Themes and design 

The theme and design of a slot machine play a major role in its overall appeal.

Quality of graphics and animation 

Your enjoyment of a slot machine can be thoroughly dependent on the quality of its graphics and animations. 

Whilst these are not the only criteria that you should take into consideration, they play a major role in the impact that the game can have on you. 

When sifting through a provider’s game library, it will not be unlikely for you to find some hidden gems that appeal to your specific gaming preferences. 

Modern games, in particular, often include innovative game mechanics, top-notch graphics, and 3D animations. In addition to this, detailed character designs and dynamic reel effects are rarely lacking in these types of gaming options. 

Ultimately, the overall quality of a slot machine’s graphics and animation provides a significantly more immersive experience for the player. 

RTP and volatility 

Both the RTP and the volatility of a slot machine play a significant role in helping you determine its potential profitability. 

RTP (Return to Player): The RTP percentage of an online casino game refers to the potential rate of return at which players can expect to generate winnings over a very long period of time. Remember that this value is purely theoretical.

• A useful tip to keep in mind: A good software provider will typically offer titles with an RTP percentage above 95%. This is because this value is a great indicator of a fair payout rate. 

Volatility: A game’s volatility affects the frequency and the size of your potential winnings. In other words, it is a measure of risk associated with how often and how much a slot will pay out. 

• A low volatility slot will pay out very often, but each win will be small in size. 

• A medium volatility slot will have moderately frequent wins, with medium sized wins. Here, a balance is struck between frequent small wins and infrequent large wins. 

• A high volatility slot will not pay out often, but each win will be large in size. 

Provider reputation 

The reputation of a software provider is wildly influential on the player’s decision to play its selection of games: A key factor of players’ trust and engagement is uniquely tied to this reputation. 

Software providers that consistently manage to deliver a unique and thrilling gaming experience to their players, including high-quality, fair, and entertaining titles, are easily classified as reputable and trustworthy game suppliers. 

A reflection of their credibility also stems from their long-standing partnerships with reputable online casinos in the industry. 

These special breeds of software providers are also those who prioritize quality over quantity, having carved out a niche in the market belonging wholly to them.  

Regulation and licensing 

Essential criteria for determining the legitimacy of a game supplier are their possession of certifications and licenses in multiple jurisdictions. 

Software providers that have been awarded such licenses can ensure that the games they consistently release will be both fair and safe for you to play. 

Some well-known gaming licenses include the Malta Gaming Authority (MGA), the UK Gambling Commission (UKGC), and the Curaçao eGaming License. 

In order to obtain such licenses, entities must adhere to some very strict standards set by the gaming authorities that harness the power to award them. For this reason, you can be at ease in the knowledge that fair gameplay and player safety is guaranteed.
