Online slots can be classified into three broad groups. The first group is 3 Reel Slots, also known as Classic Slots. These slots have three reels and usually include symbols reminiscent of the earliest mechanical slot machines like fruit symbols or bars. The Video Slots group is the most widespread. They have 5 reels and are characterized by animation and sound effects and other fancier features. The Progressive Slots can have either 3 reels or 5 reels. They differ from the earlier groups in the nature of the jackpot. In 3 Reel Slots and Video Slots the amount of the jackpot remains fixed and is determined by the payout table. In Progressive Slots each wager adds to the jackpot amount, which keeps growing till it is hit.

Yet they are more popular than both blackjack and video poker put together. In fact they are by far the most popular online casino games. The popularity largely lies in the life changing payouts, particularly in progressive jackpots. It is enhanced by the magic of the special effects and the bonus features that online slots routinely offer.
