:There's another problem with the game code. 

 IF choice$ <> "YES" AND choice$ <> "Y" THEN ' and decides whether or not they want to play: 
 END IF 

  
 This statement does nothing. If they user enters YES or Y, the statement is false, and the game continues. If the answer is anything else, nothing happens, and the game continues. There ought to be an 'END' statement between IF and END IF. An even more graceful solution would be to wrap the IF ... END IF around the entire game.  

 However, when I altered this, it was reverted. It's a pretty basic (ha ha) mistake.
