Use case:
Netmarble Corp.


Netmarble Corp. is one of the biggest mobile-gaming company of the world. We worked with Netmarble to test several of their globally renowned games. Buglance global testing community tested their games, revealing critical bugs in multi-level games. Additionally, we identified latencies and lags that occurred in the games due to compromised internet connectivities.

  • Company Origin: South Korea
  • Countries Tested: UAE, Saudi Arabia
  • OS Versions Tested: All
  • Devices Tested: All

Latency Testing

We performed various latency tests to help Netmarble identify lags within their system, and test real-time multiplayer games in networks with low or ultra-low latency requirements. Such latencies were critical in identifying issues in the games in order to improve the game play and player’s experience.

Example of discovered bugs:

On 4G networks during battle opponents figures disappear randomly and re-appear after a period of time.

CDN Performance Testing

We checked dependencies of content delivery on speed of internet and provider type.

Example of discovered bugs:

Users on DU 4G network can not download additional content in the game and start the game.

Longitudinal studies

In longitudinal studies testers performed long-format testing where they played the game and tested accuracy many levels into the game.


Our community discovered critical bugs at the highest levels of the games.

Real User and Exploratory Testing

Real User testing, as well as exploratory testing is impossible to achieve in automated testing, and slow to perform in in-house testing. Buglance gives access to 50k+ real users, who can test your app efficiently.

Efficient and Scalable Testing

With access to a large testing community on Buglance you can scale your testing quickly. Your developers can focus on building the product, while Buglance community is going to be testing the application in parallel.

Hardware Diversity

There are only so many devices you can test on in-house or virtual environments. On Buglance you can test your application on more than 10k devices, and select a specific brand or range of devices.

Longitudinal Studies

In multi-level games, bugs can appear several levels in. Testers on Buglance will make sure to test for several days after downloading your game.


Testing Types

Exploratory Testing

Apply one of the most essential testing types in your games, where the testers do not take a planned approach, but naturally progress through hames and reveal problem areas.

Latency Testing

Test your game for lags and low latency. Discover critical bugs which occur in the game due to lags in the network and improve the user experience.

Multiplayer Testing

Multiplayer games are complex and hard to coordinate in testing in-house. Multiple testers from our community can test and report bugs that can occur in your games when multiple players are online.

Longitudinal Studies

In longitudinal studies testers complete multiple levels of the game to ensure that there are no bugs in the game from the first to last levels.


360-degree bug reports

Our community carefully tests mobile and web apps and provide you with an extensive, all covering bug reports.

As a part of those reports, our platform provides you with steps to reproduce the bugs, device information (model, screen size, ram and cpu capacity and more), connectivity details (upload and download speed), as well as screenshots and screen videos of the bugs.

AI based and crowdsourced bug validation and verification

Buglance operates on an exclusive AI & Machine Learning methodologies we developed in-house. With its help, Buglance achieves perfection in validating the bugs and verifying them.

Our community of professional testers work hand-in-hand with our AI tools to ensure the quality of the reports, and give you bug reports that we can replicate on thousands of devices.

Integration with your favorite tools

Each company has its internal tools. Some track issues through JIRA, while other prefer Trello, Asana and other task management tools.

No matter which is your favorite tool, Buglance provides seamless integrations with hundreds of tools across the spectrum to make your bug-tracking and bug-fixing process as comfortable as possible.
