#   This program plays the Take Away Game. A game where you have 21 chips and need to remove all of them to win.
#   You specify the amount of rounds you want to play and you play those rounds. 
#   To take away a chip, you input a number between 1 and 3 and that many chips will be removed.
#   There is a second player however so once you take away some chips, the other player can take away chips as well.
#   The first person to finish removing all of the chips wins.

#   This program has a logical structure and well named variable names so it is easier to understand

#   The top paragrapgh explains the base game but I added additions to the game such as multiple players and a final scoreboard at the end.
