Freemium games- free to install but pay to play. You are prompted to make in-app purchases to continue playing - probably to unlock new chapters, buy new weapons etc. Six - Guns... Well, all the best items are priced in Sheriff Stars and now it's tough to get them even in events... Everyday there are adverts to buy this or that our check out some new promotion in the shop and whatnot... Totally Freemium.

The opposite of Freemium games are Paymium games. They usually cost money to download but after that you don't have to make any IAPs or anything to complete them (like games by Rockstar on Android).
