What You Need to Know About Payback Percentages, Symbols and Bonus Rounds


The mathematical expectations of a slot machine’s payouts are the basis for the game’s payback percentage. Real slot machines have more winning combinations but lower prize amounts. The total prize amounts multiplied by the probabilities of winning are less than 100%, or “payback percentage”. Modern slot machines, however, use the same math but computer programs to determine the payback percentage. This has both perks and disadvantages for players. Read on to learn more about payback percentages, symbols and bonus rounds.

Payback percentages

When you’re at the casino, you might be wondering what the payback percentages of slot machines are. This statistic reveals how much you can expect to win for each dollar you wager. In addition, it shows how much the casino will earn in the long run, or house edge, over the course of an hour or a day. High payback percentages are better than low-paying machines, since they enable the casino to recoup their costs. Many slots pay over ninety percent of bets, and those with lower payback percentages will make you lose at least 25 cents per dollar.


There are two main categories of slot symbols: standard and bonus. The standard ones pay out when a combination of three or more of them land on the reels. The special ones trigger bonus effects and sometimes pay out as well. You can also win by matching two or more special symbols in a row. The classic symbols include horseshoes, spades, and diamonds. They were used on traditional slot machines long before they were made popular in online casinos.

Bonus rounds

Bonus rounds on slot games have been around for a while. The earliest versions included Free Spins or Multipliers, but now they can also feature other types of player treats. Ninja Magic slot game combines Free Spins and extra wins. Players can choose to unlock bigger multipliers or additional Free Spins and win more. Bonus rounds are a great promotional tool for casinos and have become a staple feature of online casinos. But how can you find the best bonuses?

Random number generators

In fact, there is an edge to using random number generators for slot machines. Players know which symbols will pay, but they can’t predict when the machine will actually pay out. That’s because the number generators are completely random. This makes the slot machines more fair to players. Moreover, all new machines manufactured from now on will have random number generators. Therefore, winning at random number generators is not as easy as it sounds.
