For all the details please visit my page on Australian Pontoon. There are some rule changes in Australia, which merit a separate page. In Australia and Malaysia, Spanish 21 is called Pontoon. If you are looking for a change of pace from traditional blackjack but insist on a game with a low house edge, then you may find new excitement in Spanish 21. In locations where the dealer stands on a soft 17, or redoubling is allowed, Spanish 21 may be a better bet than blackjack, depending on the specific blackjack rules. Spanish 21 is a variation of blackjack, that in some cases is the best bet in the casino.
