Device, system and method of gaming. For example, a method of operating a game includes: based on a received pre-paid amount, assigning to a user a subscription period and a substantially unlimited amount of virtual game-related operations that the user is permitted to perform during the subscription period; virtually performing, during the subscription period, game-related operations in response to commands received from the user during the subscription period; after the subscription period elapses, calculating a profit-and-loss balance of the user based on the game-related operations virtually performed for the user during the subscription period; and if the profit-and-loss balance is positive, assigning to the user a prize calculated based on the profit- and-loss balance.
