Have fun with my Sunshine-Sudoku.

The normal Sudoku rules apply: in each row, each column, and each bold-outlined 3x3 box, the digits 1–9 must each appear exactly once.

Additionally:

The diagonals: Enter the digits 1-9 on each of the two diagonals exactly once.

The sun: All cells touched by the sun are odd numbers.

Green lines: The digits in adjacent cells differ by at least 5.

Yellow lines: The yellow lines satisfy at least one of the following two conditions:

1. The sum of all digits in a yellow line is 14.

2. All digits in a yellow line are even.

Killer Cages: The digits in the cages add up to the specified number.

Kropki dots: Digits on white dots are adjacent; digits on black dots have a ratio of 1:2.
