What Are Online Slot Games?

Online slot games are computerized versions of the classic fruit machines you’ll find at many casinos. They have many different features, including wild symbols and interactive bonus rounds. They can also be played for free or for real money.

Unlike land-based slot machines, online slots use a random number generator to determine the outcome of each spin. The RNG uses mathematical algorithms to generate a new series of random numbers every millisecond, and the outcomes are determined instantly.

There are many different types of online slots, from 3-reel slots to 5- and 7-reel games. Each has its own unique theme and special features, so you’ll be sure to find a game that suits your tastes.

The best place to play online slot games is at an online casino that offers the best sign-up bonuses. These bonuses typically include a match deposit bonus and free spins. They are a great way to try out a new online casino without risking your own money.

Payout Percentage

The return to player rate, or RTP, is a key factor when choosing an online slot game. The higher the RTP, the more likely you are to win over time. This number is usually posted on the game’s rules page, or as a list on the casino’s or developer’s website.


Depending on the casino, some online slots feature progressive jackpots that increase in value over time. These are a good bet if you want to win big. However, keep in mind that these jackpots are only available to players in specific jurisdictions.

Wild Symbols

Online slot games often feature wild symbols that substitute for all other symbols except scatters. These symbols can appear on any of the reels and will trigger a variety of different bonus features, from free spins to special rounds.

Scatter Symbols

A scatter symbol appears on most online slot games and is worth more than a standard symbol. These symbols can activate a bonus round, which can lead to even more prizes. They can also trigger free spins, which are a fun and rewarding addition to any slot game.

Online slot games are a great way to pass the time, and they offer lots of ways to win money. The most popular types of online slots are 3D, classic and video, and players can choose from a range of themes. There are also mobile versions of these games, which can be played on smartphones and tablets. Some are even available in demo mode, so you can test out a new game before you wager any cash.
