Rules
Normal sudoku rules apply.
Box borders divide each blue line into segments with the same sum.
Along the gold line, digits do not repeat and no two digits appearing anywhere on the line can be consecutive.
Along green lines, adjacent digits differ by at least 5.
Along pink lines, digits form a consecutive sequence in any order.
Within a cage, digits must not repeat and they sum to the small number in the top left corner.
Solution code: Column 6

I finished the last version and now this one too. I'm unsure which I prefer, the other one was pretty hard but I did like it. Though an easier one like this is fine too and I do like it

ND: I received a lot of feedback for the first version so I tried to improve it.

Funny and easy - if you know your lines. Thank you very much for creating and sharing.

VitP is clearly frustrated, but this puzzle is easy and smooth, BUT you do need to know the standard tricks of four different types of lines. So I can't recommend this to anyone who hasn't experienced all four types before. That makes it hard for me to decide between 2 or 3 stars difficulty.

there is no world in which this is "easy", despite multiple claims to the contrary. you can quite literally fill 25% of the grid with digits, and 25% with limited candidates before there is even a whiff of a contradiction.
the reality is this:
1) you start with extensive preparation, studying all the cages and lines. already we are in the realm of "experts only", as beginners will struggle with this, and there are no "easy" cages or lines.
2) in order to advance, you have to choose between about 10 different paths, 9 of which are "dead ends". there is a SINGLE pressure point (the 5 in box 8), but this is the LEAST likely path to choose, because it has the most white space.
3) AFTER that step, the rest is smooth sailing.
you CANNOT take a process, delete a critical step, and claim that what's left is correct.
that's why rockets blow up, planes fall out of the sky, and generally bad things happen.

I tried the first version a couple of days ago and could not get anywhere. This one solved as smooth as silk. Thank you for providing this more approachable version, NicoD!
