Abstract
A gaming machine coupled to at least one server via a network includes a display device configured to display a game to a player playing on the gaming machine, and a controller coupled to the display device. The controller detects an award trigger during play of the game, and awards a token upon detection of the award trigger, wherein the token includes an activation date, an expiration date, and a value that is unknown to the player at the time of being awarded. In response to a redemption request by the player, the controller determines a redemption status of the token and, based on the redemption status, awards the token value to the player or notifies the player that the token is expired.
