Game A is a blackjack game. The dealer's hand is on the upper screen and the player's hand is on the bottom screen. Four buttons are available: double down, bet ×10/hit, bet ×1/stand and enter. The player starts with a $500 bankroll and can bet up to $100 each hand. Pair splitting is not allowed, and bets must be locked before shuffling is done, contrary to real-world blackjack rules.
