In order to earn bling, you could participate in contests by playing games including Step Up Twix and Hide & Seek, and participating in costume and trivia contests. You could also receive five bling for logging in daily.
On January 27, 2013, the Bling Shop opened up to the public. Common things to spend bling on were clothing items and in-game features.
Bling is currently set to return in the 2017 version of the game at a later date after the opening, as stated by Twix.
