In the simplest version of the Black Jack online, you play against the dealer. Cards use random number generator software for dealing. You “sit” at a table after buying chips, place bets, and then are dealt a hand. Decisions are made by clicking buttons. Messages pop up on your screen throughout the game, if you make bad moves, or you win. Always play at regulated and credible online casinos, so your money is safe. They will credit the payouts to your account automatically, should you win.
