no such thing

unless ur talking about warez or tegra zone apps

How did you get that Nova 3 on S3?

because it wont show up in Play store from my S3..

ROOT

MC3. Nova3, Dungeon hunter, Asphalt etc etc etc..
They arent searchable from play store..
It just wont show up..

Indeed they don't. If you got a S2 they will show up.
All you have to do is transfer the .apk to the S3 and install it.
If you bought, it it will pass the license test und run as smooth as you have never seen them before.

What I did to get NOVA 3 and MC3 on it without a PC:

--On my previous phone (Galaxy S II)
1) Purchase and install the game(s) from the Play Store (did not start them up)
2) Use Astro File Manager (free, needs root), Backup Apps, tick any you want to transfer
3) Opened Dropbox, Upload, internal sd -> backups -> apps -> upload the APKs

--On the Galaxy S III
4) Open Dropbox
5) Go to wherever you put the APKs, press the arrow on the right of each for more options, press the three dots, Export. Remember where you've chosen to export them.
6) Open My Files app, go to where you exported the APKs, select each and install!

DONE.

Only annoying thing is I keep accidentally pressing the menu button with the edge of my palm when playing games in landscape on the GSIII...bit annoying.
