Earthquake in Sudokutown #4
(Published on 4. May 2021, 12:08 by PrimeWeasel)
There has been another earthquake in Sudokutown. In the epicentre was a read-out of 9.0 on the scale of Richter.
Earthquake Sudoku Rules apply.
All cages are Richterscale read-outs (like 6.8 or 4.1, for instance) and they follow Killer Sudoku rules (Digits sum to the value in the cage and digits can not repeat). These read-outs are read from left to right, or top to bottom. Read-outs can not be repeated in cages.
Furthermore, there are 4 rings around the epicentre where read-outs are done. Read-outs in rings closer to the epicentre must be higher in value than those in rings further away from the epicentre.

"Read-outs can not be repeated in cages" means that the richterscale read-outs between different cages cannot be the same, even if they are on the same ring? For example, if the readout of a cage is 6.3, even if it is on the same ring, there can be no cage with the readout of 6.3, and there are no other cages with the readout of 6.3 in the whole grid?
I'm not sure whether the misunderstanding is caused by the translation problem, and whether it is the original intention of the puzzle, but this constraint really helped me solve the puzzle successfully.
~ That is indeed what it means. When there is a 6.3 in a cage, it can not be anywhere else, and you definitely need this information for this particular solve. I unfortunately don't have control over what a translation would look like
-I successfully solved several puzzles without using this rule, so I accidentally forgot it. This constraint seems to be necessary for this puzzle, because if it does not arrive, it seems that it will lead to a deadly pattern in the end.

It looks like some of the cages don't have values. Am I missing something?
~ Not all cage values have to be known to solve this Earthquake. The rings and the fact that read-outs can not be repeated are very important for solving. The first Earthquake, #3 or the Mini Earthquakes are easier Earthquakes which can be found amongst my puzzles.

Just a thought, what's in the centre of the Sudokutown? Why 9 always lived there? Did he think the earthquake was just another massage?
~Definitely a thrillseeker!

"[T]hey sum to the digit within the cage" doesn't make any sense.
I see what you mean. I'm not a native english speaker and tend to make these mistakes every once in a while. Thanks for pointing it out and making the puzzle henry.
