Happy New Year 2025, everyone!

The rules are as follows:

Normal Sudoku rules apply

Clues outside the grid indicate the sum of the digits on the indicated diagonal.

Digits inside cages must sum to the total in the top left corner of the cage. Digits within cages may not repeat.

Additionally, the digits 2 and 5 must conform to anti-knight rules. No other digit must necessarily conform to this rule.

Cells joined by a V sum to 5. Not all Vs are necessarily given.

Digits along thermometers must strictly increase from the bulb. Additionally, the sum of the digits on a given thermometer must equal either 20, or 25. The value for each thermometer is to be derived by the solver.

The puzzle can be played at F-Puzzles here!

The puzzle can be played at CTC here! NOTE: I cannot for some reason get the anti-knight checker to turn off in the CTC app. For those who use the conflict checker, I recommend setting it to "Classic Sudoku" for this puzzle. I am certain this is the fault of the setter (me). I apologize for the issue.

Questions, comments, concerns and jokes are all welcome! Thanks for playing!
