I think it's best that you know all the rules of the game. So if you know roulette, for example, I think it would be the best, most fair.
Knowing the rules doesn't make it more fair than the others what if it's a live roulette there's no way to verify each bets since they're rolled by the dealer it'll just come down to trusting their operations. Online casinos have different ways of making their game fair but imo there's no clear winner of which game is the most fair.
Before I was playing different gambling because my friend told me it could help me to gain a lot of money. After we observe the environment of the casino, we did some research about how can we win the game and becomes a millionaire on our first weeks of playing gambling. The luck is with us for a whole month it gives us a lot of financial services to our selves. Most of the time we play blackjack and dice because it is the most enjoyable of all the games they have. But not all the time the lucky is on us the time has come that we need to decide if we were going to take all of our money. In a hard decision with a half percent of winning and we made a mistake on the prediction on dice that cause of our lose.
