WELCOME TO THE ALLEY.
BRING YOUR FRIENDS.
OKAY LET'S FIRST GET ACQUAINTED.
THE INSTRUCTIONS (Y/N)? THE GAME OF BOWLING TAKES MIND AND SKILL. DURING THE GAME
THE COMPUTER WILL KEEP SCORE. YOU MAY COMPETE WITH
OTHER PLAYERS[UP TO FOUR]. YOU WILL BE PLAYING TEN FRAMES.
ON THE PIN DIAGRAM 'O' MEANS THE PIN IS DOWN...'+' MEANS THE
PIN IS STANDING. AFTER THE GAME THE COMPUTER WILL SHOW YOUR
SCORES.
FIRST OF ALL...HOW MANY ARE PLAYING?
VERY GOOD...
