Decentralised draw systems (DDS)

The Office of Liquor and Gaming Regulation (OLGR) Queensland has developed the concept of a decentralised draw system (DDS). The DDS concept is based on having multiple draw participants (random number generators) communicating with each other. Each of these contribute sufficient random outcomes, which are securely combined to produce the final draw result. DDS have the potential increase draw security and reduce operating costs in the long term, however, the document is for discussion and concept development purposes only. It is not Queensland Government policy, nor is it a technical requirements document. We welcome your feedback by email to the Gaming Services Branch Technical Unit at or phone 13 QGOV (13 74 68).
