You sit down to play one of your favorite games at an online casino and they you wonder — hey, how does this game really work? Not what are the rules or where do I place my bet but — how does the computer make playing blackjack like playing with a deck of cards? After all, if you’re playing with your online casino real money, you want to know what’s going on.
Now, people seem to worry about this less with slots, which is interesting because online slots and casino slots all are pretty much computer run these days. I think people often just have less trust over slot games in general, though they do have to follow fairly strict rules. But when it comes to card games, players start wondering how the computer program makes “cards” because it’s obvious there isn’t a little man hiding in there with a deck of cards.
This casino magic is all done with a little program called an RNG or Random Number Generator. Now programming an RNG to be truly random and making sure it is properly tested is part of what goes into making a casino a fair play casino. But if you want to quickly understand how an RNG works, try this. Write the numbers 1 through 52 on slips of paper. Now associate each number with a specific card in a card deck. Say 1 might be the Ace of Spades and 2 the deuce, and so on. Now instead of dealing cards, draw the numbers from a hat and use them to arrange the hands. The results really should mimic the results of a well shuffled deck. In fact an RNG probably shuffles even better.
Ready to deal another hand? You just toss the numbers you’ve already used back into the hat and draw again. Now this little detail is important to blackjack players because it’s why card counting doesn’t work online. Every single hand starts with the same 52 cards and the previous hands have no effect on it. Basic strategy works with an RNG, but card counting doesn’t. Which is why it is important to know how those casino games work.
