this isn't a game but I used to be the same and never got any games that cost money.
Until I found the google surveys app, it gives you money for filling out surveys for Google (questions like "is this interesting?" and showing a pic of an ad. takes a couple seconds and you get $0.1-$1 from it)
now I have Stardew valley, Minecraft and about ~$30 just hanging around that I can use on the play store for movies or whatever. worth looking into if you didn't know about it
