Hooray for Harrah’s Online Casino Mystery Bonus!

What can be better news to a NJ online casino player like you than knowing that if you play at a certain casino on a certain day, you may win a bonus? It’s being guaranteed you will get a bonus! HarrahsCasino.com has a guaranteed bonus for anyone who makes a qualifying deposit anytime between Wednesday, May 17 and Saturday, May 20. So this is an outstanding opportunity to get your hands on extra bonus money that no Harrah’s Online Casino player can afford to miss. By popular demand, it’s a reprise of the super-exciting Harrah’s Online Casino Mystery Bonus!

Those of you who signed up with HarrahsCasino.com just recently or have yet to join may be puzzled why the casino calls it a “Mystery Bonus.” After all, there is no mystery at all that, just for depositing and playing, you will get a bonus. What a refreshing change from all those other drawings which promise great prizes, but where all but one or handful of players come up empty!  What we don’t have privy to, however, and what will have to remain a complete mystery to you, too, until after the end of the promotion, is the size of your bonus. Sound intriguing?

Both HarrahsCasino.com and sister casino CaesarsCasino.com have offered similar Mystery Bonus promotions before, and each time the response has been tremendous. NJ online casino players love the element of surprise. It’s the built-in feature that makes online gambling such an exciting pastime—you can always expect the unexpected. Add on a Mystery Bonus and the fun factor goes right through the roof!

New HarrahsCasino.com Players Can Get the Mystery Bonus, Too!

All HarrahsCasino.com registered players are invited to participate in this NJ online casino’s current Mystery Bonus promotion. If you are not yet signed up with HarrahsCasino.com, today would be a great day to join. As a new member, you get not only a $10 no deposit required bonus, just for registering, but also a 100% match of your first deposit up to $300. See the HarrahsCasino.com website for the terms and conditions.

Then, as long as you make a second deposit before the end of the promotional period, you will get another bonus. Maybe even the top prize of $250 bonus dollars!

Existing HarrahsCasino.com players need make only one deposit of at least $25 to be eligible for the same Mystery Bonus offer.

How to Claim the Latest HarrahsCasino.com Mystery Bonus

The Mystery Bonus promotion at HarrahsCasino.com kicked off at 12 a.m. Wednesday, May 17 and continues until 11:59 p.m. Saturday, May 20. Here is what you need to do during that time period to unlock your Guaranteed Mystery Bonus and win at least $5 all the way up to $250 in bonus money.

  • Log in to your HarrahsCasino.com account.
  • Go to the deposit screen on the HarrahsCasino.com cashier page.
  • Make a deposit of $25 or more using the code MYSTERY5.

Keep in mind that deposits made at PayNearMe or at the Caesars Casino cashier’s cage in Atlantic City don’t count.

That’s all there is to it. Qualifying  for a NJ online casino bonus couldn’t be easier. But next comes the tough part. You have to wait until Tuesday, May 23 for the big reveal when you will finally find out how much you have won. That is when the random drawing will take place to determine everybody’s prize.

Whether you choose to play or not in the meantime is entirely up to you. No minimum amount of play is required prior to receiving your bonus. In addition, the amount of your play, if any, will have no bearing on the amount of your prize.

The Big Reveal: Distribution of Mystery Bonus Prizes

On Tuesday, May 23, the HarrahsCasino.com Mystery Bonus will cease being a mystery. A random drawing will take place to determine exactly which bonus each eligible participant will receive, and immediately thereafter, your account will be credited accordingly.

As the matrix below shows, a total of 106 names will be drawn.

Prize Matrix:

Winners Prize Estimated Value
1 Winner Bonus Play ($250) $250
5 Winners Bonus Play ($100 per player) $500
Bonus Play ($20 per player) $2000
TOTAL: $2,750


Anyone else who made a deposit of $25 or more between May 17 and May 20 and is thus eligible for a bonus will receive $5 in bonus play.

Wagering Requirements to Clear the Bonus

Prior to your being allowed to withdraw the first $25 of your deposit, as well as the bonus and any related winnings, all bonuses associated with this promotion are subject to the following wagering requirements:

            Slots: 5x bonus

            Roulette: 25x bonus

            Video Poker or Blackjack: 50x bonus

You have 14 days to complete this wagering.

Why the HarrahsCasino.com Mystery Bonus Promotion is Worth Your Time

This promotion is a standout because it combines two of the bonus features that NJ online casino players like best:

  • Zero chance of walking away empty-handed. Everybody who participates gets a bonus!
  • The added surprise and excitement of a drawing to determine the amount of your bonus.

Out of all the players participating in this promotion, only one will be lucky enough to receive the top prize of $250 bonus dollars, and only five players will receive the second prize of $100 bonus dollars, So your odds of either happening to you are slim. However, you have an excellent chance of being one of the 100 players to win a $20 bonus. But even $5 in bonus money isn’t bad.

Whatever your Mystery Bonus prize turns out to be should be regarded as a win. Keep in mind that all you deposited is $25, so even a $20 bonus is an 80% match of your deposit, while a $5 bonus is a 20% match. On the other hand, you could be looking at a 400% or 1,000% deposit match!

One of the best features of this promotion is that you don’t have to be a high roller to cash in. Everyone is on equal footing. It’s nice to see this repeat demonstration of a NJ online casino that appreciates all its players.

Don’t let  an opportunity like this pass you by. Opt in to the HarrahsCasino.com Mystery Bonus promotion today!
