This is a 4 part series getting increasingly difficult in solutions. None are hard. My purpose is to help new puzzle creators and those that rate puzzles to understand them, how they are made and how they are solved. If you have any questions, please ask.

yeah, I have a question...


is there any direct correlation between the amt of puzz's you just published in a 24 hr period and the # of Old Styles consumed in said 24 hr period?

hey, you said to ask a question... ;) hahaha

Close, Kurt. Not really. Received some bad news, couldn't sleep.

This puzzle is entirely line logic solvable.
when you use the helper or control L, it doesn't recognize that either side of a 1 in a clue has to be dotted. If you need help, ask for it, please. This puzzle is much easier than #4 in this series.

Sorry to hear it, buddy. Hope everything's alright...

Tom, you might wanna solve this again...I didn't solve the first time when posting a comment cuz I figured it was prob gonna be too easy. Maybe I missed something, but I'm not seeing it as LLS.

actually, I'd like to hear what infrapink or one of that ilk have to say about it..

Kurt, I used the helper function when designing puzzles. Makes it quicker and I can post a gazillion in a day. Perhaps you are missing the 2 in c4. Before it is filled in, there is a single space that can only be white. It totally solves with line logic, but when I have a minute I will solve it without the helper.

Just solved it LLS without using the helper. Don't know where you're stuck. Pretty straight forward. I always think about the edge, but curtailed it (or should I say Kurt-tailed it), and did't cave. Not to Gator's difficult LLS solve, but it worked for me.

whatever the 2 in c4 means to you, I'm not seeing it. too bad I can't show you what my grid looks like...but as far as ll goes, c4 has dots in r1,11-18. the 2 in c3 is placed. c5 has dots in r's 1-4, 5-8 open yet and the rest of the c filled in.

put that into your grid and tell me how and why you can do any more in c4 by line logic alone. (you can't place a dot beside either black in r5c6 or r5c8 yet--you only know r5c8 is part of the 4 clue, but not exactly where the 1 in r5 lies)

it'd solve easily with a dot by either black in r5, and I think you might have put one there.

Think you are correct. I must've morphed it. Been looking for that elusive pixel for the last hour and couldn't find it.

Not sure if some of this is considered guessing.
At the point where LL end EL end:
1) 2-way logic makes C17R1-5 blank.
2) a little more EL in R1
3) if R2C8 is blank (or dot if you prefer), that directly leads to both R8C6 and R8C8 being black, which they cannot be. Therefore, R2C8 must be black.
4) if R5C5 is black, then in 4-6 moves, you get a contradiction in C4R5-7. Therefore, R5C5 is blank.
5) LL finishes.

Not sure if my steps 1-3 are necessary. I’m pretty sure my step 4 is considered guessing, but I don’t know if there’s an easier way.

Found to be solvable with moderate lookahead by dbouldin.

i did the same first two steps as bill, then did this:

- C9R5 and C9R6 can't both be dots or it violates C5, so C9R1-4,8 are dots
- C5R8 and C7R8 can't both be dots or it violates R6, so C1,2,17,18R8 are dots

LL to finish
