Trio Knights Non Consecutive Sudoku 2013 - 1

In continuation of twisting up the Trio, I decided to take it a step further. Thought why not try it with a Knights Non-consecutive constraint. This has turned out better than yesterdays twist.

Rules of classic Sudoku apply. Cells which are at a Knights step from each other cannot contain consecutive digits. Grey cells can contain only the digits 1,2 and 3. Yellow cells can contain only the digits 4,5 and 6.


Trio - NC Sudoku 2013 - 1

Trio Sudoku has always been one of the basest of Sudokus. Its like three different set of sudokus rolled into one. I was just sitting and wondering how I could make the three individual sets interact and decided to add the Non-Consecutive constraint to it. The result was quite pleasing and here is a Trio with a Twist.

Diagonal Sudoku 2013 - 3

Well, Its time I restarted posting on the blog. With the regional rounds of the Times Sudoku Championship underway, 2 rounds have been completed and two more to be conducted over the coming weekend. Top 4 players from each region will take part in the finals at Mumbai on 3rd August.

Winning the Chennai round was quite satisfying on a personal front. Irrespective of the competition, I was more concerned with accuracy and my solving speed. Leaving nothing to chance I spent a whopping 7 minutes in round 2, checking to make sure that there were no errors or blank cells, mistakes which I have made plenty in the previous years. Was glad to see that no such issue had occurred and I had all correct. The final will be a different ball game altogether and I look forward to renew the battle with Rohan, and Prasanna now amongst the fore runners, its going to be an interesting battle. It bodes well for the Indian team if we all qualify as that would ensure a really strong Indian team at the WSC.

Todays puzzle is a bit tricky Diagonal sudoku. Lot of people found the Diagonal Sudoku in the Chennai round to be tough and asked me to post something related to Diagonal Sudoku. Please feel free to try it and if stuck do not hesitate to mail or ask me on the blog.
