A blackjack beats any hand that is not a blackjack, even one with a value of 21. Wins are paid out at even money, except for player blackjacks, which are traditionally paid out at 3 to 2 odds. Many casinos today pay blackjacks at less than 3:2.
Blackjack usually pays out immediately. Winning bets are paid even money, meaning you're paid 1:1 on your wager. A 3:2 payout is typically given when you're dealt a natural blackjack. Whether taking even money is the right play is a matter of opinion.
The Lock It Link feature is a free spins bonus where adjacent designated symbols on the reels will be linked together and locked in place. Throughout the free spins, each designated symbol landed will remain locked in position, display a credit or jackpot value, and additional spins will be awarded.
