Rules

• Classic sudoku rules apply
• Palindromes: The two grey lines are palindromes. If a number appears as the Xth cell from one end of a palindrome, it must also appear as the Xth cell from the other end. Additionally: Cells on both palindromes are all either high digits (6789) or low digits (1234) i.e. palindromes are both high or both low.
• The "S-shaped" area enclosed by the two palindromes contains digits ONLY from the opposite polarity to the palindromes and the digit 5. i.e. if the palindromes contain digits (1234) the enclosed area contains digits (56789). The sum of the digits in the enclosed area is a prime number less than 135.
• Arrow: Numbers along an arrow must sum to the number in the circled cell.
• Kropki dots: Digits separated by a black dot are in 1:2 ratio, digits separated by a white dot are consecutive.
• Killer cage: Numbers in the cage must sum to the given total of that cage in the top left.
