Complete Alternative Strategy for Solving Sudoku.
Totally Unique and Distinctive Approach.

For Beginners, Intermediates or Advanced Sudoku Enthusiasts


Just Four Simple Steps and you can solve any Sudoku.
No messy Possiblity Matrix to deal with. Forget the X-Wing, the XYZ-Wing, the Jellyfish and the Death Blossom. Build your Solution as you go!

Pre-Publication Special: PDF-Only: $24.95



Beginners (Sudoku-ka)

Start learning the RIGHT way. Once you understand a couple of simple procedures, you are on your way to solving Sudoku rationally and completely. Unlike those who have learned the standard strategy, you will have nothing to unlearn. The system is a reflection of how you actually solve Sudoku... unlike the standard strategy which creates an artificial structure which is confusing and time consuming (and, I might add, highly impractical). With Rational Sudoku, you apply a few simple rules and some mental gymnastics and you have your solution.

Intermediates (Sudoku-san)
Switching to Rational Sudoku could never be easier. You are already using many of the procedures, but Rational Sudoku provides you with a new structure with which to solve them. The nomenclature is clear and intuitive; the steps are rational and understandable. No more messy possibility matrices; just straight-forward, logical and rational steps to solving every Sudoku.

Advanced (Sudoku-sensai)
It is all about Discovery! Discovering a new strategy is what Sudoku-sensai live for. Here is an entirely new procedure that might just drive you into ecstasy. Not just another little wing-ding, but an entirely new strategy for solving Sudoku. While old habits are hard to break, the challenge comes in understanding the new strategy in the context of the old. None are as prepared for the appreciation of the beauty and elegance of Rational Sudoku than you!

US Sudoku National Championship



Greetings from Philadelphia. I just competed in the first ever historic US Sudoku National Championship competetion. I came up here to test my strategy against real people (nothing against WebSudoku) and find out once and for all if it worked. What a Surprise! Not only does this Rational Sudoku Strategy work, but most of the winning contestants use some form of this system. In fact, there was not a single finalist that used the 'Possibility Matrix' system! The winner of the competetion, Thomas Schneider, in fact, uses a strategy almost identical to Rational Sudoku, but with modified notation. There were many 'Possibility Matrix' contestants at the competition, but none of them made it to the finals. Neither did I, but the three finalists in the Advanced group (out of 150 contestants in the advanced group) all used some form of Rational Sudoku and certainly did not use the 'Possibility Matrix'. When you consider that Thomas finished his finalist Sudoku in a mere 7 minutes and 7 seconds, you might realize that you would barely have time to create a 'Possibility Matrix', much less begin extracting solutions from it before the competetion was over. Congradulations to Thomas! He is one heck of a nice guy. At 27 he has been solving Sudoku since he was about 9...even before it made its debut in Japan. Obviously, there was some stiff competetion, including other World Championship Sudoku contestants. Overall it was a great experience and very gratifying to see that all the work I have done has been in the right direction.Well, I have to go catch a plane back to Atlanta, but I will have more on the US Sudoku National Championship later...including the Finalist puzzle and a Rational Sudoku solution for it!Sudoku SamRatadu Sudoku!PS. For more direct reorting on the Sudoku National Championship visit the Philadelphia Inquirer at www.philly.com. They were the ones who sponsored the competetion and they will have lots to report on it.Labels: travels

..........So why a new solution strategy for Sudoku? Especially for beginers... have you ever felt just totally overwhelmed while trying to carve a solution out of a possibility matrix? Ever think that this is more complicated than the original Sudoku? Now, with just four simple steps, you can solve any Sudoku! No more Possibility Matrix! You BUILD your SOLUTION as you go! This streamlines the process and avoids the confusion of the extraneous digits of the Possibility Matrix. You can even solve Sudoku without using any marginal notes at all! It is really not that hard once you get the hang of it.For intermediates... are you yearning for a way to streamline your solution process? Rational Sudoku is your answer. Have you finally figured out that the Possibility Matrix is just a clever marketing tool for generating endless 'strategies' that can be documented and sold? Have you already abandoned this tiresome strategy and just winging it like so many have done? Don't you wish someone would figure out a better way of solving Sudoku? Well some one has! Rational Sudoku does away with the X-Wing, the Jelly Fish and the Death Blossom and all the rest of those colorfully named 'strategies'. All you need are four basic operators and you can solve any Sudoku!And for the advanced...so now you think you know it all? You can spot those naked pairs in a jiff; smoke those death blossoms with ease; and finish off the Sashimi Finned X-Wing for dessert. Could anything be better? Well how about something completely different? A strategy so radical that no one has ever concieved of it before now. Something so simple and elegant that you will wonder why you haven't seen it before. Are you up to the challenge? Can you really handle something that will bend your Sudoku twisted mind in ways you never thought possible? Rational Sudoku will change the way you think about Sudoku! Its your call.Sudoku SamLabels: Why a New Sudoku Strategy?
