Abstract
A lottery ticket is printed onto a conventional paper, card or similar substrate to provide game information printed on the substrate and game data printed on the substrate where some or all of the game data is covered by a removable covering which can be removed by the player generally by scratching a latex covering layer to expose the covered data for playing the game. In addition, a battery is printed on the substrate together with printed conductive paths, a powered element such lights or sound or a changeable ink formed on the substrate and a switch responsive to an action on the substrate by the player, generally scratching of the covering layer for conducting power from the battery to the powered element.
