Blackjack like all other card games is constantly evolving, so there are quite a few variations of it out there. Here are some of them.
21st Century Blackjack – Player doesn’t automatically lose if he busts. If the dealer busts as well, it’s a push (sometimes he has to also bust with a higher total).
Double Attack Blackjack – Blackjack only pays even money and the player has the option to increase his bet after seeing the dealer’s cards.
Double Exposure Blackjack – Both of the dealer’s cards are dealt out face up. The player loses if it’s a tie. Blackjack pays out 1:1 for even money.
Switch Blackjack – The player plays with two hands and can switch one card between the two hands. Blackjack pays out 1:1 and if a dealer gets 22 it’s a push instead of a dealer bust.
Multiple Action Blackjack – The only real difference is that the dealer gets more than one hand, so the player pays multiple bets and plays his hand individually against each of the dealer’s hands.
Super Fun 21 – The player can split more often (up to 4 times). If a player has six cards with a combined value of 20 he automatically wins the hand.
