Even Odd Chessdoku 2013 - 2

Today we have another Chessdoku, but this time it also doubles up for the League's puzzle. The week has started off interestingly with some great puzzles Arrow Sudoku by Fred, Search 9 by Prasanna and a Renban Sudoku by Bastien.

I hope the chessdoku lives up to the level set up by the previous authors for the week. This is not a difficult puzzle but then it does require a wee little bit of thinking.

Fill the grid such that every row, column and 3x3 box contains the digits 1 to 6, a Chess King(K), Queen(Q) and Knight(N). Additionally, a King cannot attack another King, a Queen cannot attack another Queen and a Knight cannot attach another Knight. Each piece following their moves as in chess. Grey cells can contain only even digits and the orange cells can contain only odd digits.

Summer Magic 2013 - 1

Kwaka beat me to the the summer magic sudoku at the daily league.

Fill the grid such that every row, column and 3x3 box has digits 1 to 6 and 3 blank cells in it.Numbers outside the grid show the total of all numbers appearing in corresponding rows and columns. These numbers are separated by at least one empty cell. Example: 12_3_456__ = 471; 6543__21_ = 6564.

EvenOdd chessdoku 2013 - 1

I was just dabbling with an idea for the Chessdoku and thought why not add the even odd constraint, which will help reduce the number of givens drastically. Here is the result.

Fill the Grid such that the digits 1 - 6, King(K) Queen(Q) and Knight(N) occur once in every row, column and 3x3 box. Grey cells can contain only the even digits, yellow cells can contain only odd digits.

A Chess King cannot attack another King, a Knight cannot attack another Knight and a Queen cannot attack another Queen.

AntiKnight-Nonconsecutive Sudoku 2013 - 2

Last one week has been  hell and effects are still there on my health. Still not completely recuperated but atleast able to login and get back to some sudoku creation. Hopefully there won't be any more disruptions in the puzzling activities.

Today's puzzle is also part of my contribution towards the Daily League group on FB. It is an Anti-Knight Non-Consecutive Sudoku.

another development for the daily league is that now all people will be able to solve our puzzles online at the sudokucup.com website. I will be posting links and more details on that shortly today. In the mean time enjoy this puzzle for today.

Rules of Classic Sudoku apply. Additionally, consecutive numbers cannot occupy orthogonally adjacent cells and a digit cannot repeat at a knights step from itself. Basically a nonconsecutive sudoku and an antiknight sudoku rolled into one.

Little Killer Sudoku 2013 - 1

It has been a one hell of a tiring week. Too much of travelling and sudoku creation for a few championships. I am packing my bags for another bit of travel as I get ready to upload this puzzle. This Little Killer Sudoku serves the Daily League at FB as well as practice for the WPF GP that takes place this weekend on the German website.

At the Daily league wed had a wonderful start with an Equal Sudoku by Cristoph. A very well made sudoku. Tuesday was Prasanna's turn with a Between 1 and 9 sudoku which was again very well made with only two given hints. Wednesday was Bastien's Fortress Sudoku.

For the Little Killer, apply standard sudoku rules. Additionally, digits outside the grid denote the sum of all digits in the corresponding direction of the arrow.
