Beat the dealer: get closer to 21 without going over. Face cards are 10, aces are 1 or 11, whichever helps.
Bet by tapping chips, then deal. You get two cards face up, the dealer one up and one down.
Hit takes another card. Stand keeps what you have. Double doubles your bet for exactly one more card. Split a pair into two hands, each with its own bet.
The dealer draws to 16 and stands on 17. A natural 21 (ace plus a ten) is blackjack and pays three to two. A tie is a push: your bet comes back.
The chips are only chips. Lose them all and the house hands you five hundred more. The book says is the standard play from basic strategy, if you want a nudge.
Sounds covers the card noises, and the slider next to it covers everything. Music plays soft ambient music. Night mode warms the screen for a dark room. Chill mode turns all three on for late nights. Every switch is remembered on this device.
