Black and White Killer Sudoku (Daily Sudoku League #102)


Black and White Killer Sudoku appeared in Sudoku Surprise test which was held in November 2014 on Logic Masters India website. Author of this test is David McNeill. With this post I want to thank David McNeill for this wonderful set of puzzles for Sudoku Surprise Test. 
Today's Black and White Killer Sudoku is slightly different from the one which appeared in Sudoku Surprise test. In the original Sudoku full grid was sub-divided into cages. However in the present Sudoku there are some cells which are not part of cages. I have updated instruction of the puzzle, so that this change is clear.

This Black and White Killer Sudoku is my 102nd contribution for The League of Extraordinary Ladies and Gentlemen

Rules of Black and White Killer Sudoku
Fill numbers from 1-7 so that each row, column and 3×3 box contains the digits 1-7, a black circle and a white circle. In addition, some parts of the grid is sub-divided into cages. Each cage contains exactly one circle and some digits. All cages with a black circle must have the same digit sum. Similarly, all cages with a white circle must have the same digit sum. The respective digit sums may or may not be different. Digits cannot repeat within a cage.

Author of World Puzzle Federation (WPF) Sudoku Grand Prix 2015 Round 4 is Jan Mrozowski from Poland. This championship will be held from 27th March, 2015 to 20th March, 2015 online at WPF Sudoku website. Previous round 3 of WPF Sudoku Grand Prix. was authored by Indian puzzle creators in which I was one of the co-authors for the test.
There are many interesting puzzles in this championship with few puzzles being the new Sudoku Variations e.g. Between Sudoku and Sukaku Sudoku. In fact Between Sudoku already appeared in recent World Sudoku Championship 2014 with slight rules changes. I have also prepared one Between Sudoku. The difference in the current Between Sudoku are previous one is that currently between numbers appears in all the given digits whereas in the previous version of this Between Sudoku numbers with such property were marked with circles and lines connecting these circles. It mean that in the previous version even on some of the diagonals are rules of Between Sudoku can be applied but in the current version these rules only applies to Rows and Columns. 
This championship contains following Sudoku variations. I am posting the links to the practice puzzles for these Sudoku variations. Be aware that some of these practice puzzles contain additional rules.
1. Classic Sudoku
2. Windoku,
3. No Touch Sudoku
4. Irregular Sudoku
5. Diagonal Sudoku

6. Roman Numeral Sudoku
7. Between Sudoku and
8. Sukaku Sudoku

I am enjoying participating in WPF Sudoku Grand Prix. Looking forward to this championship over the coming weekend.
