How to play paid pre installed games free?

If you buy a new phone you will see that some games and apps are pre installed .
They only give you one or two trials and than ask for money .
But i will found how to play those games again and again. To know how to play follow my steps:-

1. When you use all trials and than they are asking for money .

2. Go to settings >apps and than swipe window towards left again and again than u will see a "all" named window in which you will see all system apps.
