How to play blackjack

Blackjack in five steps, with a first round walked through.

Key takeaways

  • Best bet: a 3 to 2 table, played with basic strategy.
  • House edge: around 0.5%.
  • Avoid: insurance, side bets and 6 to 5 tables.
  • Start at the lowest stake.

AnswerYou and the dealer each try to get closer to 21 without going over. It is the one common casino game where your decisions change the price.

The rules in five steps

  1. Place a bet.
  2. You and the dealer receive two cards; one of the dealer's is face up.
  3. Hit, stand, double or split.
  4. The dealer draws to 17.
  5. Closer to 21 wins; blackjack pays 3 to 2.

Your first round

You bet £1 and receive a ten and a six: sixteen. The dealer shows a seven. Basic strategy says hit, because the dealer probably has seventeen. You draw a four: twenty. You stand. The dealer turns over a ten for seventeen and you win £1. Had the dealer shown a five instead, you would have stood on sixteen and let the dealer risk busting.
