Sudoku and Symbol Sudoku
The word Sudoku simply means "single number" in Japanese. A sudoku grid contains 9 large squares; each large square contains 9 squares for the placement of a single number.
The numbers used are between one and nine, including one and nine, and there is no mathematical relationship between the numbers.
In 1979 freelance puzzle constructor Howard Garnes introduced the game, which he called Number Place.
In 1986 in Japan two important changes were made that led the popular game as we know it today. First, no more than 30 numbers were given in any puzzle grid to help a solver. Second, the puzzles were symmetrical.
This is an example of a plain sudoku.
Symbol Sudoku
Symbol sudoku puzzles created by Punzhu Puzzles add an extra degree of challenge for solvers. Instead of the numbers 1-9, Punzhu uses various symbols. Many of our symbol sudoku puzzles have a common theme to their symbols.
Here is one example of the various symbols used by Punzhu Puzzles in creating our very challenging symbol sudoku puzzles using Unicode box drawing style of symbols:
Both sudoku and symbol sudoku puzzles are available for free on our web site. Punzhu Puzzles has also created special symbol sudoku puzzles for businesses and educators. For more information on our commercial sudoku puzzles contact our sales department.
