Two More Basic Losses for the World’s Hardest

This post presents the review table, and basic traces of 46 and 188, two of the top rated ten puzzles of The World’s Hardest Sudoku Book. The puzzles were displayed on the last post.

These two don’t make it to Sysudoku Advanced.  If they did for you, you’re missing something about Sysudoku basic. Read the traces, taking in the traces page first if necessary.  Generate your own grid pictures. If you’re a beginner, the Guide coverage of Sysudoku Basic is there for you. There is absolutely no reason for me to have all the fun.

Basic on 46 is almost done when collapse begins, on the line marking of r6.

A near BUG is squashed at the end by a remote pair.









Worlds Hardest 186 is its second bypass casualty

Here is the review table for World’s Hardest Sudoku Book. When it can be put down, this is nothing like the review table of the world’s hardest is gonna look.  World’s Hardest is basic to advanced in difficulty, with only one selected puzzle, 200, bordering on extreme. That aside,  it’s hard enough to bring out some unusual moves.

Next week, the review closes with a walk through of puzzle 134. You don’t have to follow the review table entry, but it does show where I’m going, if you want to know.
