Play Blackjack Free Online. Place a bet between 1 and 200 credits and deal the cards. The object of the game is to get closer to 21 than the dealer without going over. After being dealt two cards, you can either Hit (Take a card), Stand (Don't take a card), or Double (Double Bet, and only take ONE card). If dealt a pair, you can split the cards and play two separate hands by doubling your bet. Blackjack offers the lowest house edge of any casino table game, but also requires the most decisions.
