Little Killer Counting (7 x 7)

Little Killer Counting (6 x 6)
My puzzle is a follow-up to Marty’s in an irregular 7x7 grid. I like to thank him for the nice discussions and for testing the puzzle. As always, your comments are highly appreciated. I wish you joyful solving!
- Normal irregular 7x7 Sudoku rules apply, i.e. each row, column and region has to contain the digits from 1 to 7 once each.
- Counting Little Killers: Digits along a marked diagonal sum to the clue outside the grid, if one is given. (If there is no conflict with other rules, digits on such a diagonal may repeat.) Moreover, any digit along a little killer diagonal indicates exactly how many little killers contain that digit.
Example: If a little killer diagonal has a 3, there are exactly three little killer diagonals containing at least one 3. Note: This does not necessarily imply that there are exactly three 3s on little killer diagonals.
Here you can solve the puzzle online:
Solution code: Row 4 from left to right (7 digits in total)

Thank you, this was fun! For me this was easier than the 6x6 (38 min vs 25 min), maybe because I did these back-to-back so I got enough practice with that one first :D

Thank you for your comment, juhish! I think the 6x6 and this one are similar in difficulty, so maybe it was indeed having the prior 6x6 practice which made this one look easier. Anyhow, I am glad that you liked this variant.

Thank you for your encouraging comment, Elker! Marty and I already had discussed to make a little series with this variant. Let's see how we get along with larger grids.

A really smooth and fun follow-up to the 6 x 6. A little bit harder by just the right amount... very nice ending too

Thank you for the comment and all your help, Marty! I agree that it is a nudge harder, but should still be in the 2 stars range. I am glad that you liked the puzzle and enjoyed its ending.
Kind regards, sujoyku
