# Modified to read the word list from a file
# Reads a score.txt file with the number of hits per player
# Reads a words.txt file with the list of words
#
# Before running:
#
# Create an empty file named score.txt
# Create a words file named words.txt
# containing one word per line.
#
# The game randomly chooses a word from this file
