The brief
**Sudoku, Renban, Kropki** - Standard 9x9 sudoku: The digits 1 through 9 appear in every row, column, and box without repetition. - Renban Lines: Digits along a Renban line must form a set of non-repeating consecutive digits in some order. - Kropki Pairs: Digits in cells separated by a black dot are in a 2:1 ratio. Digits in cells separated by a white dot are consecutive. Not all dots are necessarily given.
