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 in all rows/columns. (Be careful when applying hidden singles!)
4. And the main rule: numbers in one row/column that are between two black cells (or between a black cell and the border) must constitute a sequence, or if you prefer poker (texas hold’em or whatever) terminology, they must constitute a straight. Now, do not confuse this with consecutive sudoku! The numbers can be in any order, adjacent numbers need not be consecutive! Just like in poker.
Merry Christmas folks!
UPDATE: A new “Sudoku Straights” puzzle will be shown every Friday on the Sudoku variants page.
