Quick answerGet closer to 21 than the dealer without going over. Place a bet. You get two cards; the dealer shows one.

Some decisions

Five steps

  1. Place a bet.
  2. You get two cards; the dealer shows one.
  3. Hit to take a card, stand to stop, double to double your bet for one card, split a pair.
  4. Go over 21 and you lose at once.
  5. The dealer draws to 17; the higher hand wins.

What it pays

OutcomePays
Blackjack: an ace and a ten-value card3 to 2
Beat the dealer1 to 1
Same total as the dealerStake returned
Insurance, if the dealer has blackjack2 to 1; avoid

A sample round

You bet £1 and are dealt a ten and a six: sixteen. The dealer shows a nine. Basic strategy says hit, so you take a card: a four, making twenty. You stand. The dealer turns over a seven for sixteen, must draw, and gets an eight: bust. You win £1.

A good first bet

Stand on 17 or more; hit 12 to 16 when the dealer shows 7 or higher; always split aces and eights; never take insurance.

The mistake to avoid

Playing at a table that pays 6 to 5 for blackjack instead of 3 to 2, and taking side bets.

What it costs

With basic strategy and good rules the house keeps about 0.5%: about 50p per £100 staked.

Before you play: set a deposit limit, decide a budget, try the demo, follow the six steps.
