Sudoku Straights
It’s only Wednesday, but I decided to present you with another Sudoku Straights puzzle. Remember that they are shown every Friday on the Daily Sudoku page.
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.

Thank you for the bonus puzzle. I love these so much, I added a weekly “appointment” to my calendar to remind me to check first thing on Fridays now.

Hi Pedja,
Since you invented this concept, I would be interested in seeing a 13 x 13 puzzle with straights, including 10′s, Jacks, Queens and Kings.
An interesting twist, if I’m remembering the rules right. Ones are replaced by Aces. The Ace could either go below the two or above the King.
Wow, I’m already addicted to these puzzles, but it would be great if you could make one (just for me?) like this!
Anyway, thanks again for a great variation,
Amy Grace
