While online gambling and sports betting is prohibited in California, there are alternative options available for those wishing to play online casino games. There are numerous social and sweepstakes casinos such as High 5 Casino and WOW Vegas offering online slots, table games, card games and progressive jackpots.

While online gambling is illegal in California, the same can't be said about Nevada. Online gambling in Nevada is legal and regulated by the Nevada Gaming Control Board. Online gambling is available in Nevada through licensed operators.

For the 21+3 side bet, a player will win if the two face-up cards and the dealer's face-up card include: 5:1: Flush with non-numerical sequence cards same suit. 10:1: Straight with 3 cards in numerical sequence other suits. 30:1: Three of a Kind, 3 identical cards, other suits.

Top 3 is a second optional proposition wager with 21+3, where you can receive large payouts on a three of a kind, a straight flush, and three of a kind suited. See posted paytable for payouts and minimum/maximum betting limits. Top 3, just like 21+3, has no effect on your main blackjack bet.
