@Luis2011 I hear you, I hate when my provider push apps I don't want to use. Many of them can be uninstalled freely but some no. But you can disable them. Go in Settings, Apps: Search the game you want to "disable" tap on it, press disable. When disabled the app won't show up in your app drawer and surprisingly will occupy less space (although it will be still there), it won't start up by itself, it won't update and use precious RAM.
I am sorry this is the only "clean" solution to get rid of unwanted apps.
