I'm sorry, I already spent a lot of money for Google Maps API in that month. So I disabled billing, and the map looks a little bit strange. But all games are still working properly. Any Patreon donations helps me.
Here, in the form of a game, you can learn the names as well as locations of each country or a state while having fun doing it. To begin the game, select a region from the map or the list and look at its flag, coat of arms and perhaps, even more information to help you learn geography. after Registration, you can create your puzzles from more than 100,000 regions!
This is a non-profit project, but servers and other resources are not free for me. Please consider supporting the project on Patreon.
