🃏 Blackjack Rules

🎯 Objective

Get your hand value as close to 21 as possible without going over (busting). Beat the dealer's hand to win!

🃏 Card Values

• Number cards (2-10): Face value
• Face cards (J, Q, K): Worth 10 points
• Aces: Worth 11 or 1 (automatically adjusted to best value)

🎮 How to Play

• Hit: Take another card
• Stand: Keep your current hand
• Double Down: Double your bet, take exactly one more card, then stand

🏆 Winning Conditions

• Blackjack: 21 with your first two cards
• Win: Your hand beats dealer's without busting
• Push: Tie with dealer (automatically restarts)
• Bust: Hand exceeds 21 (you lose)

📚 Revision Twist

When you lose a hand, you'll answer math questions to continue playing. Get them right to maintain your score, or reveal answers with a small penalty. Double down losses require answering 2 questions!
