Couple of doubts with the IB.
1. Mastermind Sudoku - I thought the 5 digit code will be given. In the IB it is not.
2. The Dominos given in the appendix has no similarity with the 'Domino Sudoku' |

Country : India | @ Deb:
You are right about the Mastermind Sudoku, the code will be given in the puzzle. I forgot to enter it in the IB.
For the IB example the code is "28471"
I have not seen this puzzle type before an wanted to have a simple introductory puzzle. However in the future I think puzzle creators can choose to create puzzles without the code given, where identifying the code will be a part of the puzzle solving process.
The Dominos example is not similar to the Domino Sudoku, but that is the best introductory example I had. I have also created a separate example for Domino Sudoku which should make the rules of domino Sudoku pretty clear. More examples can be found in previous Japanese Number Place Championships.

Country : India | thanx.....I wasted so much of time indentifying the code...........but the puzzle was one star when the code was known.
One request to organisers - please see that the grid lines are marked properly in the puzzle especially the region boundaries as in Sudokuro it was difficult to identify regions as the boundaries were not bold at places. |

Grid lines will be marked properly in the puzzle pdf and also online flash |

Can you please tell me if in the minesweeper sudoku of IB, r9c3 shouldn't be coloured in grey? If not, can you tell me the solution, because I've done a mistake :( .
Thanks

Fred, I'd created this example, and here is the solution.

Country : Israel | amnon posted @ 2010-03-13 6:47 AM I think you should swap r2c4-r2c5 and r8c4-r8c5, otherwise r8c3 should be grey, as Fred suggested.

Country : India | For participants who are solving online in the flash format:
In puzzles like Easy as Sudoku and Minesweeper you can use an X do to identify a blank space or a mine respectively.
For participants solving by taking printouts, enter X in the solution instead of the blanks in your answer row/columns.

Thanks for nice puzzles. But there must be a problem with Word Search Sudoku. After I started the mock test I took my printouts as usual and started to solve. When I opened the puzzle book pdf file I examined Word Search Sudoku and there exists only 3 given letters. One at R6C2, one at R5C5 and one at R4C8. I quickly got stuck and couldn't succeed. But when I was submitting my answers of solved ones I noticed that for this puzzle there exists 6 more givens in the flash format. I wish I had notified this earlier (when I notified this I had only 4-5 minutes to finish test) and dealt with it in flash format. Anyway thanks again for nicely designed sudokus:)
Regards,
Zafer |

Sorry about the error in Word Search sudoku.
I updated the Word Search Sudoku in the flash version after feedback from Rajesh that it is a little difficult to get a start in the puzzle, but forgot to update the same in the pdf version.
For all participants who are yet to particpate please take note of the update in the Word Search Sudoku Flash format.

Piratesudoku is also wrong. 3 digits are not matching with the expected answer.

Country : United States | This was my first time doing this and so I have a question about the scoring. Why does it only check a few lines from the solutions entered? I noticed that I actually got the domino one wrong, but my error wasn't in the line that was checked, so it was scored correctly. Also, are we supposed to only submit certain lines, or the whole solution? |

Only selected rows / columns are checked. There is button "Show cells to fill". If you click on the button, it will show the cells you need to fill.
The information used to be there in earlier booklets. Looks like we need to put it back. |

There are many participants who solve the test by taking printouts of the puzzle pdfs
So to save their time required in submitting the answers we ask the participants to enter a few rows/columns.
These rows/ columns are generally chosen in a way that they are solved at the very end of the solving process, so in most cases you need to have solved the rest of the puzzle correctly to reach the correct solution digits.
You were lucky with the domino Sudoku :) |

Country : United States | Thank you for your responses. I did solve on paper and then fill in my answers. I wish I knew about the selected rows... would have saved some time instead of filling in the whole puzzle online (although only a few minutes I suppose). |
