Whether you call it Pontoon, 21, or an investment. Blackjack is easy to learn and even easier to play. The aim of Blackjack is to accumulate a winning hand of 21, or as close to 21, without going over (bust.) That’s all there is to it. No flushes, straights or trying to outsmart the other players, who, like you, are all just trying to beat the Blackjack dealer.
