NATMOS 1: I'll Keep Holding On

(Published on 11. October 2026, 07:16 by Neokart)

Hi everyone. Two years ago, I started creating puzzles with the series inspired by The Caretaker's album "Everywhere at the End of Time". Today marks the start of a series of puzzles inspired by The Caretakers' fan project "Nowhere at the Millennium of Space". The design of the grids will refer to the covers made by Barnum Effekt.

Rules:

1. Normal sudoku rules apply: Each row, column and 3x3 box contains each digit from 1 to 9 exactly once.
2. Region Sum Line: 3x3 box borders divide the blue line into connected segments with the same sum.
3. Palindrome: Digits on a gray line must be the same read backwards and forwards.
4. Kropki Pairs: A pair of digits joined by a white dot are consecutive. A pair of digits joined by a black dot are in a 1:2 ratio (i.e. one digit is double the other). Not all possible dots are necessarily given.
