Post subject: | Bloomdoku, Torn-Bloomdoku & Ninjutsudoku |
These were once posted on the now vanished DJApe forum. I don't want to mention that name anymore. Hopefully the information will be preserved in this webspace for a longer time! Bloomdoku Similar to Windoku, but the windows are packed more tightly together: You guys can try to explore more about this format (vanilla, killer, etc). But I am more interested in combining the NC (Non Consecutive) rule on this. Apparently the following puzzle has only 1 solution: NC Bloomdoku #1 NC Bloomdoku #1 solution: Here is a more human solvable puzzle: NC Bloomdoku #2 NC Bloomdoku #2 partial solving state: NC Bloomdoku #2 solution: |

Torn-Bloomdoku A petal is torn from the bloom, to destroy the symmetry: Apperently, combining with the NC (Non Consecutive) rule, this variant has only a space of 2 solutions! So to make a valid puzzle, only 1 more constraint is required: R1C1<>1. (Consider this: out of 729 initial pencilmarks, you only need to eliminate 1 to obtain a unique solution!) NC Torn-Bloomdoku #1 NC Torn-Bloomdoku #1 solution: A more human solvable puzzle: NC Torn-Bloomdoku #2 NC Torn-Bloomdoku #2 partial solving state: NC Torn-Bloomdoku #2 solution: |

Ninjutsudoku This variant is created for an overlapping variant called Ninja Sudoku, which I will post in the Gattai forum later. As you can see, apart from the 4 bloom petals, there are also 4 long axes surrounding them, as well as four "short diagonals" of length 4. You can consider those short diagonals as "zero cages" so that no cell values can repeat on those. This time I don't need to use the NC rule or any other rule to have a valid puzzle with 8 initial givens: Ninjutsudoku #1 Ninjutsudoku #1 solution: |

Interesting! I'll have to give those a try (at least the "human-solvable" ones). |

Simon I really enjoyed the NC but did not get anywhere useful with the other one - I feel I'm missing something (and so does JSudoku) Maurice |

Simon Sorry forgot about the torn ones, I meant Ninjutsudoku #1 I tried it when posted elsewhere and did not do well on it then - I think I am missing sometyhing on the zero cages, Apologies for not posting the JSudoku codes - I do not know how to post extra groups - but now realise I can post ythem as twin killers. I've got another way of filling out the Bloomdoku with X that seems interesting - I'll post a vanilla one shortly. Maurice |

For Ninjutsudoku #1, paste the following text code to JSudoku: text code 1: Then paste the following text code as "Twin Killer" in JSudoku: text code 2: (Alternatively, can draw them using "New Extra Diagonal" in JSudoku.) Then put in the 8 initial givens manually. It should be solvable in JSudoku, albeit with fishes. But if one can find a certain "backdoor", the puzzle can be solved much, much more easily. |

Here is a graphical walkthrough for Ninjutsudoku #1, to explain the "backdoor" I mentioned in the last post. My graphical walkthrough (15 images): |

Simon I'll try it again over the weekend before I look up your solution. Maurice |
