I have a trick to block all ads that come between apps and games. Including the video ads.It is completely safe. But it needs Android 9 (Pie) or above.
1. Open Settings.
2. Click Connections.
3. Click More connection settings.
4. Click Private DNS.
5. Click Private DNS provider hostname.
6. Enter the text: dns.adguard.com
7. Click on Save.
Now it will block all the ads that come between apps and especially, the games.
