As long as you’re playing at a legit casino, you’ll find that Keno and all their other games are fair and above board.
Each draw is done via a random number generator, and the games are independently audited. So there’s no way for the casino to cheat even if they wanted to (although any top casino would value their reputation and future business far too much).
That’s not to say that there aren’t any scam online casinos out there. Of course there are plenty – but that’s why you have an independent team like ours to review and test them. This means you can stick to the genuine casino sites and avoid the dodgy ones.
