Technologies are described for generating random data. In some examples, a gaming device may include a game execution module, an extraction module, and a data generator. The game execution module may be configured to provide at least one player with a gaming service by continuously determining a plurality of parameters associated with the at least one player in a game operated by the at least one player. The extraction module may be configured to extract individual parameters from the plurality of determined parameters, the individual parameters having decorrelation with each other from a probability distribution perspective. The data generator may be configured to generate data items based on one or more of the extracted individual parameters, the data items being the extracted individual parameters or results of processing performed on the extracted individual parameters.
