Missouri Lottery Drawings

The Lottery’s computerized drawing system, which was implemented on July 20, 2020, uses technology to select the numbers for Missouri's in-state Draw Games (Lotto, Show Me Cash, Pick 4 and Pick 3).

The computerized system, named Origin (manufactured by Smartplay International, Inc.), is housed in a secure draw room in Jefferson City. These draw systems are not connected to the Internet or any other network source. The draw systems have no other phone or data lines from which to send or receive information.

The system is operated by a Lottery employee draw manager in the presence of an independent auditor. The system is designed to draw games in "Game Sets," which include all games to be drawn at either the Mid-day or Evening draw time. Each Game Set may only be drawn once per day and only within specific timeframes.

Only designated Missouri Lottery drawing personnel and an independent auditor are allowed in the room during a drawing. Every drawing is monitored by special motion-activated video cameras which videotape every action on the draw computers and in the drawing room.

Access to this room is further limited by secure keypad access that allows only designated draw personnel to enter the room. Furthermore, the Origin System used to draw the numbers is randomly selected from one of two identical systems prior to the draw. These systems require user-specific usernames and passwords. Consequently, only designated draw personnel will be able to login to the system to perform any drawing. In addition to the motion-activated video cameras in the draw room, all activity on the Origin System is electronically logged.

The Origin System continuously tests its Random Number Generators (RNGs) to ensure they are operating within acceptable parameters. These RNGs are connected to the system via the Random Number Server (RNS), which is not physically accessible to Missouri Lottery employees as it is housed in a locked chassis. An alarm system connected to this locked chassis will alert the Origin System if it detects a physical intrusion, and will lock the system down.

Gaming Laboratories International certified the Origin Systems equipment, components, and computer software which created “checksum” values providing the underlying security of the drawings. Before each drawing, these checksums are verified by both the Draw Manager and the Independent Auditor to confirm the continued integrity of the system’s software.

Lastly, the Origin System maintains logs and tables of data traffic and activity as it occurs. With this information, Missouri Lottery Security personnel are able to "reconstruct" any drawing that has taken place to confirm its validity.
