Sudoku Puzzles - Electronic Games
(Su Doku) is a logic based placement puzzle, sometimes referred to as Number
Place in the United States and Canada.
The aim of the puzzle is to enter a numeral from 1 through 9 in each cell of
a 9×9 grid made up of 3×3 sub-grids - called "regions", starting with various
numerals given in some cells - the "givens". Each row, column and region must
contain only one instance of each numeral. Solving the puzzle requires patience
and logic. Its grid layout will remind you of other newspaper puzzles like
crosswords and chess problems.
Sudoku puzzles do not require any knowledge of mathematics to solve.

for the cells. Some children's games use animals.
