Get a quick Sudoku fix on the iRex iLiad
In a world that has gone sudokuing mad, it doesn't come as a surprise that puzzle enthusiasts turn latest gadgets into platforms for ancient games. Thanks to MobileReader yokos who created 666 Sudoku puzzles of three different difficulties for the iRex iLiad. So, dear iLiad fans, it's time to sharpen your pencils... uhm, styluses!
How to play: Fill in the grid so that every row, every column and every 3x3 box contains the digits 19. There's no maths involved. You solve the puzzle with reasoning and logic.

One implies the other  but it's not necessarily the way around.

Easy explanation: It's not math in nonacademic understanding because you are not calculating to solve it.

It may be simple maths, but unless you're entering random numbers you'll still be doing some adding up, which still counts

Darn, i didnt want to cause so much confusion.
Just a little explanation. reasoning and logic are the basic principles of math. Calculation, is only a logic "framework", so you are basically using math every day and drrow, what do you mean? math => reason and logic but but not necessarily reason => logic => math ?? that might be true with alot of people.

How about this?... No advanced math needed, just simple arithmetic with integers. ;)

I'm not totally certain, but I'm wondering if a similar program exists for generating chess problems as does for the Sudoku puzzles?

The origins of Sudoku lie with the mathematician Euler who devised something nasty called Latin Squares.

Actually, those two games can not be compared. Usually sudoku games are created to have only one possible solution. You could design them to be more difficult with several solutions. But that would make it hard for the user, because he would come to a point in the game, where he has to "guess" a number for a field. I have yet to come across one of those. Until now i could solve every sudoku by just following plain logic without ever having more than one solution or even come across a dividing path while solving of which one would prove not solveable. It is for that an "easy" problem and can easily be solved by a computer in milliseconds. chess on the other hand is a multiplayer game, which offers a totally different level of difficulty. You simply can not calculate all possible moves and choose the best one there is in a reasonalbel amount of time. Thats why computers still loose against human beeings. There is a whole reasearch field about game theory and multiplayer game theory. Getting into that, that is high level logic, reasoning and calculation Math at its best.

It's either advanced or simple math depending on what strategy you approach the problem with, either way there is still maths involved

Oh, I see, Soduku doesn't even involve adding. I didn't realize that. I see why Alex said "no math!"
But if you do want some math, it's apparently all about combinatorics and permutation group theory. Here's one place to start learning about Soduku math... http://en.wikipedia.org/wiki/Mathematics_of_Sudoku And this is a cute article: The mathematics of Sudoku, a puzzle that boasts "No math required!".
