Tourists in Rome

This retroactively serves as the tutorial for Roman sum lines, as a result I am gonna attempt to keep track of my puzzles that feature this ruleset.

• Roman Somedoku
• Fool's Fish

• Normal Sudoku rules apply.
• Dutch whispers line: Adjacent digits on an orange line differ by at least 4.
• German whispers line: Adjacent digits on a green line differ by at least 5.
• Roman sum line: Red lines can be divided into segments of 1-2 cells each, with each segment containing an XV (15) sum, an X (10) sum or a V (5) 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])
