Any way to get PS4 games for free?

With a ski mask, at gunpoint at your nearest game store

No, there isn't, unless you get somebody to buy the games for you.

I tried this it works

hope it works for you

Ok so you can afford a PS4 but can't afford a PS4 game? Then what's the point of owning a console when you can't afford a game? But to answer your question there's no way you can get a game for free

You get two free games a month with psn + , that's the only way you can get free games
do you really think they give away games just because you want them and can't work more hours to be able to afford them?

Nope
