You can disable push notifications on Android by going into the Settings > Notifications options. Similar to iOS, Android lets you turn off push notifications for individual apps or use a 'Do not disturb' mode.

1. Tap the "Settings" icon.

2. Select "Apps" (or Application manager).

3. Scroll down and select the Heart Bingo app.

4. Tap to uncheck "Show notifications" to disable push notifications for that app.

The best way to turn off notifications is to silence apps individually. You can do this from the Notification Shade as each notification appears or toggle each app individually all on one screen.
