When blackjack moved from land-based casinos to online websites, many players started to question whether the games remained fair. After all, it would be easy for the online casino to simply program an algorithm to ensure that the casino always wins. And the player would have no means of knowing if they were being ripped off behind the scenes. Luckily, all reputable online casinos will have gambling licenses which have strict auditing rules in place. This ensures all the games are above board.
