That's the reality, there's no pattern to follow when it comes to gambling. All of those games are programmed randomly so that everyone will play fairly and for the safety of all players. Your luck is still the one who will dictate your fate in playing online casino. Luck is the essential thing in gambling, that will help you to win more money.
If you are playing on any program casino and all players and dealers are computer there's no way to defeat them because we don't know if they are actually fair or not.
Unlike real casino and live casino that I'm sure they are fair compared to program casino games.
Everything in gambling are always depends in your luck so if you are not lucky then you will lose and also if you are greedy and you are not satisfied on the amount you win then you will still lose it in the end unless if you win again in your last bet and you decided to withdraw we can consider it as a win.
