Normal Sudoku rules.
Palindrome
The sequence of digits along a gray line reads the same forwards as backwards.
Killer
Digits in the cage do not repeat and sum to the small number in the top left corner of the cage.
Little Killer
Clues (with arrows) outside the grid show the sum of the digits along the indicated diagonal. Digits can repeat along this diagonal if allowed by the other rules.
Sandwich
Clues (without arrows) outside the grid show the sum of the digits sandwiched between the 1 and the 9 in that row/column.
Consecutive Pairs
Cells connected by a white dot contain consecutive digits. Not all possible dots are given.
Even
Cells with a gray square contain even digits.

Thanks again :-) Setting this one was tricky... to find a working arrangement of the palindromes with the intended visual theme.
