Methods and systems that enable reliable audits of a number of predetermined trust requirements for games by electronic means, either on-site or remote, are disclosed. A system including a gaming module to which the players interact with a security module and an audit module capable of several degrees of dispersion and/or grouping performs provision by the gaming module to the security module of digital information containing significant events occurred during the games, generation by the security module of a protected record for each of the cited significant events, storage by the security module of every protected record, generating a file of protected records, and access by the audit module to the file of protected records, independent from the games operator, to verify the correct development of the games.
