Psycho Alien
(Published on 29. August 2021, 03:01 by Bremster)
- There are some thermometer shapes in the grid. Along these thermometers, digits must strictly increase from the bulb end.
- Red cages are psycho killer cages. Digits placed in cages point to boxes in the grid, and provide a referred digit which is the digit in the same position in the box that is pointed to. The referred digits in the cage must sum to the small clue in the top left corner of the cage. Referred digits may repeat.
Psycho Killer with Thermo Rules Example
In this example the 4 in the PK cage points to the cell in box 4 in the same position, so it points to a 1. The 3 in the PK cage points to box 3, in the same position so it points to a 1. 1+1=2, so 2 is the total of the PK cage.

This puzzle is amazing once you get your head around psycho killer ruleset. I hope there is more of these.
BremSter: There are two other Psycho Killer puzzles I have posted to LMD on my profile, and there are more I am working on; including another thermo one that is no where near this hard.
