While many of Zynga's fans are used to receiving daily reward emails from games like FarmVille or CityVille, CastleVille players can now get in on the fun as well, as those who are still signed up for the game's email newsletter will finally start receiving free items once per day just for continuing to be a member.
This Daily Rewards program offers you a choice of one of three rewards each day. You can choose the energy reward to be given an energy vial worth anywhere from 1 - 5 energy points, while the expansion reward offers you up to three Crystal Shards that can be used to create Expansion Crystals.
Perhaps the most interesting option is the mystery prize, as you'll be able to receive a "surprise gift" that may not be available anywhere else. For instance, you may open a mystery box only to receive a free Baby Zebra, an animal that isn't available to purchase in the game's store as of this writing. You'll be able to choose from these three options once per day, every day indefinitely into the future, so make sure to check your spam folder and start accepting these rewards to get ahead even faster in your kingdom!
What sorts of prizes have you won from the CastleVille Daily Rewards program? Do you think the Mystery Gifts are worth skipping over free energy? Sound off in the comments.
