Hmm, let's ponder for a while what could I have meant. Soooo, do I put coins into my SNES or Genesis? Hmm, tough question, but if I had to give a definitive answer, it would be no. For multiple reasons, really. Like not having SNES or Genesis. And there being no slot for coins. Well, technically there's a slot that you can put coins into, but it's better to put the game cartridge there.
So, long story short, no I don't. But where else would people in the past put coins into to play games? Well, that, my dear reader, is left as an exercise to you.
Apparently it is what is known as a rigged rental which is the equivalent of a quarter muncher. The game was so difficult that it would be to hard for new players to beat during the rental period to force them to buy it. It doesn't seem like there was an actual arcade version, just a case of mixed metaphors. edit: typo
Now a single skin for a single character is the price of an entire game, or multiple games in the case of the newest Jinx skin for league of legends, thanks.
