International lotteries often differ from those in the United States in terms of structure, regulations, and prize distribution. Some countries operate national lotteries with a single governing body, while others have multiple regional games. Prize taxation varies widely, with some countries offering tax-free winnings, unlike the U.S., where lottery prizes are subject to federal and state taxes. The format of games can also differ, with certain international lotteries offering unique game styles or jackpot structures.
