One rule set, clearly explained

These lessons use six decks, dealer hits soft 17 (H17), US peek, double after split, and no surrender. Doubling is allowed on the first two cards. Split aces get one card. The matching practice table pays blackjack 3:2. Other rules can change the correct choice; see the strategy chart and methodology.

Practice scores measure answers to these questions. They do not certify mastery or predict winnings. The trainer uses play money only; correct basic strategy does not remove the house edge in most standard games.
