This puzzle really didn't need the distraction of working out which cells were low and which high as it just flowed with actual values, starting with the 12 cage which had to start 1,2 and then either 3,6 or 4,5 That meant the 10 cage in box 7 could only be 3 and 6, thus confirming that the 12 cage could only be 45 and so on.
Also a 4 cell 12 cage (box 1&4) always has a 1&2 in it. Combined with the 4 in box 7 forces the 10 cage to be 3&7. Then the 31 cage just fills in leaving the 45 to for the 12 cage.
yep. He was so focused on 5s it was distracting. I lumped 5s in with the high digits and colored it that way, started with the 12 and Box 7 and was done in 22. Sometimes a puzzle can be too straightforward for pro solvers and setters.
Interesting how different people use different techniques. I did not use high/low. For me, I used the killer cages (as mentioned in other comments.) No shame there. My goal is to solve the puzzle, not be distracted with the math and human error. But what broke this open for me was the location of the 1s and 9s. Then I used the possibilities as per the killer cages and as mentioned here in another comment.
Great! I learned something new about Thermo/Cages too. How to find the high digit on the Thermo. Take the average of the cage total and divide by the # of digits in the cage. Then add one for each cage count over 2. So example, take the 20 Thermo/Cage in box 9. The average is 20/4 = 5 then add 2 more since it is a size 4. The high on the thermo must be at least a 7. Only a few cages don't work like the "31" in box 7 doesn't work for that formula and the "22" cage in box 3. That turns out to be 8 or 9 as possibilities.
12:26 - Nice easy one. Now to see why Bremster struggled with it; it’s very unusual for me to be even close to his times! Edit: I see now. It’s not a H/L puzzle. I started with the 12 cage which is very restricted, followed by C3 in box 7.
Cool! 15 cages are always low + [4/5/6] + high! As you proved in the fully entropic case, and 4 is low and 6 is high for the case of {4,5,6}. Also, killer cage calculator is a bit of a cheat for this puzzle ; )
the way to get a "fast" time in this puzzle is to FOCUS on the cages, and use the thermos only in a SECONDARY role. this is, after all, a "cagey" puzzle. 1) basic cages force the 1,2 in col 3, the 9 in box 3, and the 4 in box 7. end of phase. 2) cage combinations give nothing useful. end of phase 2. 3) col 3, box 7 is forced, and this forces all of box 7. after that, just keep picking from the lowest branches. no need for "goodliffing" anything here. that just uses up time. triple are generally completely forced, due to the thermos.

about 18 minutes for me, but with *extreme* reliance on the killer calculator. This is definitely one for the math heads. Great construction.

i found it easier to fill in the bulbs with their max values first. flowed easy from there.
Wow! That was seriously cool!I loved how well the thermo-cages worked.
Nice puzzle. And very approachable! 13:48 for me. 😁
The remaining two digits in cage 6 is the way to go, they need to add to 10 and the only option is 4 and 6.
Also a 4 cell 12 cage (box 1&4) always has a 1&2 in it. Combined with the 4 in box 7 forces the 10 cage to be 3&7. Then the 31 cage just fills in leaving the 45 to for the 12 cage.
13:90 , fun puzzle!
14:00 to solve. This pack is brilliant!
8:02 for me, nice and easy puzzle
Done in 10 mins. GAS level. 12=1236or1245

Using the Sven calculator I got this one pretty quickly (7:28). But I needed to go fast to solve more sudokus today 😅

Nice and easy, done in 6:05

8:27 for me, almost a gas puzzle - my favourite sudoku is killer sp the thermos made it easier.
I'm not good at this combo , couldn't quite figured it out.
Nice puzzle tho and the solve helped a lot.
19:20 very manageable

5:39 for me!
5:09 for me
nice puzzle
Great … done in 10 mins
21:32 for me.
it took me only about 15 min to get through this, and i'm intermediate level ... and slow. so why is this video 40 min long?

For me this one is more about math and options to complete the cages. Started with box 6, and then went smoothly counterclockwise. Resolved in 7:24
Done in 03:53, but the killer calculator was on.
