SDU-320

Introduction
SUDOKU is a fun game of numbers and logic
that anyone can play. The object of the game is
to place a number in every square of the 9 x 9
game board. But you can’t just fill in any
number anywhere. Each number from 1 to 9
can only occur once in every horizontal row,
vertical column, and 3 x 3 square. Each “level”,
or grid, begins with a few numbers already in
place. You simply have to use a process of
elimination to fill in the rest.
The first time you turn on your device, a
demonstration of the game is displayed. Note:
The demonstration also begins if no game is in
progress and no key is pressed for 10 seconds.
