What is Commercial Game?

I am in big confusion about game publishing. If i publish my unity android game in AppStore for free, then what is that meaning it is Commercial game or OpenSource Game? Paid games only be the commercial game? Any help would be much appreciated.

Commercial Software

Every software that has the ability to gain money is commercial. No matter if you have advertisement plugins, in-app-payment systems or if it’s a paid software in the first place.
