You heard right- they do t just get harder though. They get far far more random- often times you only have one or two possible moves, or you have one okay move and a couple useless moves near the top of the screen. That turns it into literally a slot machine. So it becomes absolutely a matter of trying 20 times, and the game only gives you three free lever pulls per 24 hours.
