When playing blackjack, the house always has the advantage. That being said, there are a variety of strategies that can be used to try and beat the dealer.
In general, the bet size for blackjack is about 1/3 of the bet size for roulette. That means that a bet of $5 on blackjack would be equivalent to making a $2 wager on roulette.
When playing blackjack, it is important to understand how to count cards. In general, aces are worth 1 point, 2s through 10s are worth face value, and a king (10) is worth two points.
When counting cards, it is important to keep track of both the face value and point value of each card. This will help you determine whether or not to make a bet.
Overall, blackjack pays about 2-3 percent less than roulette. This means that for every $100 wagered on blackjack, $102 would be returned in winnings.
As long as you understand how to count cards and make sound betting decisions, blackjack can be a profitable game of casino gambling.
