Claim:
A method of detecting unusual performance in a game, the game having a plurality of persons who participate in the game, each on a client device, the method comprising: broadcasting game elements during the game from a server to each client device participating in the game; selecting a sampling group of persons participating in the game, the sampling group comprising a subset of all persons participating in the game; forming a connection between each client device used by the persons within the sampling group and the server to send responses to the game elements from the client devices of the sampling group to the server; utilizing the responses received from the sampling group at the server during the game to determine a distribution of results and a threshold value for the game; broadcasting from the server to each client device participating in the game the distribution of results and the threshold value; calculating for each person participating in the game a performance metric at the client device, the performance metric corresponding to the person's performance in the game; comparing at the client device the performance metric to the threshold value thereby forming a comparison; and based on the comparison, for each person participating in the game not in the sampling group, optionally forming a connection to a server for uploading a set of data from the person's client device to the server.
