Solve Recaptcha 2.0, grid size
-
is there any solve method that also sends size of grid? I emulated capmonster API but image is received without grid info. I know that most of the time 300x300 is 3x3 and 450x450 is 4x4 but I saw much more variants like 2x3 and at least few others. Why other solvers don't need to know this info? They assign grid size based on task name? Like bus, hydrant, store?
