Blackjack Strategy Quiz

Ten questions a level on blackjack plays, odds and rule changes. Every answer is calculated, every wrong answer is explained, and levels unlock as you score.

Level 1 · Question 1 of 10

You hold 10 and 6. The dealer shows a 7. What is the best play?

The quiz needs JavaScript to deal questions. The answer here is hit: against a 7 the dealer usually makes 17 or better. The strategy chart works without JavaScript.

What the maths says

Strategy answers come from the same engine as the strategy chart: the expected value of every legal play, for six decks with the dealer standing on soft 17. Level 1 only uses spots where the best play beats the next best by at least 12 units per 100 bet; level 2 uses spots where the gap is under 6 units, which is where most players slip.

Odds questions are calculated too: dealer bust rates and bust chances from the engine, side-bet and baccarat edges from exact enumeration, and rule effects from the published Wizard of Odds table. With perfect play under these rules the house still keeps 0.33%.
