Standard Sudoku: each digit, 1-9, appears exactly once in each row, column, and 3x3 region.
Nonconsecutive: Cells that are orthogonally adjacent cannot contain consecutive digits.
Palindromes: Digits on a grey line read the same forwards and backwards.
Fog: correctly placing the first digits in the grid will reveal the hidden cell in the Eye of the Storm.
Solution code: Row 2, Left to Right
