If you've been spending time on the FallnAngel sims recently, looking for Ostara eggs, you might have been lucky enough to win one of the random prizes on offer.
As it's a random prize giver, you have absolutely no control over how, when, what or if you win :)
However, it does dish out prizes every 15 minutes in the FallnAngel Creations mainstore and Sanitarium ('ware zombie attack) sims.
Other great freebies/prizes at the Falln mainstore include *deep breath* a what's in the box prize, lucky chair and/or midnight madness on almost every floor of the mainstore, and a daily pressie rezzer.
You have to hunt for the daily pressies, but a pile of coloured boxes usually aren't too hard to find. (Remember not to give the location of the pressies in local chat!)
