Different types of slot machines

Slot machines have a long evolution behind them. The first, fully mechanical slot machine was designed at the end of the 19th century by a San Francisco car mechanic, Charles Fey. The machine was a simple, three-reel slot with just five symbols on the reels, and could automatically handle payouts for all of its winning combinations. He didn’t know back then but he revolutionarized the gambling industry with his invention.

Later the slots have undergone several major changes – the first fully electromechanical slot machine was launched in 1963, followed by the first video slot machine in 1976, and the first online slots versions in 1994. The number of symbols, reels and paylines have all increased in the process – from five symbols, three reels and one payline to tens of symbols, up to twelve reels and over 100 paylines on some of the modern slots. Several types of slot machines are still in use at casinos, bot online and offline. Let’s see which are the most popular types.

1. Classic three-reel slots
These slot machines usually have three reels and a single payline. The player must decide how many units – coins or credits – he is willing to bet, pull the lever or press “spin” and wait for Lady Luck to smile on him.

2. Bonus slots
These are a more elaborate version of the classic slot machine – these machines offer bonuses for certain winning combinations on top of the winnings of the pay table. These bonuses can consist of free spins, nudges, bonus games and such.

3. Multi-payline slot machines
These are the best known and most popular slot machines available in online (and offline) casinos. These machines feature multiple reels and paylines – the most popular are the five-reel, 20-25 payline slots. The player gets to decide the amount to be bet on each payline and the number of paylines to be active for the next spin. Active paylines can be increased one by one, and the player also has the option to bet one unit on all of the paylines for the next spin. These games usually offer side games and bonuses to their players.

4. Progressive slot machines
These can be classic or multi-payline slots with different themes, shapes and sizes. All of these slots have one thing in common: they offer progressive jackpots (an amount that can be won in certain conditions that grows after each spin). Progressive jackpots are also of all shapes and sizes, from a few hundred to a few million dollars, depending on the progressive jackpot type (single, inhouse or pooled).

5. i-Slots
The i-Slots are a special kind of slot machines, introduced by Rival Gaming. These machines combine features of the multi-payline, multi-reel slot machines with elements of video games and movies to give its players an interactive and immersive gaming experience.
