Normal Sudoku rules apply. Digits may not repeat in cages, and every cage contains a unique sum of digits. Digits along marked diagonals sum to the given totals.

There is an invisible 'cage thermometer', a single unbranching line which only moves orthogonally and visits every cage exactly once (though it can pass through more than one cell within a cage). The thermometer starts in the cage with the lowest total, and the total of each subsequent cage along the thermometer keeps increasing by 1. (I.e. a hypothetical thermometer would, in this exact order, move through cages summing to 100, 101, 102, 103, etc.)

There is also a simplified version of this puzzle with given cage totals. I built it during testing and thought some of you might appreciate a small hint if you get stuck with the "proper" version. You may click HERE to access the 'easy mode' of Thermokiller on F-puzzles. Just don't use it to cheat! (:

Finally, this is the continuation of my previous puzzle called Thermo Killer, a Sudoku with exactly the same rule set but a tiny bit easier, I would say. You may click HERE to get redirected to the Thermo Killer page.

And here's what this puzzle looks like:



Anticipated FAQ:

-Yes, the entire grid is covered in cages. That's also a bit of a hint if you know how to use it!

-The 'cage thermometer' does not have to visit every single cell in the grid. (In fact, it can never do that.)

-The 'cage thermometer' does not have a definite shape. As long as you follow the rules, you can shape it in whichever way you desire!

-After I built the first puzzle with this rule set, I was hoping this next one would be easier to set. I was wrong.

-I originally wanted to build it with JUST the cages and no additional clues, but this setting wouldn't solve uniquely without the little killer sums. I dare any constructor to try and build a variation of Thermokiller that way!
