One thing that you should know is that the caaino algorithm software is designed to favor the casino no matter how hard you try. Gambling is a game of luck and slot is a pure luck based game which makes your wins strictly by luck.

I have also experienced this too. Since it's a repetitive pattern when gambling on slots, you should take advantage of your early win and quit the game instead of you to continue playing hoping to win more. However, that is how gambling works, if you are not satisfied with the little profit that you have already, you will lose everything back to the casino. It's not only on slot games.
