Too many notifications from an app

Hi friends, I play a game (Dominoes) on my iPhone with several different friends, and each friend and I may have multiple games going at once. It generally takes about 3-10 seconds to make a move, and after each move, I get the notification that my friend has played. This means that I may get a notification every 3-10 seconds, depending on how many friends are playing and how many moves they’ve made. This is extremely annoying, as you may imagine. I have Immediate Delivery scheduled and Notification Grouping by App, but I’ve just changed it to Scheduled Summary and enabled Show Next Summary in the hopes that I’ll get a single notification periodically instead of every few seconds, though the summaries will only happen at 08:00, 12:00, 18:00, and 21:00 unless I add more schedule times.

Is there a better way to configure these notifications so that I only get one notification, maybe every 15-30 minutes no matter how many moves have been made?

Thanks!

I think that the app would have to be deigned to support notification options like that. It sounds like scheduled summary is the best bet, or perhaps turn off banners and depend instead on looking at notification center for updates.
