AntiKnight Sudoku 2013 - 3

Today is an Anti-Knight Sudoku for the Daily league. Things have been hectic and hence the puzzle updates for blog have become infrequent. Soon there will be a news update for all so keep watching this space.

On the Daily League, we have had a splurge of great puzzles as always. I haven't solved any this week, but indeed to do it later this weekend.

Friday was Tom Collyer's 8 is still alive which was renamed as A Date with 8. I will take credit for that :)
Saturday was Bram's 10 Box Sudoku.
Sunday was Kwaka's Odd Sudoku.
Monday was Fred's Diagonally NonConsecutive Sudoku.
Tuesday was Prasanna's Galloping Horses.
Wednesday was Bastien's Figure Sudoku.

Rules of Classic Sudoku apply. Additionally, a number cannot repeat at a cell which is at a Knight's step, as in Chess, from itself.

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.
