These spin and win attractions are the most popular online casino games, since there aren't any complicated strategies to employ with slots games.

Today, we're going to pull back the curtain on online slots. While they all present in the same way – digitally on your screen – there are tremendous differences between them. Our fascinating reveal all begins with a brief discussion of slot machine functionality. This forms the bedrock of our discussion, since your online slot games selection depends wholly on how these wondrous machines work for you. Without further ado, let's get started.

How do Online Slots Work?

While mechanical slots rely on a cumbersome physical apparatus with steel parts like cogs, pins, wheels, levers, springs, and the like, online slots are computer-generated wunderkinds. Remarkable audio-visual elements are instantly generated on your screen, on PC, Mac, and mobile. Slots outcomes are determined RNGs. These random number generators are complex algorithmic programs which ensure that the outcome of every spin is random.

Slot machines feature reels, symbols, in-game features, functions, and rounds of play. They're all different, and yet they are presented as a unique category of online casino games. The prestigious honour of the best online slot game is not one to be taken lightly. Players routinely seek out the best online slots according to their preferences, like risk/reward preference, minimum/maximum bets, features and functions, jackpot potential, volatility and variance, et al.

The simplest explanation of how online slots work from a player's perspective is as follows:

  • Select your preferred slot machine game
  • Choose your bet size according to the coin value per line
  • If there are variable paylines in play, select your preference
  • Click the spin button

In a strict sense, classic slots games run on 1 - 3 paylines, with just 3 reels in play. It is worth pointing out that modern-day slot machine manufacturers, and online software providers create video slots with a vintage-style look and feel. These can also be considered classic slots games.

The Online Jackpot Slots Games

Jackpot games are arguably the most-played online casino games in the slots series. There are several different types of jackpot games, notably Daily Jackpots, where players compete with one another on a jackpot network for the Daily Jackpot shared by a variety of affiliated slot machine games. Like Progressive Jackpots which also take a percentage of every real-money wager and add it to the Progressive Jackpot prize pool, Daily Jackpots also do that, but they pay out every single day before the countdown timer hits zero.
