bonus Harrah’s will offer you in 2018, but it certainly isn’t the first. The identical offer has been repeated so often I have lost count, but I do know that I have highlighted it here on a number of times, including as recently as this past October. That makes me reasonably certain you’ll see it again in 2019. But why wait till then? If you’re a Harrah’s Online Casino player, you can’t afford to let what could be your last opportunity to let this guaranteed bonus this year get away from you.

How to Claim the Latest Harrah’s Online Casino Mystery Bonus

The period for claiming the current Guaranteed Mystery Bonus started on Thursday, December 6 and ends at 11:59 p.m. Sunday, December 9. Whether you opt in at the beginning of the promotion or on the last day has no bearing on the size of your bonus. So you still have time and the same chance as earlier players to win the top prize. But you will have to hurry. These are the simple steps that you will need to follow.

  • Log into your account before 11:59 p.m. Sunday, December 9.
  • Make a single deposit of $25 or more, using the bonus code MYSTERY.

As soon as your qualifying deposit is received, your Guaranteed Mystery Bonus will be revealed and credited to your account in the form of Bonus Play instantly. Just like in the past, there are three possible amounts you can receive–$10, $25, or $50. All amounts are randomly determined and not in any way influenced by prior play or the size of your deposit. Furthermore, you can only claim this offer one time and deposits made at the Caesars Atlantic City casino cashier’s cage or via PayNearMe don’t count.

Mystery Bonus Wagering Requirements

The only feature of the Mystery Bonus that is a mystery is the size of your bonus. Everything else about the offer is unchanged from before, including the wagering requirements.

You can clear the bonus with any game you please. However, if money is tight, your best bet is to stick to slots since the wagering requirements are much more reasonable. Depending on your game choice, these are the casino’s wagering requirements for clearing the bonus:

  • Slots: 5x bonus
  • Roulette: 25x bonus
  • Video Poker or Blackjack: 50x bonus

Regardless of which game you select, the allotted time to complete the wagering is the same—up to seven days. Until the bonus is fully cleared, the bonus, deposit tied to the bonus, and any resulting winnings remain temporarily locked into your account. Once the necessary wagering is completed, provided it is within the allotted time frame, you will have full access to this money (or whatever is left of it).

Keep in mind that canceling the bonus, attempting to withdraw unavailable bonus related funds prematurely, or failure to complete the required wagering on time will result in forfeiture of both the bonus and any resulting winnings.

Why Harrah’s Online Casino Players Love This Offer and Can’t Get Enough of It

Judging by the frequency with which this Guaranteed Mystery Bonus keeps cropping up again and again, Harrah’s Online Casino players love the offer and can’t get enough of it. It’s easy to understand why.

Everyone can afford it

For starters, it’s an offer that everyone, even the smallest players, can access. All you have to deposit is $25.

Your bonus is guaranteed

If you make the minimum deposit of $25 (which you should to get the maximum benefit of the offer), at the very least you will receive a $10 bonus, which isn’t much, but it’s a 40% match on your deposit. But you could also receive a bonus of $25 for a 100% deposit match or even a bonus of $50 for a 200% deposit match!

If you clear the bonus with slots, you only have to wager the bonus 5x

As long as you’re willing to clear your bonus with slots, you can get by with a minimal wagering requirement of just 5x the bonus. Since most NJ online casinos impose a 10x bonus or higher wagering requirement for slots, you are getting a real bargain.

Depending on whether your bonus is $10, $25, or $50, your total wagering requirement will be $50, $125, or $250. And don’t forget, you can take up to a full week to complete the wagering.

But for best results, don’t just randomly play any slots. Try to select slot games with a 96 percent return or better. This will help you preserve your bankroll and give you a better chance to win.

It’s a Mystery Bonus, which makes the offer even more fun.

Last but certainly not least, what casino gambler doesn’t love the added fun and excitement of a good mystery?  Knowing for certain that you will get a bonus, but not knowing ahead of time how much has to make you chomping at the bit to find out.

In summary, what makes the Mystery Bonus a great offer is not that you or any other player could win a fortune (highly unlikely since all of the bonuses are small), but the opportunity for an easy guaranteed bonus with minimal risk.

Don’t pass up what could be your last chance this year to unlock another Guaranteed Mystery Bonus at Harrah’s Online Casino!.
