    1. Yes. That one step opens up the whole sudoku. Whoever gets that break will find it easy. Others will struggle

  3. 7:55 on second try.
    On first try, I found that special step very soon but I failed to spot a naked single and I broke the puzzle after 25 minutes of painful and unnecessary bifurcation.

  5. 10:02. Found the trick within a few minutes--very cool!--but like Sudokanard I spent several minutes stuck until I found a naked single I'd overlooked. This was one of the most distinctive thermo sudokus I've solved--thank you!
