I've recently started playing paper.io 2. It's pretty fun. I don't really have any techniques yet. Apparently, you're always just playing against bots, which is weird because it feels like you aren't.

The app is available for download on the App Store and Google Play, and is rated for players aged 4 and up. Playing Paper.io 2 and other mobile games can have several benefits for kids, such as providing entertainment and enjoyment, and helping to improve hand-eye coordination and reaction time.
