Pontoon is a card game akin to Blackjack, where players aim to get a hand value close to 21 without going over. Each player receives two cards and can choose to hit for more cards or stand. A unique hand called a "pontoon," made up of an ace and a ten-value card, triumphs over other hands. Players lose if they exceed 21 (bust), while the dealer plays with a requirement to hit until reaching at least 17. Winning can occur by having a superior hand, achieving a pontoon, or if the dealer busts. Game rules and payouts may vary, but the primary goal is to enhance one's hand while staying below 21.
