Slot game development can seem like a daunting task. What’s more, it requires the developer to have a keen eye for detail. Since the advancement of technology has accelerated game development, video games have come a long way. Slot games are no different, with the help of the latest development methods, casino games are starting to look like real-life slot machines. With this idea in mind, it is crucial to understand the importance of game testing for slot game development because a slot game needs to meet the highest standards to compete with the competition. 

Slot Game Development Process

During the stage of slot game development, the features, game idea, documentation, and requirement analysis is done. The game development phase can include the feature specifications, design documentation, development of game architecture, frame overlay, and animations. There are some things to also keep in mind when entering the testing phase. For instance, player’s action attributes, rules, game flow logic, scoring, player’s statistics, objects, etc. There is also a need to test special effects, titles screens, triggers for special events, and actions of buttons. The point of this article is to look at some other types of post slot game development, and understand their importance. 

Functionality Testing

During slot game development, there is a need also to test the functionality of the game to ensure quality assurance. There might be a need to look for any generic problems that can be faced during gameplay. You can come across bugs within the user interface and slot machine graphics; there might be some problems with the game mechanics, stability issues, and even the game asset integrity can run into trouble. Thorough testing of the user interface is critical because it can define the friendliness of the game towards the players. 

Slot game developers may also need to check things like screen resolutions that might change depending on the device used. Simple things like font size can matter during the development process. Sequences, animation, and design, audio, instructions are all aspects that may be overlooked during development. Backgrounds and colors can glitch on other devices, and this needs to be checked on multiple devices post-launch to ensure quality gameplay regardless of the device. Since some slot games will be run on mobile devices, there also comes a need to check game accuracy regarding screen resolution, mobile responsiveness, and audio quality. 

Compatibility testing

Since online casino game development is being developed with convenience in mind, they need to be able to run on different devices. Compatibility testing will ensure that the slot game that is produced can run across any supported hardware. Developers usually uninstall and install the games numerous times to ensure a smooth installation. The slot game needs to be checked on desktops, mobile phones, laptops, and any device supported. Besides this, they need to be checked regarding different configurations, both software, and hardware-wise. 

Performance check

During this phase, the general performance of the slot game is tested. If required, performance tuning is done to optimize the game speed. Any player would not enjoy a slot game that lags, and freezes continuously. There are some important parameters to check during the performance phase. Since most slot games are played online, checking response times on clients and servers are of the utmost importance. Since there is money involved in some games, transaction completion times are also critical. Any issues a player might run into during this period can have massive consequences. It’s also necessary to check the data download speeds of the slot game, and the time a game takes to connect to servers. 

During slot game development, there is a particular need to look at the battery consumption of games. This aspect is closely tied to the graphics performance of a slot game. Battery consumption may not be important when it comes to desktop devices, but since most slot games can run on mobile devices, the need for battery optimization can play an important role. The usage of the battery should be optimum when playing for extended periods. The responsiveness of the game should also be controlled when playing across many devices under heavy loads. 

A player will become displeased if the game consumes almost all of the processor and RAMs. So during slot game development, developers use performance counters to check the consumption of CPU and RAMs. If the usage is heavy, it may lead to the heating of the device, and create lag during gameplay. 

Testing for global markets

During slot game development, developers mostly aim to reach global markets. Launching a slot game only in the English language would mean fewer players, compared to a multilingual game. During this testing phase, content, texts, and game titles all need to be tested on devices that support multiple languages. Most of the time, these tests can be done quickly. Developers usually use test automation and cloud-based tool accessing to help speed up the process. 

Slot games, for example, will need MENA and double-byte character support to be compatible with the Middle East and East Asian languages, respectively. For middle eastern regions, the game should support right to left text and two directionally display support. When it comes to East Asia, however, there will be a need for pseudo-localization testing. Regardless of the regions, developers need to optimize local time, and date compatibility, address formatting, currency, and other types of local requirements that need to be checked. 

Soak tests

Soak test is an essential part of post slot game development testing. This phase is also crucial for any type of game development regardless of genre. The examination requires leaving the game running for extended periods in different modes. Developers usually leave the game on title screens, idle modes to run the tests. With the help of Soaking, the developer can identify any rounding errors or memory leakages. 

After running the game, the tester usually leaves the game open for around 24 hours. During this time, the developer can detect any issues regarding the game engine, or discover a crash that may occur because of a memory leak. 

Recovery test

Any slot game can be prone to crashing. Recovery testing checks to see how well the game can recover from the crash. This crash can be a result of failures that happen outside of the game, like a hardware failure. The key to check how well the software handles sudden interruptions. Developers usually force the slot game to fail on purpose, depending on the environment and conditions, the developer will observe the recovery process. 

This process is done by suddenly shutting down a device during typical gaming sessions. Since a slot game runs on a game server and stores data, it is vital to check for any data loss that may occur as a result. A player should be able to have access to his or her data after a sudden hardware or software crash. Not being able to do so, can result in the drop of popularity for the game. 


Various methods of post-development checks and balances for slot game development is very crucial. Slot games should be able to run fluently on multiple devices regardless of hardware selection. If a game is not polished and does not run smoothly, a player will simply move on to the next slot game. Post publishing tests should not be overlooked in this regard. There are so many games to choose from. Creating a buggy game will only damage your image and create issues for you. Each testing phase checks scenarios in its regard, making it essential not to miss any!
