I wasn't sure where to put this, it isn't a problem about the forum, it's the interactive puzzles linked on the main page. Diagonal Sudoku puzzle SetA 9x9 008 is a messed up puzzle - starts with two given 1's that are in the same row. Just wanted to let someone know...

That was badly damaged. Removed from the list. :-)

In interactive puzzles Sudokux XV/setA/9x9-H1 I am unable to find the wrong with the following solution.
148 562 397
753 914 628
692 873 415

386 741 259
974 285 136
521 396 874

419 637 582
865 129 743
237 458 961

Can any one reply me what is wrong with this solution

There is no V between 1 and 4 in row 2.

Remember that in XV puzzle, converse rules apply. That means, all possible places of X and V are marked. If there is no V, sum of adjacent digits cannot be 5. Similar rule for X / 10.

OK Thanks. This rule can be included in the instructions

It is already there.

Hi. I'm not sure where this question should go, and/but I haven't seen it answered on the forum. I'm relatively new here. I greatly enjoy the puzzles. I'm not trying to compete, not into speed or guessing, so I enjoy going back to previous contests and solving them at my own pace. [Though I do love getting the daily classic Tapa online!].

Anyway, there's generally not a need for answer key for most problems, since you usually know when you've solved them. But going back to previous Tapa Variations Contests, I'm less certain on some of the more exotic varieties if I might have missed something that otherwise looks right. Is there a place where the answers to the old contests (in the answer key form used) can be accessed?

As of now, it is not available to public, although it is stored in our database. We will spend time to make it available publicly.

However, if you are looking for the complete solution for any old puzzle, it may not be available with us. We encourage everyone to post in the forum asking for the solution, and surely some of us will be able to provide the solution.

I appreciate the quick reply. I think that the "answer key" should be sufficient most or all of the time. But thanks for the advice about posting a request if needed. And definitely "thanks" for considering taking the time to make the answer keys available!!

Solution codes are now available for all tests in 2011 and 2012. For example : http://logicmastersindia.com/lmitests/?test=TVC9#puzzles-table

For tests in 2010 and 2009, it will take some more time.

Perfect! Thanks.

Hey guys, I'm am new to this website and find it particularly hard to navigate here. I would appreciate if someone familiar with this website (like a mod or Rohan or Administrator) could give me simplified instructions so I could get to sudoku-solving. I've read FAQ and stuff like that but frankly, I'm confused.
