This all depends on what you like! If you want to go for the biggest jackpots in the world, then US lotteries and the EuroMillions offer the largest prizes. However, with hundreds of millions of tickets sold, not only are the odds of winning low, but you may have to share the jackpot with other winning tickets. Many players enjoy some of the smaller state lotteries run in England, Spain, Germany and Italy, for example. These still offer huge prizes but have less players.
