Hit 21 is an interesting fast-paced Blackjack game where you use the cards to make as many 21's as possible within the 4 lanes. Select which of the 4 lanes you want to place the card. Make a 21 to clear the cards and earn points. Try not to Bust any of the lanes by going over 21. Use all of the cards and move onto the next round. Special bonus cards will make automatic matches. Make 21's within the bonus lane when it lights up to earn extra points.
