The brief
Normal Sudoku rules apply. Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.
Equality cages: Cages must have an equal number of low (1,2,3,4) and high (6,7,8,9) digits AND an equal number of even (2,4,6,8) and odd (1,3,7,9) digits. Equality cages can never contain 5. Digits may not repeat in a cage.
Kropki dots: A black dot between cells indicates cell values with a 2:1 ratio. Not all dots are shown.
X: Adjacent cells connected with an X must sum to 10. Not all X's are shown.
Region SumDrome: Digits along lines have the same sum within each box the line passes through. In addition each segment (defined by the box borders) equidistant from the center must have the same digits in any order. For example, if R6C8 was 2 and R6C9 was 6, R7C7 would be 8, and R8C5+R8C6 would be 26 or 62.
