Harrah’s Guaranteed Mystery Bonus is Back!


As an online casino player, one of the special perks you get to enjoy often is being pleasantly surprised. As nice as it is to learn from the casino not only that you are about to receive a bonus but how much, it’s even more fun when you’re simply informed that a bonus is coming and have no idea how much. So if you like to play on HarrahsCasino.com, this mid-September weekend is the perfect time. By popular demand, one of your favorite bonuses at Harrah’s Online CasinoHarrah’s Guaranteed Mystery Bonus–is back again!

A Mystery Bonus is in some ways like entering a prize drawing or pressing the lever on your favorite slot machine. In all three cases, while you’re hoping for the best, you have no idea ahead of time what will happen. However, this Mystery Bonus is in one respect different from and better than the other types of surprises mentioned because no one walks away empty-handed. Every player is guaranteed to win something!

How the Guaranteed Mystery Bonus Promotion at Harrah’s Online Casino Works

The Guaranteed Mystery Bonus at Harrah’s Online Casino started Thursday, September 13 and continues through Sunday, September 16. So if you’re a HarrahsCasino.com player and haven’t logged in and claimed your bonus yet, what are you waiting for? You only have until 11:59 p.m. September 16, after which this promotion will be over.

Everyone who participates is guaranteed to receive one of these three bonuses: $10, $25, or $50. Here’s what you need to do to participate.

  • Log into your HarrahsCasino.com account during the 9/13-9/16 promotion period.
  • Make a qualifying deposit using the code MYSTERY 9.

Your $10, $25, or $50 bonus will be credited to your account immediately.

Additional Considerations

The casino website doesn’t specify what the minimum deposit is to qualify for a bonus, so check the marketing collateral or with Customer Service to be certain you are depositing enough. No need to deposit more than the minimum since the size of your deposit will have no bearing on the size of your bonus, which is randomly determined.

Also note that this offer can only be claimed once and requires a single deposit. Deposits made at the Caesars Atlantic City casino cashier’s cage or via PayNearMe won’t count.

Harrah’s Guaranteed Mystery Bonus Wagering Requirements

Before you will be permitted to withdraw your bonus or any winnings resulting from it, you will need to meet the casino’s wagering requirements, which are as follows:

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

You have up to seven days to complete the wagering. Then, as soon as the bonus is cleared, assuming the seven days wagering period has not elapsed, both the bonus and any winnings therefrom (or whatever is left of this money) will become available for withdrawal.

However, as with any other bonus, canceling the bonus, attempting to withdraw unavailable funds prematurely, or failure to complete the wagering in time will result in forfeiture of both the bonus and any resulting winnings.

Why the Harrah’s Guaranteed Mystery Bonus is a Good Offer

If you’re a big player you are likely to be disappointed by the meager size of this bonus. Even the maximum possible bonus of $50 won’t seem like much if your average bet is for many times that amount while, obviously a $10 or $25 bonus would be almost meaningless.

On the other hand, if you’re a small player, this offer is tailor-made for you. A minimal deposit should be all that’s required, and then you have a full week to satisfy the wagering requirements for clearing the bonus.

Because all of the bonuses are small, it’s best not to get your hopes up that this promotion will be a huge money maker for you. Instead, enjoy it for the affordable but fun and potentially profitable promotion it is, with the added fun and excitement that you can only find in a Mystery Bonus. And since your bonus is guaranteed, it would be silly not to take it!
