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 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.

    Tried first one yesterday but didn’t realise they had to be sequences…. DOH!

    BUT they are great fun! In fact we’ve enjoyed all the variations, apart from Boxbreaks and greater than, which we can’t really get our heads around!

    Hi djape
    I have purchased several of your kindle puzzle apps. My particular favorites are the calcudoku and sudoku straights.

    The sudoku straights puzzle is particularly addictive. I think you need to promote them more on your Web page.

    Also, I would like make a suggestion: make this variant go “around the corner.” That is, just like many card games that go around the corner by having Q, K, A, 2 …… as a continuous sequence, make this version do the same with 8, 9, 1, 2 …….

    I think it will introduce some additional twists.

    […] will be more Jigsaw Sudoku puzzles on the Daily Sudoku page. They will be accompanied by the Sudoku Straights puzzles, which is something new, but I think you should learn. There will be fewer (non)consecutive […]
