EITBON 6: Cognitive Reversal

(Published on 8. August 2025, 18:18 by Neokart)

Hi everyone. This is the 6th part of the series inspired by The Carebear's album "Everywhere in the Beginning of Nowhere". I hope you like it.
The rules and choice of colors are a reference to the puzzle Synapse Retrogenesis.

Rules:

1. Sudoku: Each row, column and outlined 3x3 box contains each digit from 1 to 9 exactly once.
2. Palindrome: Digits on a grey line must be the same read backwards and forwards.
3. White dots: Digits joined by a white dot are consecutive.
4. Black dots: Digits joined by a black dot are in a 1:2 ratio, i.e., one is double the other.
5. Blue dots: Digits joined by a blue dot are in a 1:3 ratio, i.e., one is triple the other.
6. Pink dots: Digits joined by a pink dot are in a 1:4 ratio. i.e., one is quadruple the other.
7. Green dots: If two digits are joined by a green dot, one must be an exact multiple of the other, i.e., larger ÷ smaller = N, where N is an integer and may vary from dot to dot.

I think there is a typo. "5. Blue dots" "are in a 1:3 ratio" I guess.
