I emailed them Sunday after they had 10 in-a row. This is their response.
Dear XXXXXXXX
Thank you for writing the Florida Lottery. In response to the question you presented in your e-mail, "We aren't doing pre-tests, then using the one with least payout." All the Florida Lottery On-line games (CASH 3 - PLAY 4 - MEGA MONEY - LOTTO - and FANTASY 5) are of a chance nature and there are no manipulating of drawings to pre-select certain groupings. When dealing with numbers, especially with such a limited range (000 through 999) one can expect some of the most unusual groupings to occur. However, all of our Florida Lottery drawings are held to the highest security standards and are audited by an independent external auditor.
All of our On-line game drawings are televised live from studios in Tallahassee. If you would like to request permission from our Division of Security to view one of the drawings, you should submit your request in writing to:
FLORIDA LOTTERY -- Division of Security -- 250 Marriott Drive -- Tallahassee, FL 32399
Please be sure to include your name, date of birth, and social security number along with a copy of a photo ID. They will respond directly to you. Thanks again for writing and best of luck in the games.
