The 30 minutes between the moment participations are completed (21:30) and the moment that the draw starts (approximately 22:00) are necessary to secure every participation (slip) of the upcoming draw. 
More specifically: 

1. Every participating slip of the upcoming draw is locked in a file by a produced key number.

2. Then, the file is sent to the Independent Control Committee’s Computerized System. 

3. The Control Committee gives the final go to start the draw, only after all data is secured and every necessary procedure is made and verified.

A series of procedures take place in order to check and ensure credibility and transparency of the draws. The steps are the following: 

1. Draws are conducted in the presence of an Independent Draws Committee which consists of members who are defined by the Ministry of Culture. These members certify that every necessary procedure (a. final approval from Committee on Control b. test draws procedure) has been abided by to ensure the draw’s integrity. 

2. Before each draw procedure starts, drums and balls are checked by the Draws Committee (DC). Specifically, test draws take place for checking the drums and 2 of the 3 available balls strings are selected randomly by DC for the main and backup drums. Balls are weighted by a high accuracy weight scale, in order to certify that any weight deviations are within manufacturer’s defined margins. 

3. High accuracy weight scales, mechanical drums and balls are manufactured by internationally certified companies. 

4. Checking drums and balls procedure, as well as the live draw, can be watched by anyone interested. 

5. Draws are broadcasted live by a nationwide TV station – something that further ensures the procedure’s credibility.

For the security and control of the balls, a strict process is followed:

1. TZOKER balls are securely kept at the draws studio, in a specially secured area guarded by modern security systems, under optimum conditions, as they are protected from external climatic or human factors. 

2. The studio is monitored 24/7 through 16 security cameras, recording every move. 

3. Access to the safe-keeping area have only the authorized persons and the members of the Independent Draws Committee, appointed by decision of the Minister of Culture competent for sports.
