Thermo 6x6 is insanely difficult whilst all other 6x6 puzzles - after the break-in and careful deductions - quickly melt away. I've put 7 numbers in and I'm truly stuck - any hints?

Would be great if in future rounds, the penpa links can be retained in the pdf for practice after the contest is over.

Can you share where you are stuck (like a screenshot), so it's easier to guide/provide the next step?

Thank you Kumaresan Sir for a properly challenging set of sudokus. My first experience in a while with solving online, and I was clearly rusty. Favorites were Quadruple (Really satisfying solve) and Thermo 9x9's. I got stuck for long periods on the Quadruple and Diagonal, and before I knew it, completing the test was beyond me. I like the difficulty level, and the introduction of an extra variant.

Following multiple requests, Round 1 has been extended by 24 hours. There won't be any further extensions.
