A new variant see: http://forum.enjoysudoku.com/post257549.html#p257549 my first attempt is not too difficult - I'll improve it and post here. |

Really enjoyed this one, Hatman! Thanks! Printed out your V2 and the very difficult-looking 3. Will give those a go. (Am I wrong in thinking that a run-thru on these would be extremely long and difficult?) |

Thanks HATMAN! I found this new puzzle type quite tricky to get going, until I realized some implications of the puzzle rules which allowed me to think about it clearly. Here's how I did it after that. MeanDoku II - WT: |

Wellbeback My general approach to this puzzle type has been (I've been solving them in JSudoku.): enter 10(2) cages around all blue squares 1-9 run: clear 1 from reds, clear 9 from greens - solve out 23-78 run: clear 2 from two reds and 3 from three reds, clear 8 from 2 greens and 7 from 3 greens - solve out consider cells with red and green: cannot be too high or low consider nonets with almost all clues for interactions Maurice |

I only started trying MeanDoku NCs earlier this month, starting with the easiest one using the link in HATMAN's 30th May 2017 post, so I'm at least a year later than azpaull and wellbeback in trying them. This is a good puzzle for anyone who hasn't tried solving MeanDoku NCs before. Here is my walkthrough for the easier MeanDoku NC 2: |

Then I moved on to the harder version in this thread, which has fewer of the useful blue marks; one green mark has also been removed. For this it's almost certainly necessary to use the key feature of MeanDoku NCs, as pointed out at the start of wellbeback's walkthrough. I started my solving path using more routine steps, while wellbeback jumped straight in with the key feature and, at least in one place, got more from that than I did. Here is my walkthrough for MeanDoku 2H: |

Hi! This is David Nacin, author of the Meandoku being discussed here. I was really excited to find people in this forum trying out one of my Sudoku variants. I have to really thank Hatman before doing anything else for mentioning that it was tricky distinguishing the trapezoids in the original version I made for the MAA Focus. It never occurred to me to color in the trapezoids with different colors. Now I do that every single time, and my meandoku are much clearer because of it. Thanks! I wanted to toss out a few more places where you can find Meandoku in case anyone wanted to try some more. There's another Meandoku at my blog:https://quadratablog.blogspot.com/2018/08/meandoku.html And a Meandoku was posted as part of a contest on Twitter: https://twitter.com/wpunj_edu/status/11 ... 3987743752 (Just ignore the article, the puzzle is below.) I might post a few other of my Sudoku variants in the variants section here, and I'm looking forward to trying the Meandoku that Hatman made and posted as well! |

Welcome David I've really enjoyed making these so please post any other puzzle ideas you have. When I first saw your meandoku, I though "this just a small variation", however it gives very interesting and different to solve puzzles. Please try my ORCs and Triankles. Maurice |

I'll second the welcome, David! You'll find this forum has a very friendly bunch of like-mindeds, and I do hope you'll become a regular. (There are also the non-puzzle-makers like me who enjoy trying the challenges creators like you post here!) I've really enjoyed the Meandoku variant, and will check out your links. --Paul |
