When I was younger, all I wanted to do is go to the casinos, even tho I didn't really blow much money. I was always not allowed or was removed from them due to my age. Now I can go because I'm past the age restriction, I really don't because I got bored of it and it's just a waste of time and money, also it puts me in a bad mood.

Good decision. The slot machines are the ones that attract me the most and I know that I need to stop so I just play slot machines on amusement parks for an alternative so I can stop that addiction and losing a lot of money.
You also adopted a good way to reduce your addiction of gambling. I think putting slot machines in different public places is the best alternative for all the gambling addicts and it could prove very much valuable to the governments to reduce the percentage of gambling addicts if the governments will start working on it because these machines provide the same fun as gambling is having in it and people forget gambling easily.
This will mean that people under 18 will also start playing on this machines as their is no age restriction and their country will have more gamblers from early ages. i doubt this will be done by any country unless they think about only of the money as a revenue source then they can do it.
That would be the implications if this machine will be available, but I think government will think twice before allowing this to happen, they allowed
casinos as those business pay taxes, and if this slot will be available outside worse thing can happen and it will also affect the taxes of the casino
house as players will play outside instead of visiting the place.
