Decentralised draw systems

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 to increase draw security and reduce operating costs in the long term, however, Decentralised Draw Systems (DDS) - Version 1.0 is for discussion and concept development purposes only. It is not Queensland Government policy, nor is it a technical requirements document.

For full details, read OLGR's Decentralised Draw Systems (DDS) - Version 1.0. We welcome your feedback by email to the Gaming Services Branch Technical Unit at or phone 13 QGOV (13 74 68).
