On December 1, 2020 surprising draw results raised attention world-wide. The numbers drawn in the December 1st Powerball drawing were: 8, 5, 9, 7, 6, in this order, and the Powerball number was 10. When sorted from lowest to highest, these numbers created a sequence 5, 6, 7, 8, 9 and 10 which raised general suspicion of foul play. These concerns were quickly addressed and the validity of the draw was attested to by ITHUBA and recognized by the South African National Lotteries Commission. The validity of the draw relies on the unique properties of the Trusted Draw™ Random Number Generator (RNG) system, that verifies the integrity of each and every draw.

We explain below: (1) how draw integrity is ensured by Szrek’s RNG method, (2) the reason for many winners, and (3) the statistics behind draw patterns.

1) Draw integrity: a unique feature of Szrek’s patented RNG technology is that it enables verification of the specific draw numbers (US patent # 6,934,846) and detects 100% of draw hardware faults and software fraud. The technology which is based on nonrepudiation also allows for proving the integrity of legitimate, even if surprising, combinations. For each draw, the Trusted Draw™ RNG system creates proof of integrity which is then verified by an independent Trusted Audit™ system. This verification confirms the randomness and authenticity of the draw numbers. Also, the Internal Control System (ICS) automatically verifies with Trusted Audit the draw numbers used by the gaming system, attesting to their validity. The Szrek RNG has been certified over 25 times by numerous independent labs, including Gaming Laboratories International (GLI).

The Powerball draw of December 1st 2020 was verified by ITHUBA Officials and their Independent Auditors using Trusted Audit. Szrek2Solutions also verified the results after the draw had taken place. The draw verified correctly – all draw reports on the draw and audit systems were identical. Such verification allows us to confirm that there were no hardware or software issues and that all the numbers were drawn properly.

“It was verified for its correctness and randomness, so we can warrant the integrity of this draw. Any independent entity, such as a regulator or external auditor, with access to our Trusted Audit technology can verify the integrity and randomness of all draws,” said Irena Szrek, CEO of Szrek2Solutions.

2) Many winners: there were more winners than usual because the winning numbers formed a pattern. People play numbers in patterns more often than any other numbers. These patterns include consecutive numbers, series, geometrical patterns on the bet slip, birthdays, etc. A normal consequence of the pattern in the winning numbers is that there are more winners.

3) A Statistical Analysis: both Powerball and Powerball+ (another draw game with the same matrix) have been played twice a week in SA over a period of a few years. The probability of having a sequence of 5 numbers from 1 to 50 occurring once in a year is approximately 1 in 222 and with the Powerball (1 from 20) occurring as the 6th number in the sequence, the probability is 1 in 13,497. Over six years of playing the two games, these probabilities increase to 1 in 37 and 1 in 2,264, respectively. Note also that there would be a higher probability of the event occurring if we looked at all draw results that formed some type of a pattern that could be deemed ‘suspicious’ (e.g. if the numbers drawn are 2,4,6,8,10 or 5,10,15,20,25).

The likelihood of draw results forming a pattern should be considered not as a single event, but in historic and geographic context – as an event in a global lottery environment. Over the years, an event like this will occur.

“Unlikely number sequences can and will occur, and recognizing the importance of integrity and transparency, ITHUBA selected an RNG system that enables us to prove the integrity of the draw numbers to our players,” said Busisiwe Msizi, ITHUBA’s spokesperson.
