Before you even step foot into a casino or log in, you must establish how to avoid biting off more than you can chew. First off, decide your bankroll AKA how much you're willing to lose and or spend. Once you have hit the limit you set for yourself then it’s time to walk away, even if you weren't able to win big that night. Additionally, most players will agree that it’s wise to walk away when the number of times you’ve won and lost are the same or you make a big win.
