Video Slots for Online Casino Owners: Best Choice in 2019

Video Slots for Online Casino Owners: Best Choice in 2019

Updated 23/09/2021

Slots can be called the main tool that brings income to the owner of the gambling website. It is on the machines that the largest number of bets is made. They are preferred by all gamers, regardless of age, country of residence and income level.

Let us find out what video slots for business exist, how they differ and what products are better to use for an online casino so that the operator earns well, and visitors were satisfied with the game.

Video slots for online casino owners

Understanding the classification and differences between slots, you will sort out what gamblers are waiting for, what they need for an exciting game, and how exactly the monetization of machines takes place. First, let us find out what a video slot is.

What Are Modern Slot Machines?

A few decades ago, the slot machine was a box with ingenious mechanical bowels, and the reels were started by pressing the handle. Those famous “one-armed bandits” were the prototypes of modern 3D slots, which amaze with bright graphics and astonishing animation.

Vintage mechanical machines have laid the foundation, so today any video slot in the casino is based on the same idea as to its predecessors. The only difference is that the result of the rotation of the reels is determined by the software algorithm, and the symbols on the screen can even interact with the player.

Thus, an automated device is a program that visually consists of two components:

  1. The playing field traditionally consists of 9 (3x3), 15 (5x3) or 20 cells (5x4). This is a window in which only part of the vertical reels with symbols is visible. Usually, the gamer can see three or four characters.
  2. Control panel is several buttons located on the side or under the playing field. They allow adjusting the desired format of the game, choose the bet amount and start the rotation of the reels in automatic mode.

There is also a section for gamblers with additional information: rules, table of coefficients, description of functions of special symbols.

How to Make Money on Slots?

Gambling is attractive because you never know, whose account the money will be transferred to after another spin. Both the operator and the gambler can win, even if it is a beginner.

Video slots: how to make money in a gambling business

The developers of slots face a serious task: they need to make the slot profitable for the owners of the gaming business and at the same time interesting for gamblers. To understand the solution, we will consider the concept of RTP — the percentage of return of funds invested by the player.

RTP shows how much money a gambler can return on each particular video slot over the long run. In recent years, the top providers produced machines with RTP at the level of 95-98%. Let us understand what it means.

If the gambler has replenished a deposit of $100 and started the game, then in the future he will return from $95 to $98 in his pocket. The remaining difference is the casino’s earnings. No matter how the game takes place on specific days, as a result, the Internet business still remains in the black and consistently earns.

What Is Volatility?

Another important parameter that characterizes the slots is volatility. In simple terms, this value shows how often players receive prizes.

Volatility can be of several types:

Types of volatility


Suitable for


Prizes fall out often, but their amounts are insignificant. For example, at a bet of 50 cents gambler can receive only 10 cents per spin. There is a win, but it does not cover the bet

Players who want to often receive small prizes


Winning combinations are formed on the field very rarely, but the payouts are large and can cover all previous bets

Gamblers who are willing to idle spin the reel at least twenty times, but then hit a good jackpot


Balanced ratio between the number of spins and winnings on them

Perfect for beginners who are just getting acquainted with online gambling

The operator needs to have slots with different volatility indicators on the website to satisfy the audience’s preferences.

Principles of Winnings Formation

Slot machines, as before, give the player a payout in the event that on the field after the reels stop there will be a winning combination — a chain of identical symbols (from left to right), in which each link must belong to the next reel. In addition, the combination may include special symbols (wilds or setters), if the developer has provided them with the function of replacing other icons.

Usually, the machine pays out the winning if the length of the chain is 3 or more symbols. The longer the combination is, the bigger the prize will be. For slots with three reels, 5 identical icons give the biggest profit. And if the chain consists of certain rare symbols, the player can hit the jackpot.

What Slot Machines Should Be Accorded Priority?

Of course, on the website should be installed only reliable video slots from trusted providers.

We have compiled a small review of the brands that produce the best gambling games:
