Puzzle Name: Rounding Errors - Part 5
Puzzle Type: XV, Thermo, Palindrome
Puzzle Link: F-Puzzles


The auditors are relentless. They simply cannot stand pennies. I figured they'd be soothed a bit with an XV ruleset, but no... Once again, they have rounded all of the given clues to the nearest 5.

Rules:

With respect to the constraint clues, all GIVEN numbers in the puzzle have been rounded to the nearest 5, and that 5 can substitute for 3, 4, 5, 6, or 7, but do NOT have to represent the same number for two separate clues that use that given digit.

Any 5s that are NOT given must follow the rules of their respective constraints.

1. Classic: Normal sudoku rules apply, without respect to any other constraints.
2. Thermometer: Digits along thermometers must increase from the bulb end.
3. Palindrome: Digits along a palindrome read the same in both directions.
4. XV:
   
   • Two digits that share an X clue sum to 10.
   • Two digits that share a V clue sum to 5.
