When choosing from thousands of options, it's important to take a number of factors into account. An important factor to take into account is the game's Return to what is aviator gamePlayer (RTP) percentage, which shows how much a player can typically win back over time. For example, the theoretical return on a slot machine with a 96 percent RTP is $96 for every $100 wagered. Although this number cannot be guaranteed for specific sessions, it offers a helpful standard by which to compare various games.
