  • Game parameters GP are the game rules under which game indicia may be combined to form winning combinations on an instant gaming ticket. For example, the game parameters for an instant game may require that winning combinations of game indicia are sets of identical game indicia uncovered in the play area of the instant gaming ticket. Information about the instant game and the ticket itself may be used in a scheme for validating and authenticating an instant ticket.

Abstract

L'invention concerne un dispositif et un procédé de validation d'un ticket de jeu instantané. Ledit ticket comporte en impression des données de validation et des informations de jeu, ces informations de jeu étant recouvertes d'un revêtement opaque amovible, et une partie des informations de jeu n'étant pas recouverte en conformité avec une règle de jeu pour la pratique du jeu. Le ticket instantané est lu afin de déterminer les données de validation et les positions relatives des informations de jeu non recouvertes sur le ticket instantané. Des données de jeu concernant le ticket instantané sont obtenues d'une position différente de celle du ticket instantané. Un ticket virtuel correspondant au ticket instantané est créé sur la base des données de validation et des données de jeu. Le ticket virtuel est comparé au ticket instantané afin de déterminer si une combinaison gagnante des informations de jeu est découverte sur le ticket instantané en conformité avec les règles de jeu. L'invention concerne également un dispositif et un procédé de fabrication d'un tel ticket instantané.
