I'm playing through Mario's Super Picross currently and after nearly 200 puzzles this one finally has me stumped as to how it is intended to be solved. What is the next step to solving this?
This is a "Mario" stage so the game penalizes mistakes and doesn't provide a mechanism for forward-solving/backtracking. I have "solved" the puzzle by attempting to fill the rightmost column and using penalty/lack of penalty to gain information about the correct solution, but I'd like to get this with logic!
I can write out the game mechanics in more detail if requested but I don't think they're super relevant beyond the above note.
