L'ordinateur de jeu comprend un logiciel de jeu (22) offrant au joueur la possibilité de parier et lui permettant d'obtenir un crédit de jeu et de toucher ses gains. L'ordinateur central (30) permet au joueur d'acheter et de faire valoir des crédits de jeu au niveau de l'endroit éloigné au moyen de protocoles cryptographiques et par une série d'échanges de messages authentifiables entre le joueur et l'établissement, ou par connexion directe entre l'ordinateur de jeu et l'ordinateur central. Selon une variante, l'ordinateur de jeu comprend un module de crédit amovible et inviolable qui lui est associé ou qui peut être utilisé avec un ordinateur personnel attribué au joueur avec un crédit de jeu préchargé.
