At the start of the game the program keeps a random number between 1 and 100. It shows one greater and one less than this number as a clue. For example, if the number you need to know is 76, it might say between 24 and 97 as a hint. Remember, it can give you the number you need to know as a clue. You need to know the number for all 5 guesses. If you do not know the number in all 5 guesses, your game is over. If you know the number correctly, you will earn points as much as your hint range. For example, if the number you need to know is 52 and your clues are 25 - 75 when you know the number, you will earn 50 points.
