This is the first time, I created a puzzle with my own variant. I hope you like it!

Make sure to use the examples below, for a better understanding of the rules! :)

Normal Sudoku rules apply

Global Rule:

• All odd digits are orthogonally connected to each other. (e.g., all odd digits in Box 1 are orthogonally connected to the odd digits in Boxes 2-9) 
• Every even digit has at least one orthogonally adjacent even digit (not necessarily in the same box/cage!). There are no isolated, even digits (1x1 islands).

Blue Diamond:

• Indicates the total count of even digits that are orthogonally adjacent within its own cage. 
• A blue diamond always has at least one adjacent odd digit within its own cage. 
• Blue diamonds cannot be the same as other blue diamonds in orthogonally adjacent cages. 
• If there are no even digits orthogonally adjacent to any even digit in a cage (Islands), a "1" is entered in the blue diamond, see Example 1. 
• The adjacent even digits do not need to be all connected to each other (they do not need to form a snake), see Example 2.

Red Ruby:

• Indicates the sum of the numbers between two blue diamonds, see Example 3. 
• The red ruby in column 8 can indicate the sum of the numbers between S8R2 & S8R4 or S8R4 & S8R7, or both. The solver must determine which gap is being indicated.

Green Emerald:

• Indicates how many odd digits between the green emerald and the first blue diamond in the corresponding row/column are, see Example 4. 
• Blue diamonds, if odd, don't get counted.

Cage:

• The number in the top left corner of a cage indicates the number of odd digits within the cage. Not all cage numbers are given.

Kropki Dots:

• Digits separated by a black dot are in a 1:2 ratio. 
• Digits separated by a a white dot differ by 1. 
• Not all dots are given.

Little Killers:

• Numbers outside the boxes indicate the sum on the diagonal indicated by the arrow.
