A brand-new, relatively easy way to solve sudoku puzzles.
This advanced textbook follows the Subpattern Analysis Textbook, and should not be attempted until the earlier one has been assimilated. Patterns are studied separately by group, determined by the number of subscripts, and are further differentiated by pattern code, which is an attempt to create a unique picture code for every pattern.
14 fully solved problems in subpattern analysis, step-by-step, from initial pattern analysis to ensuing subpattern solution. Intended as further practice in subpattern analysis. A useful adjunct to The Secret Power of Subpatterns.
43 problems and solutions in the identification of killer candidates as a by-product of subpattern analysis. Intended as further practice of the principles laid down in The Secret Power of Subpatterns.
64 problems and solutions in the recognition of and use of n-wings in the reduction of candidates prior to the use of subpattern analysis, as presented in The Secret Power of Subpatterns.
120 problems and solutions in the science of analyzing digit patterns. A necessary adjunct to The Secret Power of Subpatterns.
72 problems and solutions in the use of the polarity principle, an adjunct to N-wings in the reduction of candidates prior to subpattern analysis. Intended as a companion to The Secret Power of Subpatterns.
500 problems and solutions, presented in a step-by-step fashion, illustrating the most important and basic technique in modern-day sudoku solving, and vital to the testing of subpatterns using temporary updates. Intended as a companion to The Secret Power of Subpatterns.
A radically new method of solving sudokus, which, when coupled with N-wings and other single-candidate solving techniques, offers a unitary approach to solving many of the hardest sudokus in many cases in less than half the time.
