Back when the pandemic started, this video by 3Blue1Brown got many people talking about logistic curves in an epidemiology context. It made me think about how frequently game designers also use S-shaped curves, so I decided to write an article about them. Upon doing some research, I found many interesting usage examples of sigmoid curves in game design, and decided to make this compilation, also adding a bit of my own experience. I hope you like it!

What are sigmoid functions?
