Rules:

Normal 6x6 sudoku rules apply.

Fog: The grid is partially covered in fog. Entering a correct digit will clear some fog to reveal more clues.

Counting Palindromes: Digits along a grey line read the same forwards as backwards. Additionally, a digit on a palindrome shows how many times that digit appears on that palindrome.

Non-Consecutive: Orthogonally adjacent cells may not contain consecutive digits.
