Casinos build a great business by attracting more people to their place and providing offers that entice them to return. And we, as gambling players, whether small or big gamblers, must try to limit finances when playing. Otherwise, we will only regret having made an unwise decision.
It's really important to limit ourselves when playing, only use what you can afford to lose. Hence even if you didn't win, it's easy to accept it since you're prepared for the worse to happen and that is by losing your money. However, many of us forget this simple rule when playing and exceeding their limit for trying to recover the losses which is not right.
I'm just an average gambler too and aware of how risky gambling is and the edge of the house. Thus, I often play a skill based game wherein knowledge and strategy are necessary to win. Anyway we have different preference and it depends on us what games we most enjoy when we gamble.
