Google Hangouts

I'm looking for advice on what App to use in conversation and phone calls to someone who lives out of the country. Should I use Google Hangouts, Google Hangouts Chat, or does anyone have any other suggestions? I would greatly appreciate any help you could possibly provide. Thank you

I own an Escape Room. Since right now everyone is practicing social distancing, I would like to run my Escape Room games virtually. I would like to allow approx 4 users to log in to play. They can chitchat a few minutes before their game to get to know each other. Then once the game begins, I will introduce myself and give them the plot to their escape game. I will have a wide-angle camera mounted to the wall to show the room, and as the game master, carry a tablet or webcam around as players talk to me and direct me to show them certain items in the room, move in for closeups in certain areas, try lock combinations, etc. I will be their hands while they solve the puzzles. I am not sure if Google Hangouts Google Meet or Zoom is better for this. I did try it yesterday using google hangout meet and it was good, but I think there may have been a wifi issue where it was choppy. Just trying to figure out the best option. Thank you! Catherine
