Spanish 21

Spanish 21 is a blackjack variant played with a 48-card Spanish deck (the tens removed) but offset by liberal player rules and bonus payouts. With optimal strategy the house edge can be as low as around 0.4%.

Quick facts

House Edge ~0.4%–0.8% by rules
Bonuses 21 always wins; 5/6/7-card 21 payouts

Fewer tens, more bonuses

Removing the four ten-pip cards from each suit hurts the player — tens help make blackjacks — so Spanish 21 compensates with generous rules: a player 21 always beats a dealer 21, players can double on any number of cards, late surrender is allowed, and bonus payouts reward five-, six- and seven-card 21s and specific suited combinations. Played with the correct (and more complex) strategy, the net edge is competitive with classic blackjack.
