Ratings and Reviews
While playing Lobstermania3 I got the buoy bonus. Before the bonus started your app froze. I gave her several minutes to see if it would change and it did not so I logged out and log back in. I went back into the game and it gave me the option to recover my bonus. It had me spin again and it gave me the boy bonus as well as a wheel bonus. I was able to play the wheel bonus and got two extra spins and ended winning five. 4 million. However as the game went to play the buoy bonus it froze again. I repeated the same steps left out, logged back in, and when I went back into the room I was not given the option to recover my bonus. I was also not paid the 5.4 million that I won on the wheel bonus. I do have screenshots of this as well. Is there any way for me to get to play the bonus I won or receive the payout for the bonus I was able to play?
Nice casino as far as online casinos go.....BUT....they need to rethink the cost of purchasing credits. To spend $99 for just 100,000,000 credits is very excessive. $100,000,000 credits lasts no time in these casino games. Plus you very seldom experience any real big wins. Many other casinos have very generous offers, so I chose to support them. For $24 on another very realistic casino(with games you see in real casinos) I have purchased over $3,000,000,000 credits. Enough to play and be entertained for a long time. It’s really a shame that Double Down Ft. Knox is pinching pennies, when with generous offers and more generous wins they could be enticing more players to purchase more credits. After all this is not a REAL casino where you have the chance to win REAL money....so the developers do not need to apply REAL casino odds to their games. Be generous with credits and wins and they will be rewarded with generous purchases. Win win for all parties involved.

Visually beautiful but bonuses are impossible.
This game is beautiful but this app gets pretty boring unless you play Golden Egypt. That seems to be the only game where bonuses hit and the wild options actually give you a chance to go up in your chip count. This is the only game that has actually entertained me and seems to play fairly.
Siberian Storm’s animation is way too long/slow and the “Slam button” option on anything almost guarantees no return on your bet- it’s incredibly boring between the slow speed, lack of hits, and drought in bonuses.
You can literally play games for over an hour with no bonuses triggered in Fort Knox. I bet I’ve put in 6 cumulative hours of play into King of Macedonia and triggered the bonus a grand total... of once. The progressives are a joke, no matter what you do, you’ll only hit the bronze and OCCASIONALLY the silver.
That being said, the Lucky Cat bonus and multiplier bonus chips at varying levels is a welcome feature.
Fort Knox has a lot of potential but the games play WAY too tight for something that doesn’t involve actual money. All of the King Reels games are beautiful to look at but horrible (Turquoise Princess, Dark and Stormy, and Farmers Daughter) and not even worth playing between low return, even on regular spins.
