Google only allows certain countries to download games, so you might be in one of these countries preventing you from playing the game directly using your browser (or using any apps).
But there is still a way for you to play this game without having to face any errors again. All you have to do is disable your location/IP address by following these instructions below;
1- Make sure that both of your wifi or mobile data are turned off completely.
2- Now enable both of them again but don't connect to any of them as well.
3- Go into your wi-fi settings, search for a new connection, and then select 'yes' when asked if you want to create a new relationship.
4- Choose the network that is NOT yours from the list.
