Building My 29 Card Game App Using AI + Kotlin (Jetpack Compose)

 

🎮 Building My 29 Card Game App Using AI +  Kotlin (Jetpack Compose)

🚀 Introduction

The 29 card game is one of the most loved trick-taking card games in India. Growing up, I played this game countless times with friends and family. Recently, I decided to bring this classic experience to mobile — and not just in a traditional way, but by using AI-powered development.

In this blog, I’ll share how I built my offline Android game using Gemini Agentic AI, Kotlin, and Jetpack Compose, and successfully published it on the Google Play Store.

📱 Try the Game

You can download and play the game here:
👉 https://play.google.com/store/apps/details?id=com.developergame.cardgame29

This is a fully offline game, so you can enjoy it anytime without internet access.

💡 Why I Built This Game

I wanted to:

  • Digitize a traditional Indian card game

  • Create a lightweight offline experience

  • Experiment with AI-assisted coding (Gemini)

  • Improve my Android development skills using modern tools

🤖 Using Gemini Agentic AI

One of the most exciting parts of this project was using Gemini AI to speed up development.

Here’s how it helped me:

  • Generated game logic ideas

  • Assisted in writing Kotlin functions

  • Helped debug issues faster

  • Suggested UI improvements

Instead of replacing development, AI acted like a smart coding partner.

🛠️ Tech Stack

I used modern Android development tools:

  • Language: Kotlin

  • UI: Jetpack Compose

  • IDE: Android Studio

  • Architecture: Clean & modular approach

  • AI Support: Gemini Agentic AI

Jetpack Compose made it easier to design a clean and responsive UI without XML.

🎯 Key Features of the App

  • 🃏 Classic 29 card gameplay

  • 🤖 Smart AI opponents

  • 📶 Fully offline (no internet required)

  • 🎨 Clean and modern UI

  • ⚡ Lightweight and fast

🎮 Challenges Faced

Building a card game is not as simple as it looks. Some challenges I faced:

  • Implementing bidding logic correctly

  • Managing AI player decisions

  • Handling game state and turns

  • Designing a smooth and intuitive UI

With the help of AI and continuous testing, I was able to overcome these challenges.

📈 Publishing on Play Store

After development, I:

  • Generated a signed APK / App Bundle

  • Created Play Store assets (icon, screenshots, description)

  • Uploaded and tested the app

Seeing the game live on the Play Store was a really rewarding moment.

🔮 What’s Next

I plan to improve the game by adding:

  • Multiplayer mode (online)

  • More animations and sound effects

  • Leaderboards and achievements

🙌 Final Thoughts

This project shows how traditional games + modern AI tools can create something exciting.

If you're a developer, I highly recommend experimenting with AI tools like Gemini — they can significantly boost your productivity.

And if you enjoy card games, give my app a try and let me know your feedback!
