Spanish 21 and Pontoon are popular blackjack variations with unique rules. In Spanish 21, all 10-value cards are removed from the deck, increasing the house edge, but it offers favorable rules for players, such as player blackjacks always winning and bonuses for specific hands. Pontoon, a British version, has slightly different terminology—such as "twist" for hit and "stick" for stand—and both the dealer’s cards are dealt face-down.
