Charles Fey built upon the Sittman and Pitt invention by adding three reels and replacing poker symbols with diamonds, spades, horseshoes, hearts, and liberty bells (hence the name “slot”). He also programmed the machine to weight particular symbols and thus increase the probability of winning. This greatly increased jackpot sizes and allowed for more combinations.

Slots in casino online games are designed to be as close as possible to their live counterparts. You can expect to find a wide variety of themes, bonus events, and payout structures. Some of the most exciting innovations include cluster payoffs that replace traditional paylines, mystery chases through Crime Zones in NetEnt’s Cash Noire, and outer-space adventures in ReelPlay’s Cosmic Convoy.
