Casino seems new and cool so I decided to give a try. I spend 20 gems then get the 100 credits. Working as intended so far? After that I get an error code when I press play. I try to press play again seeing the 100 credits there and nothing. I close and re open casino to see the credits gone. I don't remember the code error. All I know is it started with a 3 and an admin should be able to track the error down anyway. GL in casino everyone and hopefully the bug won't happen to you.
