Repeated Killer N1 2017

Last day of the year. Had created this puzzle as an example for the IB of the upcoming UKPA Sudoku Championships 2018.

On a lighter note, I thought of naming it as Serial Killer rather than repeated killer :)

Rules of classic Sudoku apply. Additionally, digits on the top left of a cage denote the sum of the digits inside the cage. Digits CAN repeat inside a cage.

Odd Even Count Sudoku 2017 - 1

And today we have the final request of Rakesh being fulfilled. We have an Odd Even Count Sudoku. I had thought that I will be creating this after coming back from the Times Sudoku Championship finals, but since I managed to create it in advance, here I am posting it. There will be a lull on Sunday as I will be out of town for the championship. See you all on Monday.

Rules of classic Sudoku apply. Additionally, An even number placed in a cell with a circle indicates the number of even numbers placed in the surrounding 8 cells. An odd number placed in a cell with a circle indicates the number of odd numbers placed in the surrounding cells. Numbers placed in cells without a circle may have either of these properties.

Next to Nine 2017 - 1

Today we have a Next to Nine Sudoku. Ya you guessed it right. Another request from Rakesh Rai. :)

Distance Sudoku 2017 - 1

Another request from Rakesh Rai. A Distance Sudoku. To be honest, this is the first time I think I am creating a Distance Sudoku in a very long time. I don't even remember the last time I created this variant. Creating new variants is a challenge I love. It helps me improve the understanding of the puzzle and while I try to maintain the uniqueness of the puzzle, the applicable solving techniques become more evident. Hope you all enjoy as much as I did while creating it.

Multi Diagonal Sudoku 2017 - 1

Another Sudoku that I created today. It is a multi diagonal sudoku. Rules of classic sudoku apply. Additionally digits cannot repeat on any of the given diagonals.

Its not straightforward but I would rate it medium difficulty.

Twin Killer 2017 - 1

After more than nearly 2 years I created a Twin Killer Sudoku. I plan to be more regular with my creations now and hope the patronage continues.

Twin Killer Sudoku.

The two killer sudokus given below have the same solution. Independently they may have multiple solutions, but the correct solution is unique for both of them.

No digit can repeat in any row, column and 3x3 boxes. Numbers on the top left of the cages denote the sum of all the digits inside that cage. No digit repeats inside a cage.

It is not too difficult a sudoku and hope you guys enjoy.
