With diagonals that must also be matched and a secret"magic puzzle heart" hidden inside a spruced-up grid.

Let me introduce the rules of this SuperSudoku game:
The aim is to enter a numeral from 1 to9 in each cell of a 9X9 grid made up of 3X3 boxes, starting with various numerals given in some cells.
Each number in the solution occurs only once in each row, column box and two diagonals.
Completing the puzzle requires no special maths, just patience and logical reasoning.Of course, there are differnet difficulty levels.

And if you're curious enough for a little history of Sudoku's, read on...

"Sudoku's origins date back to 1979 when the first puzzle appeared in Dell Magazine's Math Puzzles and Logic Problems under the title Number Place. THe puzzle was later introduced in Japan in 1984 and given the name Sudoku (su = number, doku = single). In 1997, a New Zealander by the name of Wayne Gould discovered a few Japanese sudoku puzzles and spent the next six years writing a computer program to produce them. He began sending his computer-generated sudoku puzzles to the British newspaper The Times, which first started putting his puzzles in their newspaper in November 2004."

Info is from The Mammoth Book of Sudoku. Nathan Haselbauer wrote the introduction (above).
