Mystery Bonus Promo is Back at Harrah’s


Regardless of whether you’re a slot player, table games player or both, getting your greedy hands on as many good bonuses as possible is the name of the game. However, anytime the bonus is not only guaranteed, but the amount is a mystery, the fun and excitement of playing for it and your determination to get it intensify. That’s what makes mystery bonuses a favorite with players. It’s also the reason why they keep popping up again and again at NJ online casinos, like during this week’s Mystery Bonus promo at Harrah’s Online Casino.

How to Participate in the Mystery Bonus Promo at Harrah’s Online Casino

If you’re a player, this is a promotion you won’t want to miss. The offer starts Thursday, June 7 and continues all weekend through Sunday, June 10, so pick whichever of those four days is most convenient. Getting your Mystery Bonus is easy, too. All you have to do is the following:

  • Log into your account anytime during the June 7-10 promotion period.
  • Make a qualifying deposit, as specified in the marketing collateral, using the bonus code MYSTERY6.
Terms and Conditions

As soon as your qualifying deposit is registered, your special Mystery Bonus will be credited to your account immediately. If you wish to deposit only the minimum and are not sure what that amount is, you should contact Customer Support beforehand. This offer can only be claimed once. Deposits made at the Caesars Atlantic City casino cashier’s cage or via PayNearMe don’t count.

What Size Bonus Can You Expect in the Harrah’s Mystery Bonus Promo?

 The size of your bonus will be randomly decided,. However, in all cases will be one of the following amounts:

  • $10
  • $25
  • $50

The size of your deposit (provided it is at least the minimum) and level of previous play will have no bearing on which size bonus you are awarded. Depositing more than the minimum will not increase the size of your bonus.

Wagering Requirements

 Your $10, $25, or $50 Mystery Bonus is subject to the following wagering requirements:

  • Slots: 5x bonus
  • Roulette: 25x bonus
  • All Other Games: 50x bonus

Therefore, if your bonus is $10, depending on which game you choose, you will need to wager $50, $250, or $500. Or, for a $25 bonus, the corresponding wagering requirements are $125, $625, or $1,250. Or, if you are lucky enough to get a $50 bonus, the respective wagering requirements are double those amounts–$250, $1,250, or $2,500.

You have up to seven days to complete the wagering. This should be ample time, especially if you clear the bonus primarily or exclusively with slots. While the bonus is still in progress, you will be temporarily unable to withdraw either the bonus itself or any winnings therefrom. You will have access to these funds  upon satisfactory completion of the necessary wagering. However, cancelling the bonus, any premature attempted withdrawal of unavailable funds, or failure to complete the wagering within the allotted time frame will result in forfeiture of both the bonus and any resulting winnings.

Is the Mystery Bonus Promo at Worth Your Time?

This promotion is worth your time because it’s an easy way for any registered player at Harrah’s Online Casino to get a guaranteed bonus, although in all likelihood a small one. Bigger players will be disappointed that the maximum bonus is only $50, and obviously, a bonus of only $10 or $25 would be almost meaningless to any player whose average bet is many times that amount.

However, the Harrah’s Online Casino Mystery Bonus promo is a great offer for small stakes players who might rarely qualify for a bonus otherwise. Therefore, the best way to approach it is to accept it for what is meant to be—a fun way to get a little extra betting money into your account. It is not the type of promotion offering more than a very remote chance for a huge win.
