Rules:
Normal sudoku rules apply.
A vampire cell appears once in every row, column, and box, which preys upon X of the (up to) 8 surrounding cells, where X is the digit in the vampire cell. A prey cell's value is 0 and a vampire cell's value is the sum of the digits in the prey cells it consumes plus its own digit. Vampires cannot consume each other and multiple vampires cannot consume the same prey. Values in a cage sum to the given total. Digits cannot repeat in a cage, but values may.

Very fun and tough. I found it amazingly smooth and approachable. I almost skipped it bc the 5* difficulty but I’m so glad i played it!

Very cool puzzle but so hard. There's some great maths to be used here, and the logic at play here felt almost more like pseudoku or doppelgänger logic (since vampires prey on multiple cells). Really novel, really fascinating to unpack, quite fun. Certainly quite tough. Thank you!

Fascinating puzzle! Also quite challenging to track all of the possible ways sums can be affected by Vampires - especially across box borders! 0.0 Once you start to understand the flow of this puzzle, you realize that it could have been made much much harder, and that it the most terrifying thought of all… This IS the easy version!

What a masterpiece!
It must have been really difficult to set a puzzle with this constraint, and indeed it was very hard to solve. I kept being amazed that it actually works and that I could keep making slow progress with so many degrees of freedom.
For me it felt like 5* with most of the difficulty in the first third or so of the solve, especially while untangling the bottom left box. Although it is pretty clear where you need to focus your attention at every step.

I really like this twist on vampire cells, as it leads to some very interesting logical deductions. The greater-than/less-than operators on all the cage values is nice touch. Great puzzle!
