Puzzle Description:

Is this possible to solve? Well, if you are reading this congratulations! You did it! another fractal let me now if it possible to solve

#1: CB Paul (cbpaul) on Dec 2, 2020 [HINT]

I like it! I saw the pattern. The logic breaks only once, at the very end - or beginning, depending on how you look at it.
#2: Kristen Vognild (kristen) on Dec 2, 2020 [HINT] [SPOILER]
There are multiple solutions for the 9 squares in the top left corner. The rest is simple enough to figure out, using color logic and established patterns, once you reach the smaller shapes. For example, the blue squares in R14 C15 and R15 C14 could also be placed in R14 C14 and R15 C15. Same with the two greens, farther up, and the two reds beyond those.

Also, Jan is, sadly, several years beyond being able to solve this.

Found to require some guessing by kristen.

Yup, those 9 squares top-left is where the logic breaks, too - at least the way I solved it.

Actually, the logic breaks only in the very top-left square. Squares R2C3 and R3C2 are consistent with the progression of the rest of the forms.

You can probably tell that I started bottom-right. I don't see how to start elsewhere.

Agree. It is easy to solve. It is easy to spot the pattern and solve it. I did have to guess in top left corner, but after three tries, I got it. I certainly wouldn’t rate it difficult.

Found to have multiple solutions by lollipop.
#7: Lollipop (lollipop) on Dec 3, 2020
As Kristen noted at #2, working from the bottom right diagonally upward toward the top left, there begin to be multiple solutions starting with the topmost black/red/green/blue combo and continuing upward. It's not solvable without guessing.

Darren, please change your title. It's not your fault for not knowing, but it's hurtful for those of us who remember our much-loved Jan. It's Jan's partner Valerie who has continued to run the site, for which we are so grateful.

Lollipop - I am curious how you set the puzzle to have multiple solutions in #6. I don't think that should have been possible?

Me personally, the title of this puzzle doesn't bother me. But if it bothers other people, and from your comment it sounds like it does, then I'd be glad to see it changed.

Thanks for the kind words. I too am glad that this site is still here!

Glad the title didn't bother you Valerie. I was wondering how others would take it. For me, I enjoy being reminded of Jan. Bittersweet.

David - I too am glad to be reminded of Jan.

In a few weeks it will be six years since he died. I know he would be pleased that people are still enjoying WebPBN.

I'm always happy to be reminded of Jan, who remains with us in spirit. It was the title's dare, the gotcha, that hit me.

Valerie, I have no idea how I came to set the puzzle to have multiple solutions (which it does, and not just in the top nine squares). The choice came up after I solved it so I selected it. I was as surprised as you were when the robot posted it.

When there is a puzzle that the automatic solver can't get a handle on, it leaves both determinations open. If someone finds a correct solution that is not the intended solution, the robot then marks the puzzle as multiple solutions, and credits the person who found the solution.

Thanks Joe!
