We'd be wasting your time if we attempted to categorize all the types of slot machines. Every casino offers a broad range of slots to attract gamblers. Slots come in hundreds of types and variations, from single line and 3 line, to 3 or 5 reel, and from bonus games to progressives, to mention just some.

It makes more sense to look at the standard characteristics of slot machines.

Number of Reels

You will find usually 3 or 5 reels in a slot machine. Early slots had only three reels. We remember them as "classic" or "regular" machines.

Today, 5 reel slots are common, and they generally feature more than one payline (see below).

Range of Rows

Slots machines feature one, two or several horizontal rows marking positions on the vertical reels.
Extra rows, usually one above and one below the payout display, tempt players with a view of how narrowly they might have missed a win.

Range of Pay Lines

There may be one or more paylines crossing the reels. It's common to determine 3, 5, 9, 15 and even more recently even 20 lines. For a winning combination, the designated symbols must fall on a line, often the central horizontal line.

There's only one payline crossing the three reels on a classic machine. You may bet one or more coins per spin but only the center line pays, and increasing your bet doesn't enhance your prospects of winning.

On a slot with more than one payline, you may bring additional lines into play by upping the range of coins you play. You should not have to bet on every available payline.

Suppose you are on a 3 line slot and you're necessary to insert one coin to play the center line, a second coin to play the line above center and also a third coin to play the line below center. If you now bet just one coin and also the reels display a winning combination on the line above or below the center, you do not win anything because you played too few coins.
By offering diagonal matches, slots with 5 reels may have information from physiotherapy.tagoremch.edu.in 5 to 20 paylines.

Denomination of one coin

You will find slot machines which accept denominations from as little as 5 cents to $5. High roller slots may accept "coins" with a denomination of as much as $500, although these are few and far between. Some online casinos have special limits setup for their big players to accommodate large bets..

Number of coins that may be played

The maximum bet on classic slots is usually three coins, but you will find some slots that accept a 2-coin maximum bet. Again, video slots have changed this characteristic dramatically, with some multi line video slots now accepting up to 10 coins per line.
