YOUR SHOT: BEST
One of the best games on the floor when the rules are good — comparable to or better than a 6:5 blackjack table — but only if you use the correct, game-specific strategy. The edge swings on the rule set, so confirm dealer-hits-soft-17 vs. stands and whether redoubling is allowed.

✅ Best bet

The base game with the proper Spanish-21 strategy. It removes the four 10-spot cards from each deck (jokers stay), which sounds bad, but generous rules — late surrender, double-down rescue, player blackjack and player 21 always win, and bonus payouts on 7-7-7 and 6-7-8 — more than make up for it, landing the edge around 0.4–0.8% with the best rule sets.

🚫 Sucker bet to avoid

The Match the Dealer side bet (often 3%+), and playing Spanish 21 with ordinary blackjack strategy — the missing tens mean the correct plays differ, and using blackjack basic strategy here quietly costs you.

How the edge is computed

Removing the four tens raises the raw edge, but the player-favorable rules (player 21 and player blackjack always win, 5/6/7-card 21 bonuses, late surrender, double-after-split, double-down rescue) claw it back to roughly 0.40% with the best rules (dealer stands on soft 17, redoubling allowed) and up toward ~0.80% with dealer-hits-soft-17. Match the Dealer is a separate, much higher-edge side bet.

Optimal strategy

Learn the Spanish-21-specific basic strategy (it differs from blackjack because the tens are gone) and use the bonus rules — always take the double-down rescue and late surrender when correct. Skip the Match the Dealer side bet.
