Is there another name for this puzzle? (Kyudoku, Nine Find)

Question

Is there another name for this type of puzzle? I can only find two examples of it online:

• https://www.brainzilla.com/logic/kyudoku/
• http://ninefind.com/

In the game you start with a 6x6 grid filled with the numbers 1 to 9. One number on the grid is circled. The aim is to remove numbers (you can't remove the circled number) so that:

• The sum in every row and column is 9 or less
• Each number (1 to 9) appears only once

For example, you might start with this grid:

9	2	5	1	5	8
9	9	7	9	2	7
2	6	8	5	5	3
1	3	⑤	5	3	4
3	6	2	7	8	2
3	5	9	7	5	6

And remove all of the number 5's except for the one that is circled:

9	2	-	1	-	8
9	9	7	9	2	7
2	6	8	-	-	3
1	3	⑤	-	3	4
3	6	2	7	8	2
3	-	9	7	-	6

You can then remove the numbers 7, 8 and 9 from column 3 because, when added to 5, the answer is greater than 9. And so on, until you end up with a grid that looks like:

-	2	-	1	-	-
9	-	-	-	-	-
-	6	-	-	-	3
-	-	⑤	-	-	4
-	-	-	-	8	-
-	-	-	7	-	-

Answer 1

I believe not. We did just learn about it existing a few days ago. Plus, googling the word Kyudoku gives this link and this video, so I believe that Kyudoku is the only existing name.
