About
A clean table game of twenty-one dealt from a four-deck shoe. Hit, stand or double down with the keypad, the dealer draws to 17, and a natural 21 pays 3 to 2. Start with 100 chips; reach 1000 to beat the house, or go broke trying. Your best peak bankroll is saved. Splitting and insurance are not included to keep the game simple on small screens.
Objective: Grow your bankroll from 100 to 1000 chips.
