Bonfire: A Yin Yang birthday puzzle
(Eingestellt am 30. April 2026, 18:23 Uhr von Killer Joe)
Hello.
This was supposed to be a birthday puzzle, but it arrived fashionably late.
That just means the celebration lasts longer.
Normal sudoku rules apply.
Color the grid using two colors such that each color forms an orthogonally connected region and no 2x2 area consists of only one color.
Digits on a renban line form a set of non-repeating consecutive digits in any order.
Each line is divided by color such that both colors on a line have equal sums.
Have fun.

@deltameth: I have to disagree with you. How do you know what makes a difference to the “vast majority” and what doesn’t? And even if you did, why should we make life harder for some people just because it doesn’t bother others?
@Killer Joe: Please “worry about the critics.” If I’ve solved a puzzle with a pen and paper while lounging in a deck chair on my patio, why should I have to type in all the numbers just to get a solution code? Your reply to Wuschel sounds like you have a reason for this; I’d like to know what that reason is, because then it might be easier for me to understand your decision.
@StefanSch:I heard the critics and went back to normal solution code for future puzzles. I really did not expect this to be a problem. As you probably know I usually ask for row 9, first 6 digits. Very consistent, no matter if these digits are found early in the solve. I don't think people solve for the solution code but for the puzzle itself.
But this makes it very easy for trolls to brute force the solution code and down vote any puzzle without even solving it. That's why I thought it made sense to give the solution code in the end screen when you finish the puzzle through the only link available. The troll voting is bad behavior but down voting a puzzle for it's solution code isn't great either. We as setters put time and effort into this because we enjoy it and care about it enough to share with those who share that same interest. Together we can be part of a small community that inspires and motivates, or not...
Grts, Jonesy.
Thank you for the explanation. I'm sorry if the “downvoters” are getting on your nerves. But I'm not entirely sure I know what you mean. The vast majority of your puzzles have ratings above 90%. About 19 out of 20 of your puzzles are above 85%.
Most of my puzzles are below 80%...
If you think one line is too easy, then use two.

Wonderful puzzle!
I will strongly echo the sentiments that you should stick to normal solution codes.

This is a very interesting puzzle. Thank you for setting.
Don’t worry about the critics. Though the reasoning is correct it affects only on a very limited set of solvers. For vast majority it has absolutely no difference. People (me either) just don’t like when the routine is changed with no apparent reason. Routinely the expectation people on this site have is to list the digits in a row or column.

Great puzzle, thanks!

Brilliant puzzle! The low rating is just because of the way the solution code is presented, where I have to agree with the criticism. The puzzle itself is absolutely phenomenal. Thanks

forcing people to solve yin-yang puzzles is VERY BAD.

Forcing people to enter their solution in SudokuPad, just to get the solution code is verry bad.
What is the reason for such behavior?
