Although it was possible to get free Wooz via a variety of methods in the past, the only way to currently get Wooz is through in-game purchases. Wooz is a form of in-game currency for "Woozworld," which is a massively multiplayer online game.
In the past, it was possible to trade Wooz, but due to people abusing this, Wooz can no longer be traded. Instead, "Woozworld" players must purchase Wooz with real-world currency. There are many ways to purchase Wooz, which include gift cards, VIP packages and Wooz Packs.
For more information on obtaining Wooz or for more information on "Woozworld," see Woozworld.com.
