There is no way to win at the game "SmallWorlds." It is an online role-playing game with no winning conditions; instead, the point of the game is to socialize and integrate online content from other sources into the game world.
There is an official blog post from the developers titled "How to WIN on SmallWorlds," but this does not detail any way to win the game. It is a list of general tips on how to avoid scams from other players. These tips focus on curbing currency and item theft and on ensuring that players know the only legitimate way to purchase in-game currency is through the official website.
