Choice of games is an important feature of online casinos. Players want good entertainment value and a wide selection of games to try. A casino should have hundreds of exciting games. This should include colorful video slots, intense table games, and high-stakes jackpots. Ideally, an immersive live dealer experience should also be available.

This is influenced by software developers that produce online casino games. Developers are an integral part of the game selection process. Iconic companies like Microgaming, Evolution Gaming, and NetEnt service online casinos and provide them with the games we know and enjoy.

What do Software Developers do?

Online casinos do not create their own games. This would involve too much work and expense. As a result, online casino operators use third-party software developers to provide games. A casino may work with a single developer, or they may reach out to a handful of different providers to create a larger game catalog.

Software developers create casino games and sometimes downloadable casino software. They use different technologies like Flash and HTML5. Flash used to be the prominent programming language; however, it is now obsolete. HTML5 is now considered the industry standard due to its flexibility and power.

The game production cycle typically involves:

  • Market research to find target audience etc.
  • Drafting initial ideas and concepts.
  • Translating ideas into a workable game.
  • Internal gameplay testing.
  • External testing of RNG systems.
  • Calculation of RTP percentages.
  • Promotion of game to online casinos.

External testing and RTP percentages are important aspects of each casino game. Ideally, games should have their RNG (Random Number Generator) systems tested for fairness to ensure the outcome of games is random.

Also, calculating the RTP (Return To Player) percentage gives the game a classification. It shows how volatile it is, and if it falls in line with industry averages which are approximately 95%.

What makes a software developer good?

So how can you separate good software developers from the bad? The following are 6 key points that help make a software developer successful:

Their games are externally tested

Both internal and external testing is vital for software developers. Firstly, a developer should test their games internally for playability and fairness. However, games should also be externally tested by a recognized testing lab.

Companies like eCOGRA and iTech Labs test games for fairness. Specifically, they test the RNG (Random Number Generator) systems to ensure game outcomes are truly random. A reputable software developer will have its RNG systems certified by an external testing lab.

They have a favorable RTP percentage

The RTP percentage of a game is the value a player expects to receive back over time. For example, let’s say a game has an RTP of 97%. If a customer spent R5000, over time, they should expect to receive back R4850, or make a loss of R150.

A higher RTP percentage means a greater chance of getting your original stake back. Reputable software developers publish their RTP percentages. Also, they have consistent RTP percentages that reflect expected industry averages.

If you find a software developer that has consistently low RTP percentages of less than 80%, this is an indicator of their poor quality.

They utilize the latest technologies

The best software developers use modern game technologies. They strive to keep their games relevant and utilize the latest technologies to provides customers with a fun gaming experience.

For example, you would not expect to see a software developer using Flash for its games. Flash is a programming language that is now obsolete in favor of HTML5.

They provide a diverse selection of high-quality games

Prolific game developers like NetEnt and Microgaming have perfected their craft. They have a diverse offering of games spanning multiple themes and categories.

Just remember that quantity doesn’t always equal quality, however. The large game offering should contain a consistent range of fun titles that players can enjoy – not just re-skinned games with different themes or graphics.

Their games are easy to use with clear instructions

Ease of use and clarity is vital for online casino games. Customers don’t want to spend time testing a game or trying to figure out how it works.

The best software developers create simple games that can be played with minimal effort. The instructions are clear, and the game interface and controls are intuitive.

The games are adaptive for both desktop and mobile play

The best modern software developers create games suitable for multiple platforms. It is no longer viable to simply create games for desktop casinos.

Ideally, a software developer will create games that have multiple versions for desktop computers, web browsers, and smartphones.
