Not to mention, we're talking about a game where the online site that has the most far play.
In my opinion, it's poker, because it's a game I know and the site doesn't ask so much about your stake and winnings, that's reason enough for the site not to steal from you.
The site may give you bad tickets, but again it knows whether or not to get one.
If sellcted others, clarify which game and why?
The question is wrongly framed. A reputed site can make every game fair while a scammy site can be unfair on all the games. Poker can be easily cheated really!
Imagine a site that promises live deals on Poker and just uses bots instead? How'd you verify any of that?
Bots are easily outplayed after 30-40 minutes of studying their behavior. A friend of mine opened a poker site 3 years ago, installed bots, and, being not a cheater, told potential players their names. What happened next was he lost thousands of USD over the course of few months, and closed the site. (He could lose more but the bots were playing on low stakes only). So, I think poker bots constitute more of a problem for the site owners than for the users.
I agree with the posters who say that the game itself doesn't matter in regards to fairness. What matters is how the outcomes are obtained. You can make absolutely any game either fair or unfair, depending on the algorithm behind it.
