Can I delete the ads from a game?

If you turn off your internet, you will not see any ads. If game needs internet, it's not possible.

you should install some ads blocker ads such as adguard, or you can install an adblocker server such as Pihole

If you are on Android, and it's not rooted, you can get Blokada DNS. It wont remove all the ads, but most of it. Otherwise if it's rooted, you can get any ad blockers that modify your hosts file.

You can't, But if you disconnect the internet then it is possible

root your phone get an adblock and clear your cache. There are no root adblocks available, just google around.

adblock program he google as if we'll find a little bit in the father, but it is difficult to block the games adblock program or intertnet for games need to close

For exemple, in candy crush, turn off your wifi and data and no ads :D

Maybe block them with a VPN? I know PIA has a setting for blocking ads

if the game requires internet to be played, download lucky patcher and patch tthe game so it has no ads in
