Normal 9x9 Sudoku rules apply. Place the digits 1-9 exactly once in every row, column, and 3x3 box.

Shade all even digits so that no more than two consecutive cells in a row or column are shaded or unshaded and no 2x2 area is fully shaded or unshaded.

Digits separated by an X must sum to 10.

Digits separated by a grey dot are either consecutive or have a 1:2 ratio. 

Have fun.
