Ok, I know a lot of people found the Double Delights a bit of a head spinner. I was just dabbling around trying to see if we could have three variants in one puzzle and the following puzzle is the result. I promise you I wont provide anymore "treble trouble" puzzles after this :)
Todays Puzzle is a Diagonal Untouch Killer. Rules of classic sudoku apply. Additionally, the two main diagonals contain digits 1 to 9. A digit cannot touch itself even diagonally and sum of numbers in a cage equal to the number given at the top left of the cage. No number repeats inside a cage.
Finally the weekend in over and so is Double Delight. It had been 2 hectic days being connected constantly in case any participants had a problem. Thankfully everything went off without a hitch or a glitch. WaterlooMathie of Canada took the first position followed by Thomas Snyder (2 time World Sudoku Champion) and Jakub Ondrousek (jaku111) from Czech Republic taking the third position. From the Indians Perspective, the top three Indians were Rohan Rao (Current National Champion), Gaurav Korde and M Jaipal Reddy.
From an authors perspective it was a mixed test for me. There were a total of 173 participants and 132 non-zero scores. Which means that 41 people decided to not submit any answers for whatever reasons.
But in the same breath as an author it was really heartening to see the feedback given by the 2 time World Sudoku Champion, Thomas Snyder on his blog,on the puzzles. Here is the link to Thomas' blog.
Todays puzzle is a Greater than(Inequality) Diagonal sudoku. Rules of classic sudoku apply. Numbers follow the mathematical operations of less than or greater than as per given symbols. Additionally the 2 main diagonals contain digits 1 to 9.
