Do I need to go out often to play Pokemon Go?

You do encounter some Pokemon when you are stationary for a long time but if you really want to catch stuff you'll have to walk around and visit spots.

Catching a lot of Pokemon is the (only?) way to get stronger in order to capture Gym's for your team (red, yellow or blue).

To get the best out of Pokemon Go you'll need to go outside to visit PokeStops and Gyms. While you can get Pokemon when you are stationary for a while you won't encounter them as much as if you'd go outside.

No! You can actually considering walking around in your home and find a couple of Pokemon every now and then. I've myself caught 4 Pokemon around my house itself in the span of 2 days.

However, if you're looking for something like roaming around in the city and siting on sofa at the same time, it looks difficult. Though it's possible through a crook! Check this : How To Play Pokemon Go Without Moving
