In particular, if the player uses card counting, his chances of winning increase quite a lot. At the same time, the casino will still benefit from this game in the long run. This is not because the dealer is cheating customers, but solely because the rules of blackjack give him an advantage over gamers.

House Edge in Slot Machines

If we talk about the most popular games in online casinos, it certainly will be slot machines. Now, in almost every casino you can find dozens or even hundreds of slots with a wide variety of themes. However, this issue is not without fraud. Most institutions use slots from well-known developers where you can’t affect the RTP size.
