Event Horizon
(Eingestellt am 13. Januar 2021, 23:50 Uhr von steelwool)
In the Sudoku universe, cells meet an antiking condition, so the same digit may not appear a king's move away.
But there is a Black Hole at the center of the Sudoku universe.
Black Holes are strange, and very odd things happen at the Event Horizon of Black Holes.
At the Event Horizon the antiking rule no longer applies.
It's difficult to be sure where the Event Horizon is, but it is one of the coloured rings around the centre.
Discover which of the coloured rings is the Event Horizon to solve the puzzle.
Normal sudoku rules apply.
Cages sum to the given value with no repeated digits.
Little killer diagonals sum to the given value and may repeat digits.
The antiking condition means the same digit cannot appear in a cell next to another in any direction, like a king's move in chess.
You can solve the puzzle in f-puzzles
Lösungscode: Enter the digits of row 8, followed by the digits of column 2.

I was able to solve this without using the antiking constraint anywhere
-- Well done then. It's entirely possible, it is very simple. But you can resolve at least 3 digits quite early on using the condition.

@VeTaurus, yeah i only used the anti-king in the white and was able to solve. it's a nice puzzle, just the rules need slight clarification.
-- Hi, I changed the puzzle by adding the outer pink area. If you think about this, you will see that you need to know where the event horizon is to know when you can use anti-king condition. But that situation has not really changed from before.

To be honest... I don´t understand the "event horizon" rule. Like "bigger" I found the two adjacent 1s in box 5 and 8 very early. But this means that blue and yellow are rings without the antiking rule.
I then had two adjacent digits in box 2 and 6 on the blue ring. And even with another pair of adjacent digits on the green ring I got the correct resolve code.
What am I missing?
So inside the event horizon (blue area) the anti-king rule no longer applies. The universe is split into two areas, one where you can use anti-king to make decisions about a pair of digits (eg resolve the 3-2 in box 6). If you do not use this you can probably still solve the puzzle without considering anti-king, but it is easier to use it. And you know not to try using anti-king inside the blue area.
