played it cold before reading the post. first screen greeted me with the light switch, so i tapped past it to find the board. the how-to under it is the clearest sandwich-sudoku explanation i’ve read, the 0 and 35 extremes are the whole trick. one thought: what greets a first-timer is the light switch, not today’s puzzle. would landing straight on the board hit harder?
