Location: India | 1] For online mode, will the rows/columns be automatically marked from the start, or will we need to click on "show cells to fill" 21 times?
2] For offline mode, how do we fill the answer key for "Just One Cell sudoku"? Just the number or the cell notation too? For online mode, I presume we just need to fill the key cell and click on submit. |

Location: India | I think the name could be fall out of puzzles like XV and kropki where 5 cannot be derived from cell where clues are given... just a wild thought

D1 - Musketry Sudoku will have 2 diagonals marked. These diagonals are 12-cells long. All other puzzles will have a combination of 2 rows / columns marked. See note below for E4 - Just One Cell Sudoku
Online Solvers
1) The order of Sudokus will be exactly same as in IB, except that D2 will appear before D1.
2) E4 - Just One Cell Sudoku - You must fill exactly one digit in the grid. If multiple digits are filled in the grid while submitting, you won't get any points. It is okay to have pencil marks around the grid (you don't need to clear the pencil marks before submitting)
Paper Solvers
1) The password protected puzzle booklet has 12 pages. There is no cover page. D1 and E5 appear on single pages. All other pages have 2 puzzles each
2) E4 - Just One Cell Sudoku - The answer format is "Co-ordinate of the cell, followed by the digit in the cell" e.g. EN3 (No special characters, you enter exactly 2 letters and one digit). See image below for co-ordinate system.
3) Paper solvers who don't want the grids to be loaded in their browser can use this link - http://logicmastersindia.com/M201107S/?paper=1
As usual, players are free to choose the mode of solving (paper or online or mixed). Your last submitted answer and its timestamp will be considered for scoring.
Point claims for typos will not be accepted, unless the typo is on a given digit.

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: 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? |

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. |
