Since the secondary prizes are defined in fixed amounts (except in California), if the liability for a given prize level exceed the funds in the prize pool for that level the amount of the prize may be reduced and the prize pool be distributed on a parimutuel basis and result in a prize lower than the fixed amounts given in the prize tables. Because the secondary prize pools are calculated independently, it is possible lower-tier prizes will differ among the game members.
Lottoland is not an official lottery operator and does not buy any lottery tickets on your behalf. Instead, Lottoland allows you to make bets on different lotteries. If you win any bets, then you get paid directly by Lottoland and not the official lottery operator. All jackpots are estimates and subject to currency fluctuations. *Tier 1 winning bets on the US Powerball and US MegaMillions are paid out as 30 year annuity or discounted lump sum at Lottoland’s election, and Tiers 1 – 3 are also subject to 38% reduction as per T&C's. Tiers 1 - 3 for winning bets on SuperEnalotto are subject to 12% reduction as per T&C's.
The probability and odds can be taken into a mathematical perspective: The probability of winning the jackpot (through October 27, 2017) was 1:(75C5) x (15); that is: 75 ways for the first white ball times 74 ways for the second times 73 for the third times 72 for the fourth times 71 for the last white ball divided by 5 x 4 x 3 x 2 x 1, or 5!, and this number is then multiplied by 15 (15 possible numbers for the "Megaball"). Therefore, (75 x 74 x 73 x 72 x 71)/ (5 x 4 x 3 x 2 x 1) x 15 = 258,890,850, which means any combination of five white balls plus the Megaball has a 1:258,890,850 chance of winning the jackpot. Similarly, the odds for second prize are 1:(75C5) x (15/14) = 1: 18,492,204 chance of winning. The overall probability of winning any prize was 1 in 14.7. If there are no jackpot winners for a specific drawing, the jackpot will keep increasing, however, the odds will still remain the same.
Under the current version's regulations (which began October 28, 2017 with the first drawing October 31) for Mega Millions, the minimum Mega Millions advertised jackpot is $40 million, paid in 30 graduated yearly installments, increasing 5 percent each year (unless the cash option is chosen; see below for differences by lotteries on cash/annuity choice regulations.) The jackpot increases when there is no top-prize winner (see below for information on how the Mega Millions jackpot is funded.) As of December 13, 2017, there has yet to be a jackpot winner under the current Mega Millions format, including wagers for the newly created Just the Jackpot option.
The structure of the draw is one which regular lottery players will be very familiar with; players must pick 5 regular numbers from a pool with a total of 69 numbers and in addition to these regular number picks, you also choose one bonus ball (known as the Powerball) from a pool of 26. These two pools of numbers are mutually exclusive and remain completely separate throughout the drawing procedure. In order to jackpot the US Powerball, you need to match all 5 regular numbers and the Powerball. Do this and you are instant Powerball millionaire – it’s as simple as that!
