The X-Haven

(Published on 31. March 2026, 05:18 by Krisonium)

I've been inspired to create my own version by these two incredible puzzles here: Bates Motel and Nakatomi Plaza.

Normal 6x6 sudoku rules apply.

Killer Cage: In every cage, all digits must be unique and their sum must perfectly match the provided total if given. In this puzzle, every cage must be filled using only the digits available to the grid.

X-sum: Clues outside the grid indicate the sum of the first X digits in that row or column, where X is the first digit seen from that direction. All outside cells on a clue must contain a digit.

Puzzle:

I wanted to use a long, hockey-stick-shaped killer cage for the rightmost clue, but this version will do.

Solution code: Row 3 including the outside X-sum digit. (7 digits)

Fix wording.

Yeah, the "match the provided total" rule should be removed, since the with the next rule all totals are 21 anyway

It's very easy and very cool! But also, the description is a bit confusing (cages match the provided total? there is no provided total). You could reword it so the cage total *is* a clue maybe

A very cute little puzzle. The logic flowed steadily, one cage after another.
