I do not think that the casino is lucky that they are closed. I think you got lucky the casino is closed. With that kind of mentality, you are going to get wiped off your money. Usually in gambling, when you are forcing yourself to win back the money you lost, you lose more money. You have no control if you are going to win or not in a casino. Most games are luck based so if you are forcing for revenge, your luck runs dry. You will just lose more money.

Anyway, hope you did not come back the next day with the same mentality. Just let go of your losses and enjoy the game. Don't stress yourself since you said that you already gain some of the money lost in other games.

Good luck with your gambling.
