Pontoon is very similar to Blackjack as players are dealt 2 cards with the aim to reach 21 or secure a hand with 5 cards. Cards have the same value in Pontoon as they do in Blackjack. Ace can be either 1 or 11.
The two differ where players and the house must twist whilst they are on 15 or less and have less than 5 cards. You win by having the highest hand (no more than 21), having Pontoon (Same as Blackjack - two card 21) or with a five-card trick (Five cards in the hand and a value of no more than 21).
