How to Find the Best Bonus Features in Slot Machines


If you have ever played a slot machine, then you’ve probably noticed the bonus game. These games are almost always random and involve choosing from a treasure chest, box, or video display. Unlike video games, however, you don’t need to be good at picking which ones to pick. Designers of slot machines are increasingly incorporating elements of video games into the design. For example, a bonus game may be triggered by a certain number of symbols on a reel, or it may be triggered based on the amount of aliens shot.

Modern slot machine design

Today’s modern slot machine design is aimed at increasing the number of bets per customer and encouraging prolonged, faster play. Computers, such as those found in casinos, are much more efficient at designing games based on random numbers than their mechanical predecessors. Modern slot machines take both coins and credit cards and process hundreds of bets per minute. A MIT anthropologist studied the psychology of gambling and discovered that a slot machine that offers a slow, recurring series of small wins is more likely to encourage repeated bets and long “time on machine” sessions. Low rollers, in particular, are attracted to this slow ride, which ensures a gradual loss.

The process of random number generation, which determines the outcome of a slot machine’s reels, was developed by Inge Telnaes in the late 1970s. Bally and Universal were the first major manufacturers to incorporate this method. This RNG-based system uses a stepper motor to stop the reels exactly where the computer tells them to stop. Today’s slot machines use a computer inside the machine to determine the outcome of each spin.

Bonus features

There are dozens of different types of bonus features in slot machines. Some feature free spins, while others offer sticky wilds or cascading reels. Bonus features can also trigger a mini-game, which can add extra spins to your bankroll. Whether you’re looking for a simple way to boost your bankroll or want to win a jackpot, bonus features can make the difference between a mediocre game and a great one.

Aside from the special symbols, you can find many different bonus features in slots. Some of these include free spins, scatters, or jackpots. Others will grant you free spins or a chance at a progressive multiplier. All these extra features increase the chance of winning.

Traditional slot machines typically have horizontal paylines. However, online slots can also feature many rows. For example, there are vertical paylines, and horizontal paylines. Some online slots even have no paylines at all! To win, symbols must align on all five rows to make a win. The more paylines you play, the more complicated the game becomes. It can also become difficult to understand the game and reduce player interaction. Therefore, make sure you understand the rules of the game before choosing a particular machine.


Since 1895, when Charles Fey invented the first three-reel slot machine, slots have been an extremely popular game in casinos. The early slots didn’t always pay out money, though, as they often gave out bubble gum or other prizes. The house win percentage was around 8 percent, but by 2021, most casinos expect payout rates to fall to 87 percent. This trend is expected to continue, with over three-quarters of all jobs in the United States expected to be automated by this time.

The state regulates slot machine payouts. There are no set payout limits, though many state regulators may not have any. The percentage of payouts varies widely, but the casino is in charge of ensuring fair play. While slot machines are programmed to pay out a certain percentage, you might encounter “hot” or “cold” streaks. This is due to the fact that a random number generator can’t alter the outcome of a spin.
