Types of Slot Machines


Slot machines come in a variety of forms, from coin-less machines to ones with multiple paylines. They can even have bonus features. In this article, we’ll look at some of the different types of slot machines, including those with bonus games and progressive jackpots. If you’re looking to buy your next slot machine, you should be aware of the different options.

Machines with no coin slots

Machines with no coin slots first appeared in 1909, and they were a response to the opposition to slot machines from morality and the clergy. Opponents claimed that slot machines were immoral and amoral. To combat these criticisms, Fey and his competitors developed machines that had no coin slots at all. This allowed the purchase and payout to be done across a saloon’s counter. Eventually, these machines became popular and factories for slot machines relocated to Chicago.

Coin-operated machines first came on the market in 1888. These early machines dispensed coins as they were inserted, but were prone to tipping. The coins were also likely to spill onto the internal balance scale. Later machines featured a circular display and a spinning indicator that pointed to a picture, colour or number.

Machines with progressive jackpots

There are several benefits of playing a slot machine that has a progressive jackpot. A progressive jackpot means that if a player wins the jackpot, their winnings are automatically increased by a certain percentage. This makes the machines a great choice for those who are looking for a chance to win large sums of money. However, players must be aware of the disadvantages of a progressive jackpot.

One disadvantage of progressive slots is that they do not reveal the odds of winning each jackpot. There are several types of jackpots, including mini jackpots, major jackpots, and mega jackpots. There are three main types of progressive slots: standalone progressive, mystery, and multi-level jackpots. Each of these categories has a different jackpot amount.

Machines with bonus features

Slot machines with bonus features help to break up the monotony of spinning reels and are usually activated by specific symbols. During these bonus games, you can win additional cash or free spins. Before playing any slot game with a bonus feature, you should first check its paytable. Some have one bonus game type, while others offer several. For instance, some slot machines offer free spins while others offer two or more different bonus games.

Another type of bonus feature in slot games is the buy a bonus. This feature involves betting a certain amount of money, often 50 to 150 times your stake, to buy a bonus trigger. Buy-a-bonus features are also common in slots, and they can be used to purchase better modifiers or additional free spins.

Machines with a high variance

Slot machines with a high variance are those that have large gaps between the highest and lowest payouts. For example, a payout for a three-of-a-kind combination will be 6x higher than a payout for a five-of-a-kind combination. This makes it highly unlikely that you will hit the next level very often. A high variance slot machine also has a much greater difference between the jackpot and the second-best prize. This difference can make it counterproductive to bet the maximum.

The best type of slot machine for you depends on your bankroll and the amount of time you have to spend playing. For a small bankroll, you should play a low variance machine. For a larger bankroll, a high variance machine will be better for you.
