There are several variations of the game, some of them being standard 21 or European Blackjack, as well as Double Down, Split Double Up, etc. Some online real money casinos offer multiple variants, so it might seem confusing. Most importantly, should I split my hands? How much should I wager per hand?

What you get for playing total number of cards

If you are playing a Online Roulette Real Money that offers a single-deck blackjack variant, then you can be sure to get the best odds possible by betting $2 on all your cards (assuming you have an even number of total cards). This is because every time you hit, you will receive one more card than your opponent does. Since you always hold two cards when you play this variant of blackjack, you would receive only one extra card in the case of splitting your hand. Also, since the dealer has the advantage over the player, if you have a strong hand you’d want to avoid splitting, and vice versa.

You may also find yourself playing a variation of the game where you are dealt two decks

Decide about how to act with each one separately before deciding which deck you prefer. In these cases, it might be worth considering whether you should split your initial hand into separate hands for each deck. It depends entirely on your strategy: if you are trying to maximize the probability of hitting on your first turn, then you want to split your weak hand into two hands.

The House Edge

When playing many different variants of blackjack, you might not know what the house edge is until after you’ve played a few hands. At minimum, you should be able to figure out the expected value of your hand (i.e., the amount you expect to win or lose given your current position), but you should also consider the variance of your hand (i.e., the degree of randomness involved in winning or losing).

Conclusion

The expected value tells you exactly how likely you are to win or lose; variance is a measure of how much randomness is involved in making those bets. If you’re unsure about which way to bet, you can use the expected value to decide. If you can afford to lose more.
