You have three flavours to choose from. At SudoCue I will post it as Substitute Clueless Special #5. All three flavours #1A, #1B and #1C are variations of the same puzzle, i.e. they have identical solutions. A) The mainstream edition. B) The Oscar edition. C) The Glyn edition: 6 N/H Pairs/Triplets/Quads, 1 Turbot Fish, 1 Grouped TF, 1 Y-Wing. Regular Clueless Special #1A Rating based on required solving techniques: Barely Tough 007000200000800003300040086000000500075000004001000060009063020010020030000000007 000200005040007020270005060000000000600000010907000300001370000060800102500000006 000000000000400016800057003000000700019000400005000200000300100084600020000000000 070060800000750002004000970000000010607000008501000000010000000003270590020609003 000705803030060000560000201005000002004000030103000600010020048080103000000000000 400000000009004100002060054300000000097000002800000070030100006008700035040000290 062007000900000000800026910020000300005000000300000590090030008700005030003000100 000072600070508000600000010500000004009000065020000070002740806700050000400000000 000000100036008000008920005000000000000000890250000040500000009700600020000802000 Regular Clueless Special #1B Rating based on required solving techniques: Hard 007000200000000073300040086000000500075000004001000060009063020010020030000000007 000200005040600000270005060000000000600000010907000300001300000060800102500000006 000000000000400016800057003400000700019000400005000200900300100084600020000000000 300000800000750102004000970000000000607000008501000000000030000003270590020609003 000005003030060000560000201005000002004000030100000600000000048080103000000000000 000000000009004000002060054300000000097000002800000070030000006000700035040000290 062007000900000000800026910020000000105000000300000590090000008700005030003000100 000072000070508000600000010500000004009000065020000070002040806700050000400000000 000000100036008000008920005000000000000000890250000040500000009780600020000802000 Regular Clueless Special #1C Rating based on required solving techniques: Barely Super hard 007000200000000003300040086000000500075000004001000060009063020010020030000000007 000200005040000020270005060000000000600000010907000300001370000060800002500000006 000000000000400016800057003000000700019000400005000200000300100084600020000000000 302060800000750102004000976008000010607000058501000000810030000003270590020609003 000005003030060000560000201605000402004000030100000600000000048080103000000000000 000000020009004100002060054300000000097000002800000070030000006008700035040000290 062007000900000000800026910020000000005000000300000590090000008700005030003000100 000072000070508000600000010500000004009000065020000070002040806700050000400000000 000000100036008000008920005000000000000000890250000040500000009700600020000802000 |

The #1B also required one chain, but I did not record it, the most frequent tool was through hiden and naked triples. #1C was harder indeed, I used Glyn chain to brake it. Just for the record, the solution: Hidden Text: |

Good to see a post from you again Oscar. I have been missing your "regular" feedback. Oscar wrote: The #1B also required one chain The JSudoku Solver log for #1B reads:377 Naked Singles 161 Hidden Singles 66 Intersections 9 Naked Pairs 5 Hidden Pairs 3 Naked Triplets |

Hi Børge, I took some time off, visiting Italy! And now back to Sudoku fun time . It seems I will have to do again the #1B, without any chains this time I have great expectations for the new SS and its shortcuts, that would ease the clueless routine work. |

1a was a nice relaxing one. I'd probably even go with "hard" instead of "tough" on the Ruud scale. Perfect for a lazy Sunday afternoon. I should have done 1b instead but I just wasn't in the mood to think that much.... |

Done the #1B without any chains, took longer, but it was a good exercise on learning the possibilities of SudokuSolver |

I think you got the wrong thread here. This is the Clueless Special thread. End result is that the next version of the solver will quite happily complete all these puzzles using logic . . . . . . I don't like to be beaten!! Rgds Richard For CE-57226 both JSudoku 1.3b1 and SudokuSolver 3.0.3 can solve the SAME 20 cells using logic only. How many can the upcoming version of SodokuSolver solve? Can you beat JSudoku? |
