That's a game compatibility issue, you should contact the game developer(s) so they can fix this.

i think it is not a problem with dewelopers because before update all of games work, after upgrade maybe 2 games work so i think the problem is update and i don't know how to fix that or how back to my old software

The game worked fine with Android 4.1 but now with 4.2 it doesn't work, that is a compatibility issue that game and app developers have to address. 

To downgrade you have 2 options

1. take it to a Sony repair center, they might be able to downgrade your phone 

or 

2. use flashtool
