PlayerGo #Draw the first two starting cards. Draw the first two starting cards (This can be done with a DrawCard Function) Display the cards drawn Work out the value of these cards (This can be done with a ReturnValue function) Display the value of these cards Repeat until player “Sticks” or is bust or scores a 5 card trick Ask if player wants to twist or stick Draw a new card if player “twists” (Using DrawCard) Work out new value of hand (Using ReturnValue) Check to see if you have bust (greater than 21) Work out the final score whether the player has bust or not
