Normal sudoku rules apply. Place the digits 1-6 once each in every row, column, and 2x3 box.
Killer: digits inside a caged region must not repeat and sum to the total shown in the corner.
Thermometer: digits must strictly increase along each thermometer, starting from the bulb.
Even/odd: cells marked with squares contain even digits, and cells marked with circles contain odd digits.
Cells connected by an X sum to 10. Cells connected by a V sum to 5. Not all Xs and Vs are given.
Digits may not repeat along marked diagonals.
Solve in VariantDoku (iOS, macOS, Android) or on SudokuPad.
Lösungscode: Enter the digits of column 1.

Been really enjoying these puzzles with a nice cup of coffee to start my day for the past few weeks, thanks for the puzzles! Irregulars have been my favorite so far.

Totally didn't see the thermometer until the end, thinking I had a deadly pattern. Would have made the puzzle easier if I'd seen it sooner.
