I guess that you have heard about a game where you tell your partner a town name and he has to continue by saying another town's name but starting on the last letter of the previous one. For example:
London - New York - Kirov - Vaduz - Zürich - Helsinki ...and so on.
So I decided to recreate this game but with Names of countryballs that exist on this wiki. Before commenting check if this countryball has a page on the wiki. Do not put the "ball" suffix so we will avoid confusion & try to use well-known countryballs, otherwise - provide a link. Icons are recommended. Try to not repeat the countryballs.
