it's not really a pinball, it's an art display piece using basic pinball mechanics to simulate trade mechanics. it's simple to play by design, the trading balls with other players aspect of it is the more essential part

i mean like, if you can't even be assed to read the article (lol):

"In Andy's original concept for the game, the five players represent members of a small community, each of whom plays a certain role – one makes shoes, one grows corn, one drives a transport truck, etc. As they individually play pinball on their own playfield, they accumulate balls that represent the goods they provide.

In order to keep playing, however, they periodically require some of the goods provided by all the other players. The game alerts them to this fact by illuminating a "Trade Now" button on their playfield.

I'm growing corn, and at some point I'm going to need new shoes," explains Cavatorta. "And now I have to trade some of my corn – which is represented as pinballs – with the person who makes shoes. But they're in the middle of their game, and they might not need it [corn] at the same time as me. They will eventually, but I have to get them to stop their production of what they're doing. This becomes the dynamic, where you need to convince people to engage with you.

I want strangers to talk to each other, and I want there to be this unpredictable social component, where people's personalities come into play," says Cavatorta. "I actually wanted this to be somewhat chaotic – you can't really guarantee how it's going to go. If somebody doesn't speak the same language as you, and you're trying to coordinate trading with them … well, now you're having an interesting experience you can say something about."
