Normal sudoku rules apply.
Normal thermo rules apply. Cells along a thermo strictly increase in value from the bulb to the tip.
Additionally, every row column and box contains exactly one doubler. For purposes of thermos, the digit on a doubler counts as double the digit it contains.
Every digit from 1 to 9 is doubled exactly once.
Have fun, leave a comment if you enjoy the puzzle!
Lösungscode: Row 1 followed by Row 9

I stand petrified !
Another great installment with doubles, with similarities in the logic compared to your previous one. It is easy (and probably intended) to get misleaded by previous knowledge about thermos!

This is a cool concept. Many elegant pieces of logic, and it solves very smoothly. Thanks!

Nice idea! It made me a bit paranoid for a while, but I managed to pull through. :-)

beautiful puzzle. took me some time to correctly figure out doubler on thermo but after that deductions flowed slowly and logically. Thanks for sharing

Can I have some clarification please. What is a doubler?
[It just doubles the value of the cell. So a 7 on a doubler counts as a 14 for example.]

Beautiful logic! I'm loving this doubler concept, I look forward to seeing it used with other standard constraints, particularly the arithmetic ones.

This one hooked me at the start and didn't let go till the end. Some really neat use of the doublers here.
