We would waste your time trying to categorize all types of slots machines. Each casino offers many different types of slots in order to attract gamblers. There are many variations to slot machines. They come in single, three, or five reel formats, as well as bonus and progressive games.

It makes sense to focus on the characteristics of slot machine machines.

Reels

In a standard slot machine, there will be 3 to 5 reels. Early slots had just three reels. We refer to them as "classic", or "regular", machines.

5 reel slot machines are now common. They often have more paylines (see below).

Numbers of Rows

Slot machines have either one, two, or multiple horizontal rows to mark positions on the reels.

The extra rows offer players an opportunity to see how narrowly they might have missed winning a prize.

Number of Pay Lines

It is possible to see multiple paylines across the reels. It's not uncommon to see three, five or nine paylines crossing the reels. A winning combination requires that the symbols be placed on a line. On a classic machine, there is only one payline that crosses all three reels. You can put one or more coins on a spin but only the middle line pays. This will not increase your chances at winning.

By increasing your coins, you can bring more lines to play on a slot that has more than one payline. You don't necessarily have to place on every possible payline. Imagine https://www.partneringforinnovation.org/ that you are on a 3-line slot. To play the center line, you must insert one coin. The second coin will play the line above it. The third coin will play the line below it. If you place only one coin on the slot and the reels display winning combinations on the lines above or below, you will not win anything.

With diagonal matches, 5 reel slots can offer 5 to 20 paylines.

Denomination one coin

Slot machines can accept denominations of 5 cents to $5. While high-roller slots might accept coins up to $500 in denomination, they are not common. Many online casinos have high limits to allow for large bets.

Number and type of coins that can played

The maximum bet for classic slots is three coins. But, there are some slots that will take a max of 2 coins. Video slots have seen this change dramatically. Some multiline video slots can now take up to 10 coin per line.
