Android Word Puzzle Game Development

I want to launch a word-puzzle game exclusively for Android that can turn a profit on Google Play. The gameplay revolves around players arranging or guessing words, with a clear difficulty curve spread across multiple, well-balanced levels—the only mandatory feature at this stage.

Please build the game in an engine you are comfortable with (Unity, Android Studio with Kotlin/Java, or Flutter are all fine) and include lightweight AdMob integration so the title can start generating revenue from day one. If you see other monetisation tactics that suit a word game, feel free to propose them, but keep the first release lean and focused on rock-solid core mechanics.

Deliverables
• Release-ready APK
• Full source code and project files
• Documentation on how to add or tweak levels
• Simple guide on swapping ad IDs and preparing the final Play Store build

Acceptance criteria
• Smooth performance on current Android devices (API 24+)
• At least 30 progressively harder levels fully playable without crashes
• Ad impressions confirmed in a test build
• All assets and code completely royalty-free or properly licensed for commercial use

If you can meet these points and have experience shipping Android puzzle titles, let’s discuss timelines and your approach.
