What is SUDOKU?
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.
This device stores 99 levels in increasing levels of difficulty. Levels
1-20 are for beginners, 21-70 for intermediate players, and 71-99
for advanced players.
