Video Guide How to Play Slots Online

We have created a video guide to show you the very basics of how to play slots online.

A Brief History of the Slot Machine

The first slot machine called the ‘Liberty Bell’ was invented at the turn of the 20th century by Charles Fey, a young mechanic from San Francisco, California. Up until then, the original machine was a 5-reel game based on poker that didn’t pay out any real money winnings.

Charles Fey’s invention had three reels and an arm on the side to start the reels spinning. Rather than the complicated format of poker, a player now simply needed three matching symbols to win: hearts, horseshoes, spades, diamonds, or liberty bells, which also gave the machine its name. Winnings were paid out in cash, and now it was much easier to hit a winning combination.

The slot machine has undergone a massive evolutionary change since it was first invented in the 19th century. The dawn of a new digital age gradually allowed developers to take the traditional ver-sion of the one-armed bandit and expand on it in a multitude of ways. With technology driving the online gaming industry, many unique games and innovative features were introduced to satisfy every type of player. In fact, there are so many online slots available these days that the choice can be overwhelming.

Online Slots Gameplay

These days, slot games feature some of the most incredible graphics and interesting game elements that catch your eye. But for a slot to really shine, the vibrant and colourful visuals have to be backed by dynamic gameplay. We particularly love slot games that take you on a journey through multiple levels with plenty of opportunities to unlock bonus features, such as free spins and mini-games.

While we’ve been investigating all the new online slots 2021 has to offer, we’ve seen plenty of slots that offer this popular type of extended gameplay — and we’ll be sure to point you in their direction.

Reels and Paylines

The traditional set-up for one-line slot games is 3 reels, 3 rows and 9 paylines. For a win, you need to get a line, either vertical or horizontal, of 3 matching symbols. The payout will depend on which symbols you land, as some have a higher value than others. For more information on fast payout casinos check out our guide.

Multi-line slots can come in all shapes and sizes. They usually have five columns and three to five rows. Multi-line slots are distinguished from one-line slots by larger numbers of lines — five, ten, twenty, or more. Winning combinations can be achieved vertically, horizontally, or diagonally.

More Paylines and more Features

With more paylines and more features, multi-line slots have taken over their less complex predecessors in terms of allure and excitement. With multi-line slots, winning is not a matter of lining up a set of cherries. Instead, there is an infinite array of ways to win, which usually offers a lot more entertainment.

Not to mention that players’ win potential is usually a lot greater since there are more paying symbols, which means the increase of winning combinations. So it comes as no surprise that at MrCasinova.com, we’ve seen a growing number of slots shrug off this set-up in favour of more reels and rows, leading to a much greater amount of paylines.
