In 776 BC the concept of sports betting was born in Ancient Greece. At that time, several types of competitions were played: the Olympics, the Phytic games in Delphi, the Isthmic games in Corinth or Nemea, and various people bet on these events from the desire to earn money easily. Thus, after the end of the Roman era, the betting method was also transmitted to the Middle Ages during the tournaments. The noblemen trained their servants about the strategy and the amounts they would bet, and the win was entirely for the nobles. Beginning with the 17th century, especially in 1780, sports betting developed a lot in England and the great revolution in the field of sports betting began; given this, we can say that England is the founder of sports betting even though it has existed since Antiquity. Sports bets are played around the world, but in Europe they have the biggest impact, also having a major tradition of doing so. From a different point of view, bookmakers are organizations that publish odds, analyse various sports events, accepting sports bets from bettors and incurring all their losses, and the need to offer certain amounts if the bettor wins the bet. Betting tickets can be simple or combined. The simple ones contain only one event and the combined ones may contain more events. They also have different peculiarities that can be played in a predefined or combined system, and in order to win, all events on the ticket must be winning. Combined bets are used if you want to earn a higher amount with a small investment.
