How to Publish and Deploy Your Game Online (PC, Mobile & Web Platforms)

So, you’ve built your game. You’ve tested it. Maybe you’ve even deployed a multiplayer server. Now comes one of the most exciting parts: getting your game into players’ hands

I still remember the thrill of publishing my first game online. Seeing someone download and play something I made from scratch is a feeling you don’t forget.

Publishing isn’t just about uploading a file. You have to prepare your game properly, consider platforms, optimize builds, and make the process smooth for players. In this guide, we’ll walk through publishing for PC, mobile, and web, while keeping beginner developers in mind.

Step 1: Prepare Your Game for Deployment

Before you publish, make sure your game is ready:

  1. Final Build Testing – Test on multiple devices to catch crashes or performance issues.

  2. Polish Gameplay – Ensure menus, HUDs, and controls are responsive and intuitive.

  3. Optimize Assets – Reduce large textures, audio files, and unnecessary objects to improve performance.

  4. Include Dependencies – Make sure any libraries or runtime environments are included or documented.

Remember, a polished game keeps players coming back. Bugs on release can kill your launch momentum.

Step 2: Export Builds from Your Engine

Different engines provide options to export your game to multiple platforms:

Unity

  • PC: Windows, macOS, Linux

  • Mobile: Android (APK), iOS (IPA)

  • Web: WebGL

Steps:

  1. Go to File → Build Settings

  2. Select target platform

  3. Configure resolution, graphics, and quality

  4. Click Build

Unreal Engine

  • Uses Package Project for Windows, Mac, Android, iOS

  • Web builds are possible with HTML5 export (experimental in recent versions)

Godot

  • Export templates are needed for each platform

  • Supports Windows, macOS, Linux, Android, Web (HTML5)

Tip: Test each build on its native platform before distribution. Web builds may need server hosting. Mobile builds need device provisioning (especially iOS).

Step 3: Choose a Distribution Platform

Where your game is published depends on your target audience.

PC

  • Steam: Largest PC audience, revenue share applies, requires review and submission

  • itch.io: Indie-friendly, flexible pricing, direct uploads

  • Direct Download: Host files on your website or a server

Mobile

  • Google Play Store: Android, requires developer account, APK submission, review

  • Apple App Store: iOS, requires developer account, strict review process, provisioning profiles

Web

  • Web Hosting: Upload HTML5/WebGL build to your server or platform

  • itch.io Web Uploads: Great for small indie games

  • Game Jolt / Kongregate: Indie-friendly platforms

Each platform has requirements and restrictions, so read their guidelines carefully.

Step 4: Connect Your Game to Online Servers

If your game is multiplayer:

  1. Make sure the client build points to your live server IP or domain

  2. Test multiple clients connecting from different networks

  3. Handle connection errors gracefully (e.g., server down, player timeout)

This ensures players can start playing immediately without frustration.

Step 5: Optimize for Each Platform

Different platforms have different performance constraints:

  • PC: Can handle higher graphics, but optimize for multiple GPU/CPU types

  • Mobile: Limited memory and battery, optimize textures and logic

  • Web: Browser-based, optimize for low bandwidth and smaller asset sizes

Optimization reduces crashes, lag, and negative reviews.

Step 6: Security and Anti-Cheating Measures

Even small games need security:

  • Validate all critical gameplay actions on the server

  • Encrypt sensitive data if storing accounts or transactions

  • Rate-limit actions to prevent abuse

  • For mobile, obfuscate code and protect assets where possible

Security ensures players trust your game.

Step 7: Marketing and Launch Preparation

Publishing is not enough. You need visibility:

  • Create screenshots, trailers, and gameplay videos

  • Write an engaging description with keywords

  • Share on social media and community forums

  • Offer demos or beta tests to generate feedback

Even a simple launch plan can make a huge difference in player uptake.

Step 8: Post-Launch Updates and Maintenance

Publishing is just the beginning:

  • Monitor server performance if multiplayer

  • Fix bugs and push updates regularly

  • Respond to player feedback

  • Add new content to retain interest

Active post-launch support builds trust and community around your game.

Summary: Platform-Specific Checklist

Platform Build Format Distribution Special Notes
PC EXE / DMG / AppImage Steam, itch.io, Direct Test on multiple OS versions
Mobile Android APK Google Play Test device compatibility
Mobile iOS IPA App Store Provisioning profile required
Web HTML5 / WebGL Your server, itch.io Optimize for browsers and bandwidth

Final Thoughts

Publishing and deploying your game online is the moment all your hard work pays off. It’s exciting, stressful, and rewarding all at once.

A polished, optimized, and properly deployed game ensures:

  • Players can download or access it easily

  • Multiplayer features work reliably

  • Cross-platform reach maximizes audience

  • You maintain control over updates and scaling

If you follow these steps carefully, even a beginner can go from a local prototype to a live, playable game across multiple platforms.

Remember:

The first player to connect, play, and enjoy your game is a milestone you’ll never forget.
