Methods and systems for providing a virtual leash and command download capabilities on a hand-held personal gaming device (“PGD”) are disclosed. A host gaming system includes a game server configured to generate game seeds having data regarding predetermined game outcomes for various wager based games, and an authentication server configured to establish a virtual leash with a PGD. The virtual leash is adapted to repeatedly authenticate or verify a PGD user, a PGD location, the PGD itself, and/or software codes on the PGD. Included within an associated PGD are a display adapted to display gaming related information, a processor configured to execute gaming related code, and a memory containing a command download of computer code to be executed by the processor. The command download of computer code includes enough code for the PGD to process and display independently a game play based on a game seed.
