Guaranteed Lottery Prizes<\/h2><\/div>\n\n\n\n

Most of the biggest and most popular lotteries on TheLotter have some form of prize guarantee. Take EuroMillions, for example. The EuroMillions jackpot<\/a> starts at \u20ac17 million<\/strong>, which means that there is a \u20ac17 million<\/strong> guaranteed jackpot. The pan-European EuroJackpot lotto<\/a> is similar, with a guaranteed minimum jackpot of \u20ac10 million<\/strong>.<\/p>\n\n\n\n

When you play Powerball<\/a> or buy tickets for Mega Millions<\/a>, there is a guaranteed second prize of US$1 million<\/strong>. The rest of the prize categories are guaranteed, as well. In both Powerball and Mega Millions, it is possible to add a multiplier option that will vary depending on the draw and ticket sales, although it is still fair to say that the secondary prizes are guaranteed because the minimum winning amounts are fixed. Although you may wonder if there are any tips for winning the Powerball jackpot<\/a>, winning a second prize is also quite satisfactory!<\/p>\n<\/div>\n\n\n\n

Pari-Mutuel Jackpots<\/h2>\n\n\n\n

If you have never read the fine print of a lottery, there is a good chance that you have no idea what these words mean. That\u2019s ok, we\u2019re here to tell you. Pari Mutuel is French for \u2018mutual betting.\u2019 The concept originated in France in the 1870\u2019s for betting on horseracing and other sports, but is applicable to the lottery, as well.<\/p>\n\n\n\n

In a Pari-Mutuel lottery system, revenue from ticket sales is divided amongst the prize categories; there are no fixed prize amounts. EuroMillions is an example of a Pari-Mutuel lottery. Each prize category, from the jackpot down, receives a percentage of the overall ticket sales. There are no fixed prize amounts except for the guaranteed starting jackpot.
US Powerball and Mega Millions also fit into this category. Each offer jackpot prizes that are calculated on a Pari-Mutuel basis, meaning they’re determined by ticket sales and interest rates. Both start at an estimated US$20 million<\/strong>.<\/p>\n\n\n\n

Another important feature of Pari-Mutuel lotteries is that winners in a prize category split the prize equally. If five people win a 3rd prize worth US$50,000<\/strong>, each person wins US$10,000. This is the complete opposite of a guaranteed prize because the amount a winner will take home depends on how many other winners there are, as there is no guarantee.<\/p>\n\n\n\n

Pari-Mutuel vs. Guaranteed Prizes<\/h2>\n\n\n\n

Which system is better, Pari-Mutuel or guaranteed? The truth is that there is no right answer. A guaranteed prize is just that, you know exactly what you will win regardless of how many other people draw the same numbers and therefore win the same prize.<\/p>\n\n\n\n

Pari-Mutuel systems have a lot more fluctuation in both prize amounts and winner amounts, depending on ticket sales and the amount of winners.<\/p>\n\n\n\n

Sometimes Pari-Mutuel comes out ahead of guaranteed, sometimes it doesn\u2019t. However, because of the variability inherent to the Pari-Mutuel system, it keeps lottery players on their toes. It is definitely worthwhile to pay attention to prize amounts.<\/p>\n\n\n\n

Progressive Jackpots<\/h2>\n\n\n\n

A progressive jackpot is one in which if the jackpot is not won, it will carry over and grow for the next drawing. Most lotteries feature a progressive jackpot and sometimes secondary prizes, as well.<\/p>\n\n\n\n

The US$1.586 billion<\/strong> US Powerball jackpot is a perfect example of a progressive jackpot in action. Rollover after rollover, the jackpot grew until three lucky winners claimed the record-setting prize.<\/p>\n\n\n\n

EuroMillions, on the other hand, has a jackpot cap of \u20ac240 million<\/strong>. Once the jackpot reaches the cap, it cannot grow any larger and money from ticket sales that would be added to the jackpot is added to the second prize category instead. Although, until the EuroMillions jackpot reaches its cap, it is progressive.<\/p>\n\n\n\n

The exciting daily lottery New York Take 5 is an example of a Pari-Mutuel lottery with a non-progressive jackpot. If no one wins the jackpot in any given draw, it does not roll over and grow. Instead, the jackpot amount is added to the next prize category in which there is a winner. The winner or winners in that category then share the whole amount, the original amount plus the jackpot amount, evenly.<\/p>\n\n\n\n

Putting it All Together<\/h2>\n\n\n\n

You might come across these terms if you read the rules or fine print of a lottery. These terms are good to know and understand as they will help you understand more about the many different lotteries on TheLotter. Pushing beyond the jackpot, which rightfully gets a lot of attention, and understanding how lotteries are designed and work is not only fun and rewarding, but can also give a player excellent insight into which ones are the best games to play.<\/p>\n\n\n\n

One important thing to remember is that these terms are not mutually exclusive – a lottery can be Pari-Mutuel, with a progressive jackpot, yet have guaranteed prizes. Or, pretty much any other combination of the above. It is always possible to find \u2018ifs\u2019, \u2018buts\u2019, and caveats in the rules of any given lottery. That is one of the things that makes playing the lottery so exciting!<\/p>\n\n\n\n
