How We Updated & Upgraded A Game That No Longer Worked Properly on Android


Our client, an individual in the gaming industry, came to us to improve his Android game, where players raced an RC car up and down hills and around obstacles. He wanted to upgrade the application so it would run smoothly on the latest version of Android.

First, he needed to upgrade existing plugins. Second, he needed to implement a new multiplayer feature.

Our end goal was to make the updates, upgrade the UI, and get the game up and running on the Android platform.


The application was simply old and couldn’t keep up with the latest features and capabilities of the Android environment. Android updates caused behavioral changes in the app, and as a result, game plugins had become outdated. The game wasn’t running smoothly on the latest Android devices and so the client was missing out on new players for his game.

This was not something new for us. In fact, we’ve have extensive experience developing and updating games for iOS and Android, so we’d already experienced similar situations and knew exactly how to proceed.

The single biggest challenge was to update the existing plugins in Unity 6.0, although they were developed in Unity 4.0.


It took 2-3 weeks to design the solution and 8-10 weeks to implement it.

Before we were able to view the code, based on what we knew about previous android updates, we made an educated guess about how much development and fixing the code base would require. We would need to upgrade certain plugins and find updated plugins to perform a similar function and provide similar UI.

But when we were able to view the actual code we realized that it would need much more work than we previously thought.

The first step was to do high-level research.

We listed the plugins which needed upgrades and identified which upgrades were available. When we shared the list with the client, he was able to make some of the changes himself… but the remaining plugins were to be upgraded by us one by one (along with solving issues in the code).

We had a project manager and a team lead who was experienced Unity game development involved in this stage. With the guidance of the team lead, the developer worked on the code and fixed or upgraded all the necessary plugins.

After everything was working correctly, we shared the build with the client. He played and tested the game and shared feedback. We made changes accordingly.

Once the client accepted the final changes, we closed phase 1 of development.

Phase 2 took much less planning and preparation. We simply implemented the multiplayer feature. In the new upgraded application, everything went smoothly.

  • UI/UX
  • Front-end Dev
  • Back-end Dev
  • SEO
  • Unity 3D Game Engine
  • C#
  • 2D & 3D Graphics

The final deliverable the client received was the latest version of the application, with the UI upgraded, all plugins updated and fixed, and a multiplayer feature. The client said he was satisfied with how it turned out.

The result? A better game with more user engagement.

We expect this to lead to better reviews and more downloads from the Android store.

Great experience working with the Capital Numbers team. They were extremely diligent, accessible and utmost professional in their work. They were worth every euro. We are happy with the results they showed us and also the solutions they come up with to satisfy our needs. I definitely recommend working with them. It is useful to have someone on your side who does have (although limited) knowledge of IT and web hosting.

We have found Capital Numbers extremely easy to work with as development partners. They have been great at spending the time on the front-end of projects to understand the full scope which is helpful during development to guide decision-making and potential trade-offs to deliver on time and within budget. They're effective at integrating technical solutions with creative work and we have had a great experience with their project management.
