Happy 100th Stream, Tris!

(Published on 15. May 2026, 17:47 by sujoyku)

This puzzle was set to celebrate Tristan’s 100th stream on the Zetamath Youtube channel.
I like to thank all testers and wish you joyful solving!

Rules:

- Normal sudoku rules apply, i.e. each row, column and 3x3 box has to contain the digits from 1 to 9 once each.

- Region Sum Lines: Box borders divide the blue lines (Tris) into segments with the same sum. (Different lines may have different sums.)

- German Whispers: Adjacent digits on a green line (100) must have a difference of at least 5.

- Little Killers: Digits on a marked diagonal must sum to 10.

- Kropki: If two digits are joined by a black dot, one is double the other. (Not all black dots are given.)

- V: Digits joined by a V sum to 5. (Not all V are given.)

Here you can solve the puzzle online:

@madhupt : i confirm that's really obvious R can only be a single line !

Very nice puzzle! However, the rules must specify that the part of R in box 5 is one single line. Thanks for sharing.

Thank you for your comment, madhupt! I thought that R was a single line is pretty obvious. Otherwise: Where should it be split into two lines? That would be completely arbitrary, wouldn't it? Or did I maybe misunderstood your remark? Anyhow, I am glad that you liked the puzzle.
Kind regards, sujoyku

Very nice! A bit tricky in the mid-solve, so I gave it 3 stars. It is not that tricky if you just happen to focus on the right cells and ask the right questions. Thanks
