Haunted River
I have been looking for ways to connect all the even digits orthogonally in a Sudoku, so far I have only found one way to do this. In this Sudoku you will discover this shape for yourself!
Rules:
1. Normal classic Sudoku rules apply
2. Cells seperated by a V or X sum to 5 or 10 respectively
3. Cells seperated by a black dot have a 2:1 ratio
4. The sum of the numbers in a cage must equal the small number in the corner of that cage.
5. The River: all even digits are orthogonally connected to form one shape (the river can branch and does not have to be one cell wide)
6. The river will divide the grid into islands (only containing odd digits), different islands cannot be adjecent (edge or corner)
7. The cell of a cage that contains the small number in the corner is always on an island, the number in the corner also tells the size of that island
Solve here: Haunted River Sudoku
Happy Solving!
Solution code: Enter the digits from column 1, then column 5. Enter top to bottom, do not use spaces.

I don't think I used rules 6 and 7

Easier than I thought it would be, I usually struggle with these shading/area types. The key is within the 6th rule :P

Edit: Clarified rule 7. Thanks to kublai for noticing

Can you please clarify rule 7? Is it the value in the cell or the small number in the corner that tells the size of the island? The rule seems to be written as the value of the cell, but I am running into all kinds of problems with that.
