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.
Kropki: digits separated by a black dot are in a 1:2 ratio (one digit is double the other).
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) or on SudokuPad.
Solution code: Enter the digits of row 5 (no spaces).

This feels vaguely computer-generated. It wasn't hard but none of the deductions were particularly aesthetically pleasing.
