In a regular casino, most of the blackjack tables carry the same house rules (regarding things like surrender, splitting, and doubling down) and may or may not include a side bet of some kind. But online, even one website could have tables with different rules and up to three or four kinds of side bets, allowing you to pick the kind of game you want, and enjoy the excitement of side bets at the same time.
The same goes for the other players at the table. In real life, if you want to play blackjack at the only table at your limit, you have to play with the yelling idiot who hits on 19. Not so online, where you can always move away and join another table, or even just decide to play by yourself, it’s up to you.
And if you don’t like what the casino has on offer, you can choose a different one in only a few minutes, which means that you are sure to find an online blackjack table which is fun, entertaining, and perfectly tailored to you.
