How do you get it running?

Difficulty · hard Time to first run · 1h+

Requires installing the Realm Mobile Platform, creating admin and game-user accounts, generating credential files, configuring a shell script with IP and file paths, plus CocoaPods for iOS and Android Studio for Android.

The explanation does not mention a license, so usage terms are unknown.

So what is it?

RealmPop is a simple, real-time two-player mobile game where you race against an opponent to clear a board of numbered bubbles by tapping them in descending order. Tap the highest available number each time to clear it, and whoever finishes first or outlasts their opponent wins. If you tap the wrong number, you lose the round instantly. If you take more than 60 seconds, you also lose. The game exists primarily as a demo for the Realm Mobile Platform, a service for building real-time apps that sync data between devices. Behind the scenes, a small server-side component handles custom game logic, and there is a web-based high scores board that updates as games are played and won. The project includes full client apps for both iOS and Android, plus a Node.js server piece that ties everything together. This would appeal to someone learning how to build real-time multi-player mobile games or anyone evaluating Realm's sync capabilities. A typical use case: you are a founder or PM curious about how a live two-player game feels when powered by a real-time database backend. You can run the whole thing locally on a Mac, deploy the iOS or Android app to your phone, and play against someone else on your local network while watching scores populate on a web leaderboard. Setting it up is fairly involved. You need to install Realm's server platform, create admin and game-user accounts, generate credential files, and configure a shell script with the right file paths and your machine's IP address. The iOS app requires CocoaPods dependencies, and the Android app is built through Android Studio. The README does not go into detail about gameplay strategy beyond the basic rules, it is really a developer walkthrough for wiring up the full stack rather than a player-facing guide.

Copy-paste prompts

Prompt 1
Set up the RealmPop demo locally: walk me through installing the Realm Mobile Platform, creating admin and game-user accounts, generating credential files, and configuring the shell script with the correct file paths and my machine's IP address.
Prompt 2
I have the Realm Mobile Platform running, help me install the CocoaPods dependencies for the iOS app and build the Android app in Android Studio so I can deploy both to physical devices on my local network.
Prompt 3
Explain how the RealmPop Node.js server component ties the iOS client, Android client, and web leaderboard together, and how the real-time data sync works when two players are competing.
Prompt 4
I want to modify the RealmPop game rules so that tapping the wrong number deducts points instead of ending the round, show me where the custom game logic lives on the server side and how to update it.
Prompt 5
Help me troubleshoot why the web high-scores board is not updating when games are played on my local network setup.
