4 Fanged Vampire

(Published on 18. October 2024, 20:03 by isajo4002)

Normal 4x4 sudoku rules apply There are four 4x4s in the grid In every row, column, and box there is one vampire cell. different vampires in a 4x4 grid have different values. Vampires take exactly one sip of blood from an orthogonally adjacent cell. Vampire cells count as increased by exactly one and the taken cells count as decreased by exactly one. Every value is at least 1.

No two of these 4 puzzles contain vampires in the same cell. Each grid has it's own rules

Grid #1 Killer cages: values in cages must sum to the given cage in the top right corner. digits may not repeat in cages

Grid #2 Arrows: values along an arrow must sum to the value in the circle.

Grid #3 kropki: Values separated by a black dot must have a 1:2 ratio. All dots are given

Grid #4 region sum lines: Values on blue lines must add to the same sum in each box. The digit in the cage is neither vampire nor prey



play on sudokupad. Sorry I couldn't get a photo

Solution code: The values of each row left to right that corresponds with each grid in order eg. row 1 of grid 1 followed by row 2 of grid 2 etc.. (16 digits no spaces)

I thought I "solved" the puzzle, failed to enter the solution code, and then realized that I had not in fact completely solved the puzzle! Wonderful rules, thank you!

A lot of unusual rules here, but really a journey. Honored to see a puzzle like that with vampires.
