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 (i.e. one digit is double the other). Not all dots are necessarily given.
Cells connected by a V sum to 5. Not all Vs are given.
Digits may not repeat along marked diagonals.
Solve in VariantDoku (iOS) or on SudokuPad.
Solution code: Enter the digits of row 1.

I didn't need bifurcation but the interactions between the different constraints made this tricker than a 1* for me.

Happy birthday!
I agree.

My Birthday! ^_^ Tricky again. Probably just at the edge of 1*. Though people should stop rating these 1* if they're solving through trial and error.

It’s very hard for me to find that middle ground between “this is easy” and “I need to bifurcate this.” :)

I’m getting better at finding the pressure point to apply bifurcation, but I really wish I could more reliably solve these without experimentation.
