"Kid-friendly" but really kid-robbing, though - AFAIK most of arcade games that let you win something, e.g. a toy, have subprograms that can override your victory, making it look like you've lost; those are triggered randomly, based on venue-configurable parameters like "max winning rate" and "daily wins threshold". This is designed to ensure the venue always makes a profit, by turning what's advertised as games of skill into games of luck.

What really angers me about this is not even that the nature of these machines isn't advertised to, or generally known by, parents and children, but that the way those overrides are implemented, they're quite literally gaslighting children (and for kids playing on such machines way too much, it's likely ruining their hand-eye coordination). There are many slow-motion / high-framerate YouTube videos demonstrating how these arcade games will fake input delays to turn perfectly timed win into what seems like split-second loss. And don't get me started on the fuckery that goes on with those "toy claw" games.

I feel there's something deeply corrupted about screwing up with children like that. I mean, when my kid starts playing a game and thinks she got good at it, and wants to show me how good she is, and then the software override kicks in and the game lies to her that she lost, what am I supposed to say? Gaslight her further by saying it was bad luck or still big enough of a challenge - when I know perfectly well the real reason is a bunch of greedy adults with broken moral compass adding a biased RNG to what they advertise as pure game of skill?
