Two machines are used in each Mega Millions drawing. The model used for Mega Millions is the Criterion II, manufactured by Smartplay International of Edgewater Park, New Jersey. The balls are moved around by means of counter-rotating arms which randomly mix the balls. Individually, the five white balls, several seconds apart, drop through a hole in the bottom of the mixing drum.
The 2015 changes extended the main ball pool to 69 balls, adding another ten numbers. However, at the same time, the Powerball pool decreased from 35 to 26. This means that although the overall odds of winning the jackpot have increased to 1 in 292 million, the overall odds of winning any prize have decreased to 1 in 24.87. The first draw incorporating the changes took place on October 7th and also saw an increase in the tier three prize (matching 4+1) climb to $50,000.
