Abstract
A lottery ticket has a covering scratch-off coating applied over at least part of a game area, including game data applied over an ink layer including a lily pad. A detectable taggant additive material is admixed in an ink of the ink layer having the characteristic of being detectable by a detection scanner when applied over the substrate where the covering scratch-off coating masks the ability of the detection scanner to detect the detectable taggant additive material through the covering scratch-off coating. The scanning of the game area is used to detect areas where the scratch is removed in order to confirm that the game has been played or to detect patterns of removal in a probability type game.
