Blackjack Hero covers the basics of how to play blackjack, but you can't really play blackjack online here. But any number of online casinos offer blackjack games. These online blackjack sites offer mostly similar services: the ability to play online blackjack for free or for real money. Usually they offer multiple variations of blackjack for you to try.
I've tried to provide some guidance about what kinds of online blackjack are offered at some of the better casinos sites here. I've included information about what kinds of signup bonuses are available at these blackjack sites and whether or not blackjack applies toward the wagering requirements for these bonuses. Is online blackjack rigged? I've written about that as well. I also include information about what blackjack games are offered and what kind of house edge the games present to the player.
Please note that all of the information in this guide is intended to be used for entertainment or educational purposes only. And some jurisdictions have laws making online blackjack for real money. This site serves a worldwide audience, and the site also assumes that its visitors are responsible for knowing and obeying the appropriate laws in their area.
Don't ever gamble or play blackjack with money you can't afford to lose. Online blackjack is a negative expectation game, even if you're good at it and know basic strategy. It can be a lot of fun if you play with money you can afford to lose, but if you're looking for a way to make easy money, online blackjack sites aren't the place to look for that.
