Trifecta Costs\n\n This bet is like the Exacta but with one extra horse, so a basic Trifecta means selecting three horses in a race to finish first, second and third in the exact order. As there is one combination involved here, a $2 Exacta would cost a total of $2 but there is the option of placing a Trifecta Key.

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.

A basic betting strategy is simply to double the bet after losing a hand, also known as the Martingale system. This can go for multiple hands in a row until you win at blackjack.

Blackjack naturally has a mathematical percentage that favors the house, although the payout percentage varies by the skill level of the blackjack player. Online games use random number generators (RNGs) to ensure their odds match the payout of land-based casinos.
