Abstract: Maintaining the integrity of a virtual currency and by reducing the impact of hacking and otherwise fraudulent manipulation of an electronic game, and thereby encouraging end users to use freemium model software, may include managing the distribution of virtual currency giveaways. In some embodiments, virtual currency may be distributed in a secure manner by a server. In addition, user interest also may be maintained by providing unique features such as a double-up mini-game that allows a user to wager an amount won on a winning slot reel spin. The user may select one of two options and either win or lose the amount wagered. In some embodiments, a user may wager more or less virtual currency by applying a multiplier to the amount won on the winning slot reel spin. In addition, user interest may be maintained by integrating story elements into the one or more themed slot games.
