The term "one shot" refers to a circumstance in which you only have one opportunity to achieve something. A one-shot is when you just have one minute to chat to the girl of your dreams and then you never see her again. A one-shot movie is exactly that, a single film that is released in theaters. The next day it's gone forever; you can't watch it again unless you buy a DVD or stream it online. Cinema is known for its one-shot movies because every time you go to the cinema you expect there to be a new movie playing. There are sometimes two or three films running at once and each one-shot movie fills up its own slot. Even if you don't mind watching the same scene over and over again, there's always going to be another movie waiting to play. Some people think one-shot movies are bad because they want more than one chance to win money. But actually one-shot games are good because it means that everyone plays equally likely outcomes. If someone has luckier rolls than you, they're going to win sooner or later no matter what game you're playing. And remember: life isn't about winning or losing, it's about taking chances until they no longer exist.
