+RULES OF THE GAME:
+
+1. The goal of the game is to add up your cards to the largest number without going over 21.
+
+2. If the cards in your hand add up to more than 21, then it's called a bust. It means that you lose immediately.
+
+3. All the cards from 2 to 10 count as their face value.
+
+4. Jack, Queen and King each count as 10.
+
+5. Ace is a special card. The Ace can either count as a one towards your total, or it can count as an 11.
+
+6. Depending on whether, if you've gone over 21 or whether if you're under 21, you can decide which value you want your Ace to represent.
