Mystery Bonus up to $50 at Harrah’s Online


There’s no mystery about it. Bonuses from your favorite NJ online casino are always a welcome extra, but online players especially love a Mystery Bonus. It’s because of the extra excitement of not knowing ahead of time what you are going to get.

What makes this Mystery Bonus from even better, though, is that everyone is going to get something!

Tired of drawings where only a handful of players win anything? This is not a drawing. Every player who participates gets a prize!

When the Harrah’s Online Casino Mystery Bonus is Being Offered

This promotion is available from Wednesday, February 7 through Saturday, February 10. You can only claim the offer once, however. So choose whichever of these days is most convenient and claim your bonus by doing the following.

  • Log into your account anytime during the 2/7-2/11 promotion period.
  • Using the bonus code MYSTERY2, make the required deposit specified in the marketing collateral and claim your bonus.

Surprisingly, the promotion page on the casino’s website does not indicate the amount you need to deposit. If you have not received an email providing this information, be sure to contact Customer Support and get the answer to this important question. Also note that deposits made at the Caesars Atlantic City casino cashier’s cage or via PayNearMe don’t count.

Upon receipt of your qualifying deposit, the casino will immediately randomly award you one of the following three bonuses:

  • $10 in bonus play
  • $25 in bonus play
  • $50 in bonus play

 Wagering Requirements for the Mystery Bonus

Here are the specific requirements for each bonus cleared with each type of game.

$10 bonus

  •  Slots: $50
  • Roulette: $250
  • Other Games: $500

 $25 bonus       

  •  Slots: $125
  • Roulette: $625
  • Other Games: $1,250

$50 bonus

  • Slots: $250
  • Roulette: $,250
  • Other Games: $2,500

You have 7 days to complete the necessary wagering. Failure to complete the wagering within that time frame or any attempted premature withdrawal of the bonus or funds locked into the bonus will result in forfeiture of both the bonus and any resulting winnings.

Is the Mystery Bonus Worth Your Time?

Harrah’s Online Casino doesn’t offer bonuses as frequently as some of the other NJ online casinos. That doesn’t mean at all that the Harrah’s offers aren’t good. On the contrary, most of them are very good, but because the casino doesn’t make them available that frequently, you should make it a point to grab them when you can.

The wagering requirements are reasonable, especially since you are given an entire week to complete them. Therefore, there is no need to rush to get all of the wagering done in one day. Take your time, especially if you are a small player and not accustomed to wagering large amounts of money in a single day.

Unfortunately, if you want to clear the bonus playing the games with the lowest house edge–video poker or blackjack–the  playthrough requirement increases substantially to 50x the bonus. However, even that amount should be manageable spread out over the full seven day period, especially when combined with some slot play to make the total wagering requirement less.


The Mystery Bonus is a good offer. Granted, none of the possible bonuses are huge, but at least they are accessible to any player, whereas, once you factor in the deposit and wagering requirements, a very large bonus might not be. Lastly, it’s hard to imagine any online casino player not liking a good mystery bonus!
