I did it in 3:04. Coloring slows down this puzzle, as it was easier to use killer cages. 15 and 7 cages have no 3, so C is 3, cage 13 without 3 and 4 is 256, so r1c1 is 1. Column 6 had 3 as r1c6, and bellow it cage 11, so rest sum is 7, meaing 5 is missing for cage 12 in r6c5. Row 6 has 3 + cage 12 + 5, meaning r6c6 is 1, resolving cage 12 etc etc
Oh interesting.... you did it very differently to me. My break-in I used the logic of the two bottom 12 cages and the triangular number for 6, which gives r5c6 as 4-5-6 and r6c1 as 1-2-3 but in combination with the 7 cage in box 1 you can restrict r6c1 further and it starts getting you digits.

Super fun puzzle!
Slightly tricky. Well done. 🎉

7:24 fun puzzle!
A slow 6:29 for me, I'm not great at killer combos.. Some nice mathing using the" secret" - now to watch and see how the pro did it!
