Odd Sudoku 2013 - 1

In continuation to the preparation for the Grand Prix, today we are going to solve an Odd Sudoku. This is again an easy sudoku to familiarise people with the variant.

Odd Even Big Small Sudoku 2013 - 1

Next weekend we will see the second leg of the WPF initiated Sudoku Grand Prix to be hosted at the logicmastersindia website.

It is an innovative mix of puzzles and I would recommend everyone to try it. In order to prepare for the Grand Prix and also provide Practice material for all, I have decided to create sudokus which are going to be there in the actual competition. Karel at Sudokucup is also preparing some variants so I will not try and duplicate them, and will attempt to create examples of other variants.

To begin I have produced an Easy Level Odd Even Big Small Sudoku. Have deliberately kept it easy so that more and more people get accustomed to the rules of the sudoku and adapt themselves. Instead of the Japanese symbol notification, I have used the English Alphabet.

Every row, column and 4x2 box contains the digits 1 to 8 without any repetition. Additionally, The letters outside the grid denote the first two digits in the first two cells for that particular row or column.
E denotes even numbers. (2,4,6,8)
O denotes Odd numbers. (1,3,5,7)
B denotes Big Numbers (5,6,7,8)
S denotes small numbers (1,2,3,4)

Hope you enjoy this simple creation.

Non Consecutive Sudoku 2013 - 2

Today the Daily League completes 4 weeks. It has been a fun filled time. The week ends with another nice variation by Kwak. The booklet for week 4 will be available for download publicly in a few days time.

The second leg of the Sudoku Grand Prix being conducted by the WPF is going to take place at the LMI website next weekend. If you have not done so already then please register at the WPF site.

Till then we have a Non-Consecutive Sudoku today. I would rate it as medium difficulty level. Experts would take about four minutes to solve it, I would estimate.

Rules of Classic Sudoku apply. Additionally horizontally and vertically adjacent cells cannot contain consecutive digits.

Argyle 2013 - 1 new

Well, I have received feedback that the dark lines are causing a distraction so uploading a new version with lighter lines. Though this puzzle was for Last Thursday, but since people are still solving it at the Daily League, I am uploading it again so that people can solve it on the new one.
