Roman Somedoku

Following the footsteps of blackjackfitz, I have created a Sudoku of my own using the somedoku ruleset, coupled with Roman sum lines of my invention.

• Somedoku: Each cell contains one of the digits from 1-9. Every Nth row and every Nth column each contains N unique digits with the remaining ones being duplicates.
• Kropky dots: Digits separated by a white dot are consecutive. Digits separated by a black dot are in a 2:1 ratio. Not all dots are given.
• XVXV: Digits separated by XV sum to 15. Digits separated by X sum to 10. Digits separated by V sum to 5. Not all XVs, Xs and Vs are given.
• High-low line: On a yellow line, adjacent digits alternate between being strictly greater than 5 and strictly lesser than 5.
• Roman sum line: Red lines can be divided into segments of 1-2 cells each, with each segment containing an XV sum, an X sum or a V sum, and with every 3 consecutive segments containing one of each. (i.e 2373965 can be divided into 23-73-96-5 [V-X-XV-V])
