We would be wasting your time if we attempted to categorize all the types of slot machines. Every casino offers a wide variety 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, best online gambling site to mention just some.

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

Number of Reels

You will discover 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.
