Post Error in The Best Brain Exercise Puzzle Book
On Logic Puzzle 67 it appears that "Jane Doe's house has a higher address number than the Doans' house" is violated by the solution in the back of the book.

Or am I missing something?

No, it does look incorrect [sad]

I'll check with Phil (he created all the logic puzzles).

I checked, and this is his reply:

"The only way to correct it is to change "Doan's house" in clue 3 to "Carl Smith's house," and add "and the Doans don't live at 408 Oak" at the end of clue 5."

Does that fix it?

I'll update the book so new puzzlers get the corrected edition.

Also, which logic puzzles did you solve so far?
(just to be able to limit any extra checking [smile] )

Puzzle 67 is as far as I have gotten into the book. No other problems so far, but I haven't gotten a chance to see if the fix works.

Ok, thanks. There may be one other logic puzzle which needs a minor fix, I'll keep you posted.
(puzzle 144, "Scheduling for the Fall Semester")

(and of course, once confirmed, the book will be updated, I'll add the info to https://www.calcudoku.org/bbe,
and will send updated puzzles to everyone who has submitted a solution from the book so far).

This has been done now.

The version on Amazon should be updated shortly as well.
