I have a mobile app that runs tournaments with cash prizes.
I want to add a sentence which I'm not sure it's correct grammatically:
The prize increases every time one of your friends join.
Can a prize "increase"? Is there maybe any better way to say this?
Absolutely no problem in increasing prizes. In fact, the use is pretty common. Say, for example, a lottery prize can increase in certain cases.
You can find hundreds of instances where prize gets increased in terms of money or something else. Just one little concern though - everywhere, the increased amount would be somehow mentioned.
Here, in your case, the prize would serve as a reward that would increase every time users' friends join the game.
