What is the no-hole-card rule in blackjack?
In American blackjack the dealer peeks at a hidden hole card for blackjack before you play. Under the European no-hole-card rule, the dealer waits - and that small change means you can commit extra chips before finding out the dealer had 21 all along.
How it differs from the peek
In the standard American game, the dealer takes a face-down hole card and checks it for blackjack immediately. Under the no-hole-card rule used in European Blackjack, the dealer takes no second card until you finish, so you never know during your turn whether the dealer has blackjack.
Why it costs you extra
If you double or split and the dealer then reveals a blackjack, you can lose those additional bets too - not just your original wager. This adds roughly 0.1% to the house edge compared with a peek game.
How your strategy adapts
Because doubling and splitting are slightly riskier against a dealer Ace or 10, correct basic strategy for a no-hole-card game is a touch more cautious with those plays. Some casinos soften the rule with 'original bets only,' returning your extra chips. Try it on European Blackjack.

What is European blackjack?
European blackjack is a common two-deck game built around the no-hole-card rule: the dealer takes only one card until all players have acted. It also restricts doubling to hard totals of 9, 10 and 11 and usually forbids re-splitting. These tighter rules give it a slightly higher house edge than the American game.
When should you double down in blackjack?
Double down when the odds favor putting more money on one strong hand. The best spots are a hard 11 against almost any dealer card, a hard 10 when the dealer shows 9 or lower, and a hard 9 against a dealer 3 through 6. You get exactly one more card, so only double when a single card is likely to build a winner.
When should you split pairs in blackjack?
The two golden rules are: always split Aces and always split 8s, and never split 10s or 5s. Other pairs depend on the dealer's card - split 2s, 3s, 6s, 7s and 9s mainly when the dealer shows a weak card. Splitting turns a pair into two separate hands, each with its own bet.
