Any idea why it is called "Number 5 Still Alive". Is it based on some movie or song name?
It is almost certainly referring to the movie "Short circuit". |

Location: ITALY | number 5 still alive is known to be very tricky. It is based on a principle that you can apply to "classic killer" sudoku. That is, you just have to add-up the unit digits, forgetting about the tens. The leftovers, together with the known areas, have to sum up ?5. For example, if your dotted areas show the digits: ?4, ?3, ?1 the sum is ?8. Any leftover cell or group of cells must end up with ?7, as ?8+?7 is ?5.
That is, because you want the sum to be 45, so it must end with a 5.
Like this, in the number 5 still alive, all of the areas have ?5, so the sum can either be ?5 or ?0, letting you figure out what the leftovers can be. |

Location: Poland | Great contest!
Time limit was perfectly fixed. Also very good points distribution , maybe besides Just One Cell - it took me at most 5 seconds. ;)
The best puzzle constructions: Numeral, Double Diagonal, Termometer, Number 5, Killer.
Congratulations to You, Serkan. |

Location: The Netherlands | Thanks for the puzzles Serkan.
I just checked the results again and I seem to have lost points (only realised as I switch places with xevs). I think my Numeral Sudoku Entry went from 65% to 50%. I was pretty sure I submitted my last 2 puzzles in the 65% and 50% zone, not both in the 50% zone. This was how it was listed before. Why did it change? |

Location: ITALY | Checklist of possible mistakes in this competition:
1) Completing a puzzle, but sending only half solution [DONE]
2) Printing the Outside Sudoku on a recycled paper, so that some numbers are covered with other prints [DONE]
3) Printing the Thermometer Sudoku in low-quality [DONE]
4) Completing the row and column for the solution, then continue finishing the sudoku, and seeing the time runnig over just when you're pasting on the submission page [DONE]
5) Completing the Just One Cell in just three seconds, and spending one minute to check whether it is REALLY correct [DONE]
6) Leaving the Double Diagonal for last [DONE]

I just forgot to submit one answer (a grid solved between 70th and 90th minutes) 
I don't mention other misadventure that happened to me during the test (1rst one was a power cut - that lasted 50 minutes - just at the beginning of the test, when my printer hadn't finished to print. Fortunately, I didn't choose to play all test online, and my printer had enough time to print enough grids...)

The only thing I regret is that I completely lost concentration in the last 30 minutes and broke some puzzles. |

Neeraj and others,
1. No points for typo unless it is on a clue
2. Please don't post exact digit here - you are giving away a clue to others. |

There was a mistake in the score page - it was giving 65% to puzzles submitted upto 110 minutes (it should have been 105 minutes). It was fixed much later in the day, definitely much later than when you completed the test.
That is the reason of the change, sorry about the confusion! |

Location: India | Beautiful Puzzles Serkan..... Loved the Double Diagonal and Thermometers the best.... When I saw the IB I thought 120 minutes would be less for 22 puzzles but it turned out perfectly timed... Thanks for the great set...

Location: India | Beautiful test Serkan. I think every sudoku had its own charm in solving and thats the mark of a good author.
I personally liked Group Sum and Quadruple the best of the set. |

Location: United States | Thank you Serkan -- this was a very nice set with as much quality as quantity. I enjoyed the puzzles during the test and will continue to enjoy the many I did not finish during these two hours. Thank you again. |

Location: ITALY | I have completed this very good test (with two stupid mistakes, when will I give up this) and yesterday morning have seen the first time the result sheet. But now when I try to look at the result I just see the page with the nicks of those who have started or completed the tests without score. Is this intentional or is it just aproblem of communication I have? |

Location: India | forcolin, you should be able to see others scores as well, please check again. The score page should show others scores.
Please send me a screenshot of score page, if the problem persists.
What about others? Is anyone else facing the same problem or is it forcolin only? |
| |
|
Location: India | I realized why you are not able to see the score page.
Goto the test page. Click on "Start Fivefold", after that go to the the score page. |

Location: India | it was a great set of puzzles. i had actually thought of doing well before the test . but for the first 10 miutes app. i was still collecting the printouts (courtesy - my printer). and with 70 minutes gone i had done only 4 low pointers and also got the killer wrong . i knew i had goofed up big time. spending the last 50 minutes was terrible with my group sum going wrong. it was a test where i did more wrong than right. but it was a wonderful test |
