"Video chat with the whole family, face to face to face.
Be together, even when you’re not together. Jokes get funnier, big news gets bigger, and surprises get more surprising when you’re catching up in person.
1) Video chat with up to 9 people
Hit the “Invite” button and add more friends to your hangout by clicking on their pictures or entering their names. You can also invite groups by selecting your Google+ circles from the dropdown menu.
2) Make conversations more fun
There's always more to do when you're in a hangout. Click the "Apps" button to watch YouTube videos with your friends, play poker, wear pirate hats, or even doodle with your kids.
