Quoted from zaphX:Unfortunately you have to do this for each game you start.
You can do it mid-game though, I generally do it if I feel a heater coming on.
We have an auto-claim and auto-submit feature in Account Menu > Settings > Playing Preferences. If you set auto-claim, when you play a game with the app and there is only one player on it, it will claim player 1. With auto-submit, when you finish a game, it will automatically save it to the leaderboard.
The app must be open for this automation to work, though. The good news is we're moving auto-submit to the background so the phone can be locked and it will still work (in coming release). However, auto-claim is a form of authentication, so we need to know you're physically there, etc, so the app should be open.
Another feature coming in a release soon is Hog Mode, where you can turn auto-claim and auto-submit on for machines you own in a venue you own, which you turn on once when you press a special button at the start of a game. As long as games are less than 5 minutes apart, it will auto-claim and auto-submit for that machine. If you walk away and grab a beer and come back, it's like a kill switch, Hog Mode needs to be re-activated. This feature does auto-claim in the background, so the phone can go back in your pocket!
This is designed for home use, obviously.
