Normal sudoku rules apply. Digits along the palindrome lines must read the same forward and backwards. Digits in a quadruple circle must appear in the surrounding cells. Digits in a cage must sum to the little number in the upper left, and may not repeat in the cage. Neighboring digits marked with a white Kropki dot are consecutive. Not all dots are given. I think this puzzle is 2 stars out of 5 for difficulty for many solvers. As always, comments welcome!
