Single Number for pilot 1.4 (1996/12/15)
by Yoshimitsu Kanai

<Introduction>
Single Number is a puzzle game for one player, specifically, one 
who is familiar with puzzle books or with the games found in the 
puzzle pages of weekly magazines. 
In this program, pilot shows puzzles which the player solves.

<Rules>
Numbers (1-9) are given in several cells in the 9x9 matrix. Decide 
the rest according to the following restrictions: "Each number (1-9) 
should appear only once in the 9 cells of each vertical line, horizontal 
line, and 3x3 matrix surrounded by the thicker boundary." 

<How to play>
There are two modes: user mode and book mode.
In user mode:
1. Select "New" from "Puzzle" menu.
2. Choose (1-9) number using push button below and fill the matrix.
(To correct the misinput, erase it using "clear" and input the right number.)
3. When all the cells are set with the correct numbers, the game is finished.

In book mode:
1. Puzzle will appear one after another.
2. Choose (1-9) number using push button below and fill the matrix.
(To correct the misinput, erase it using "clear" and input the right number.)
3. When all the cells are set with the correct numbers, the game is finished
    and next puzzle appears.
4. If you finished the Book, you can try ....(secret)....!

<Options>

In User mode,
2. Player can select 3 levels (beginner, intermediate, and expert).

       puzzle you are facing.)
