Introducing “Sudoku Sequences” or “Sudoku Straights”

Here is a brand new Sudoku variation as a special Christmas present. Hope you will like it. The rules: 1. Use numbers 1-9. Numbers cannot be repeated in rows/columns. 2. There are no nonets (3×3 boxes) like in other Sudoku puzzles. 3. Black cells do not contain numbers. Therefore, not all numbers 1-9 will appear […] Related Posts Plugin for WordPress, Blogger...
