Systematic Sudoku, or Sysudoku, is a blog about humanly practical techniques for solving Sudoku puzzles. The blog consists of weekly posts and a set of supporting pages, accessed by a menu bar. Sysudoku offers an efficient and systematic approach to Sudoku, with completely documented and visually supported solutions.
Blog posts are released Tuesdays at 2 p.m. EST. Most current posts detail the solutions of difficult puzzles as a way of rating and reviewing published collections. A good way to get an overview is to look over the Titles page, and other support pages. To get to a post by date, scan the monthly archive list on the right margin, and click on your date and title in the month archive.
Besides Titles, there is a glossary called Sysudoku Speak, a Tools page describing ©PowerPoint and ©Word blog templates, and summaries of conventions used in review tables and traces.
Those few that are interested in early development of Sysudoku can work through the posts from the beginning in September 2011. For everyone else, there’s the Guide, an illustrated manual that explains Sudoku for beginners, and Sysudoku principles and rationale for others. The Guide is a set of linked menu pages. Click on the menu bar Guide link for the Guide page itself. Drag to the right side of any parent page for the menu of links to child pages.
All illustrated examples are taken from puzzles selected for collection reviews and instructive books and sites, under “fair use” guidelines. Two computer solvers, the Sudokuwiki solver freely available on Andrew Stuart’s sudokuwiki web site, and Philip Beeby’s philsfolly, are used occasionally with acknowledgement, for the sake of accuracy and meeting weekly deadlines. The solver’s results are not the basis for human solving advice or collection ratings offered on Sysudoku.
Comments are welcome and complements appreciated, but only those judged to be helpful to Sysudoku readers are published and answered. Please comment on the relevant post.
