In Blackjack every hand requires a decision: stay or draw. Blackjack is played between the player and the dealer. The object being to draw cards with a value totalling 21, or as near as possible to 21 without going over the top, 'going bust' and losing. There are no big, roulette-style payouts, but by playing several boxes at once the wins can mount up fast.
