Types of Slot Machines


Slot machines can accept either coins or paper tickets with barcodes as a form of payment. When you put your money into a machine, it spins the reels and the winning combinations are credited based on the paytable. There are a variety of different slots, each with a unique design, symbols, and bonus features.

Coin-operated slot machines

Coin-operated slot machines have been around since the 19th century. They were first developed in San Francisco by Charles Fey, a mechanical engineer. Fey’s machine operated by spinning reels and levers. He built thousands of machines for casinos around the world, including many that are still around today.

Three reel machines

One of the most popular types of slots is the three-reel machine. These games have three reels with two rows on each, although the latter sometimes has only one payline. When you spin the reels, you get a chance to win a prize based on the payback percentage, the number of paylines, and the symbols you see on the screen. The higher the payback percentage, the higher your chances of winning. Moreover, three-reel machines are much cheaper than older versions. For example, some of them only cost pennies per spin.

Video slot machines

Video slot machines are similar to traditional slot machines, but they use a video image instead of rotating reels. The video image is projected onto the screen, and its size and speed are determined by the number of coins you wager. This makes it possible to place larger bets than traditional slot machines.

Hand pay

Hand pay is a condition where a slot machine cannot pay out a patron’s winnings in the usual fashion. Instead, a casino employee pays the customer manually. This condition can occur in coin in and coin out systems. The coin out mechanism may not work properly, or the patron may have to use a large number of coins.

Virtual stops

A virtual stops slot machine uses a random number generator to determine winning combinations. Each virtual stop is equivalent to a slice of the pay table. When a winning symbol appears, the virtual stops are triggered and the reels stop drawing. This makes the virtual stops slot machine very convenient for players who are not sure about playing with real money.

Payback percentage

Payback percentage is the percentage of your money that comes back to you when you win a jackpot on a slot machine. Generally, it ranges from seventy-five percent to ninety-four percent. The higher the percentage, the better. For example, a 94% payback machine should give you ninety cents for every dollar you wager, while a five percent payback machine will only give you 25 cents for every dollar you bet. A high payback percentage means that you will have a better chance of hitting the jackpot.
