Country : United States | Thanks, that was my guess. Perhaps "constraint does not apply" instead of "constraint is not valid"?
Also, working the IB examples clarifies the question. Thanks! |

Country : Switzerland | Fred76 posted @ 2013-03-24 7:29 PM Thank you for this wonderful test !
The set was really enjoying, well balanced, and all sudokus were perfectly constructed.
On a personal note, I broke the thermo-sudoku 2 times and hadn't enough time the 3rd time (there was 3 minutes left). It's a pity, because without these mistakes, I think it was within my reach to solve all sudokus in 120 minutes.
Fred
P.S.: and I forgot to say that I look forward to solve more of your sudokus during the next DSM (and I hope without mistake)

Phew !
I didn't remember that ! Perhaps next time I'll skip the thermo until I solved all other puzzles !

Country : Thailand | tamz29 posted @ 2013-03-24 8:34 PM I went straight for the Greater Than X and systematically tried X=1,2,3,4,5. None worked for me. Can't wait for the answers and the intended solving path.
Basically this was a 100 minute test for me because that first puzzle took away 20 minutes with no points. :(
Great sudokus from Richard as usual. I liked how there's plenty of practise puzzles that are available before the test. |

Great sudokus from Richard as usual. I liked how there's plenty of practise puzzles that are available before the test.
I hesitated to write that the Greater than X was overvalued, because I found it not so hard...
Here is a way you can find X:
-box 4: there are 4 pairs: the only possibilities are 1,2,4 or 5.
-you can eliminate the 2 with the 4 and 6 in Row 9 (4 cannot be next to the 6 ). It remains 1,4 or 5
-you can eliminate the 5, because in box 8, 1 has to be "X-consecutive" and it cannot with the 6, already present in the box. ->1,4
-It's a bit more difficult to eliminate the 1: If you place the 2 in R1C6, then you have 1 and 2 in R78C4, then it's impossible to place the 3 in box 8 (cannot be next to 2 or 4, and it cannot be consecutive to another digit ).
So X=4 !
Hope that helps !
Fred

Actually, I got X=4 very easily, but found the remaining Sudoku very difficult.
I have written a full walk through for this puzzle, that will be published immediately after the test is over. The puzzle has a perfectly logical solve if you know the way.
But I like to publish the notes to all puzzles at once, so I ask for a little bit of patience...  |

Me too, getting X was really quick. The rest was a big problem and I still kept breaking it. |

Then I found out that 5-9 was also a pair and it still didnt work... :( |
