Normal sudoku rules apply. Digits in cages must sum to the number in the corner of the cage. Digits in cells separated by a black dot must be in a 2:1 ratio, digits in cells separated by a white dot must be consecutive - not all dots are shown. Digits along a purple Renban line must be a set of consecutive digits in any order. Digits along a red palindrome must read the same forwards or backwards. Digits along the blue diagonal line must not repeat.
