Super Fun 21 Super Fun 21 is a variation of blackjack. The game is played using a standard 52 card deck. Aces can be counted as either a one or eleven depending on which value would best benefit the player's hand. All the face cards in the deck each count as ten. The remaining cards are taken at face value. The player must first place a bet and is then dealt two cards face up. The dealer is dealt two cards as well, but one is face up and one face down. The player then has the option to either "hit", (request another card) or "stand" (decline additional cards). The player's hand must beat the dealer's by coming closer to 21 without "busting" (exceeding 21). A winning hand with a total of 21 is called a blackjack, or natural.
