Rules (project-specific)

Basics

• The goal is to get a higher total than the dealer without going over 21.
• Number cards are their value, J/Q/K are worth 10, A is worth 1 or 11.
• Starting bankroll is $1000.

Dealer behavior

• Hits on totals under 17.
• Also hits on soft 17 (A counted as 11 for a total of 17).
• Keeps the first card face-down during the player's turn.

Outcomes and payouts

• Blackjack (21 with the first two cards) pays 3:2.
• Ties are a push.
• Player bust is an immediate loss.

Available / unavailable actions

• Double down: available (first two cards only, if you have enough bankroll).
• Split: not available.
• Surrender: not available.
• Insurance: not available.

Deck

• Single 52-card deck.
• Automatically switches to a fresh deck and shuffles when fewer than 13 cards remain.

Notes for play

• You cannot start a round with a $0 bet.
• If your bankroll reaches $0, you get "Game Over" and can r to reset or q to quit.
