Having just finished my last puzzle (a tricky 9x9 diagonal), I wanted to saw what an amazing job the Indian authors have done to provide us with a wonderful set of puzzles for SM 2023 Rd 1! Very much enjoyed the quadruples and there are a good mix of difficulties with some easier puzzles (classics, thermos) and some quite difficult ones (6x6 diagonal and odd-even, 9x9 diagonal and extra region). Can't wait for Rd 2 in a few weeks' time! :)
What is the reasoning behind allowing coloring for some puzzles but not others? Why not let the solver decide when they want to color?
Surface coloring is turned on for Odd/Even and No Three in a Row, but not for anything else. I routinely color, for instance, in solving extra regions; since this isn't allowed, it's hampering my solve.
Wow . That was a pretty intense contest. Had to solve out of my skin to even manage that score. Diagonal 9x9 was absolutely brutal and staved me off from finishing it for an eternity. I felt completely stuck not even sure where to guess. It was a relief to finish it finally with a wild guess.
Thanks to Kumaresan, Hemant and Arun for the really nerve wracking round :). My favourites are Quadruple (9x9) and Thermo (9x9).
