one step higher Sudoku-YY vengence series
(Published on 20. November 2020, 09:27 by bigger)
Standard sudoku rules applies. Fill the grid with numbers from 1 to 6 so each digit occurs exactly once in every row, column and 3x3 box.
the number outside indicate the sum of the first group of increasing digits in that direction.
There is a negative restraint, which mean the digit following the first group needs to be smaller than the last digit in the first group.
Here is a demonstration
Now come the main dish.
I know you may think it's easy. So one more with one more step. Now the first increasing group sum starts from the second digit in that direction.
one instance, if a row is like 231654, than the sum in the left should be 3 and the sum in the right should be 5＋6
Yes, they are all made by Old Miles.Since I'm a person who like to hold grudge, I provide Old Miles and another mystery guy with several ideas that will made everybody feel sorry about complaining too easy or not complete use of ruleset. It's safe to say n-sum is going to be the easyiest of them all.
By the way, if you find you are using somewhat familiar tactics, don't doubt yourself. This type of variant is a lot closer to skyscraper than n-sum. Maybe i'm just hinting too much.But I think nobody would actually read those attached at the back of the puzzle. Anyway, enjoy.
Solution code: the third row of the first one and the second one(12 digits)

I know it's a little bit too late to change difficulty. But I 'm just curious why you guys think this one is easy while the n-sum is average. As I recall, I finish n-sum without any special tricks(or maybe i do a lot battlefield back in the days).But this two don't have any easy number in the begining stage. The second one takes some time to rule out 3 cell sum. So is it the distaction in n-sum makes it harder or you use some way to make this one easier? I'm actually very curious about how you solve these puzzzles.

I really liked this concept, thanks for the puzzle. :-)
However, could you please leave a larger gap between uploading the sudokus to help slow down the current flood. This will be beneficial for both solvers and setters on this portal.
You can read more about the flooding phenomenon on the forum (which I learnt about from Richard):

Very nice! new type! very easy!
Covers two variants, and the external prompt numbers respectively indicate: 1. The increasing sum from the first cell;
2. The increasing sum from the second cell.
