You start with 100 chips and choose a bet of 5, 10, 25, or 50. You and the dealer each get two cards, and your goal is to finish closer to 21 than the dealer without going over. Hit to draw another card, Stand to lock in your total, or Double to double your bet and take exactly one more card. Face cards count as 10, aces count as 1 or 11, and a two-card blackjack pays 3 to 2.
