Puzzle Description:

The riddle goes like this: What do you throw out when you want to use it, but take in when you don't want to use it? An anchor on a boat.

No guessing required. Edge logic on the C1 and R1 make the rest of the puzzle easy to solve.

Quite right, Teresa!

Why is it when I do edge logic I always seem to start 'guessing' at the wrong end...sigh.

Great puzzle. Ditto #1.

In Re: #3, when I first started learning to use edge logic, I would always just start in the upper left corner and randomly try any and/or all edges until I found one that worked. As I have gotten better at edge logic, I can start to see places that it will work. Quickly glancing at the first 2 columns here, for example, you see them ending in a 4 and a 1. That practically screams edge logic. Now quickly glancing at the first clues of all the bottom rows, you can see that the 4 can't go anywhere down there because they are all > 1, and so on.

In fact, after reading these comments, I went back and tried starting over and using edge logic everywhere else and I couldn't get anything.

Found to be logically solvable by Gator.

#4 - you can use some edge logic (and deep edge logic) with the 5 clues in row 20 and column 20, but it would be utterly pointless, as you mentioned, because of the 4 clues that are practically screaming at you. Nice puzzle.

I used some deep edge logic with the 8s, and that was kinda cool. Nice riddle, Teresa. ^_^

I wish the clues would stop screaming at us. :(
