Alary at His Stingiest

This post details the solving of the Antoine Alary review puzzle More Extreme 104, featuring a laborious line marking leading to a sea of candidates. Then the day is saved by Antoine’s escape hatch, maintaining a reasonably advanced level of the collection.

The bypass has some success, but Whew! The 2-D trace of line marking doesn’t remotely do justice to the effort involved.

If you aren’t convinced, here are some line marking pointers: Go back through it, and this time, form the next long line string from the previous one, by deleting the new clue numbers, and typing back in the old ones. On really long strings (6f, 7f!, 8f!!), after copying the line string, delete the numbers seen from the cell before inserting the copy into the cell.

Oh, you’re doing this by hand? You’re not using my ©PowerPoint template? No wonder you’re thinking of tossing Alary’s book into the round file. Don’t do it, Pilgrim! Look at the Tools page. Send the email. Get the template file, it’s free. You can thank me later.

The collapse continues without hesitation, undeterred by the large number of candidates in many cells.
