Cellphone help

Hey,I have a Samsung T98 something dont know the rest.
And when i try to put games on it,it doesnt show up,
I downloaded them from different websites and still doesnt work.

When i first put in the mem stick in the adapter it had The Music,Images,Sounds,Videos folders already on it,but i didnt know where to put the games so i made a folder Called Games.
And when i put it there it still doesnt work.
