Hello I really like Picross games, and am usually good at it, but this time I'm stuck, and I don't understand what to do. Note that I ONLY solve picross using the logical elements, never solve them by deduction (form or guess). I only look for perfect score and don't want errors on any of my puzzles, so I don't like just trying random things either. in Picross 3D round2, there's a "hint" mode, which is usually good. But this time, it's telling me to mark or remove cubes, but I don't see what I should do on that column, nor the next one right to it. Could someone provide a logical analysis on it and explain me what I'm missing? puzzle N° 119, in hard mode. there's (3) (3) for the marked column so, 2 groups of each color, a single and a double for each color. why should I remove or mark one? The remaining unmarked cube could be either blue or orange, right? Edit: I think I can restart it from the beginning, sometime solving it in a different way prevent being stuck and in a position where all the hints are not solvable mathematically/logically.
