All math problems, scoring logic, and screen-by-screen mock-ups are ready; the remaining step is transforming them into a smooth Android game and pushing it live on Google Play. The build can be in Java, Kotlin, Flutter, unity—whichever stack lets gameplay feel most responsive while keeping future updates straightforward. The visuals only need to replicate my mock-ups faithfully; you are free to optimise under the hood for performance and reduced APK size. Core functionality to implement: • Google Play Games Services leaderboard so students can compare scores. • Secure, device-synced progress tracking that survives reinstalls. • Simple multiplayer (turn-based or real-time) for puzzle races. Additional needs: • Automatic language switch based on the player’s device locale, with an option to lock a country language from settings. • Clean analytics hooks so I can review level-by-level accuracy. • A signed release build uploaded and approved in my Google Play Console, including icon, screenshots, and privacy policy I will supply. Deliverables 1. Complete, well-commented source code and build files. 2. Production APK/AAB published to Google Play and reachable via public link. 3. One-page hand-off guide covering how to update questions or add new languages. I already provide every graphic asset, the full question bank, and the game flow in Figma. The project is finished when the listing is live and installs run without crashes on current Android versions.

Hello, I understand you want a smooth, engaging K-12 math game for Android using your prepared questions, mock-ups, and scoring logic. I’ll pick the best tech (like Kotlin or Flutter) to make gameplay responsive and easy to update later. The game will include leaderboard integration for Google Play Games, secure progress sync that helps if the app’s reinstalled, and multiplayer race mode. Language will switch automatically by device locale but can be locked manually. I’ll also add analytics so you can track accuracy per level. Once done, I’ll upload the signed release to your Google Play Console, complete with your assets and privacy details. You’ll get clean, well-commented code, the published app, plus a simple guide to manage future updates and languages. I’ll make sure it runs smoothly and crash-free on current Android devices. What’s your preferred tech stack among Kotlin, Flutter, or Unity for this project? Do you have a specific method or service in mind for syncing progress securely across devices? Could you clarify how complex the multiplayer races should be: turn-based or real-time? Is there any specific analytics platform or tool you want integrated for tracking accuracy? Do you already have setups like a Google Play Console developer account and all required assets ready for submission? What is your preferred tech stack among Kotlin, Flutter, or Unity for the game development? Looking forward to helping launch your math game, Best regards,

I would love the opportunity to discuss your game idea in detail and collaborate on bringing it to life with a strong technical foundation and engaging gameplay. Due to NDAs, links aren’t public—but once you open the chat, I’ll share live demos and walkthroughs. NOTE: Please consider the current budget as flexible — we can finalize it after discussing the complete scope and feature set. Thanks & Regards, Kajal

Hi, I will build your K-12 math game in Kotlin — implementing the leaderboard via Google Play Games Services, device-synced progress tracking through Firebase, and the multiplayer puzzle race mode — then publish a signed AAB to your Google Play Console. For progress sync that survives reinstalls, I will tie saved data to the student's Google Play Games account rather than relying solely on local storage. This way, switching devices or reinstalling restores all progress automatically without needing a separate login system — keeping friction low for younger users. Questions: 1) For multiplayer puzzle races, do you prefer turn-based or real-time — and how many concurrent players per session? 2) How many locale languages need to be supported at launch? Looking forward to potentially working together. Thanks, Kamran

Hi I can turn your finished game logic, question bank, and mock-ups into a polished Android release that feels fast in play and is structured for easy updates later. The main technical challenge here is not drawing the screens, but implementing leaderboard, synced progress, multiplayer, locale handling, and Play Console release correctly without creating fragile game state or bloating the app. For this project, I’d lean toward Flutter for fast UI parity from Figma and simpler long-term content updates, or Unity only if the multiplayer/game loop becomes more complex than it appears from the brief. I can build the full gameplay flow, Google Play Games Services leaderboard, secure cloud/device-synced progress, multiplayer mode, locale-based language switching with manual override, and analytics hooks for level-by-level accuracy. I’ll also prepare the signed release build, configure the Play Console assets you provide, and support the submission flow through public launch. My experience covers Android app/game delivery, Google Play integration, release signing, analytics setup, and building maintainable mobile products from supplied assets and logic. And I can help you so on by keeping the codebase clean and well-commented, with a hand-off guide showing exactly how to add questions or new languages later. I’m comfortable taking this from Figma/assets to a live Google Play listing with stable installs on current Android devices. Thanks, Hercules

Hi, I understand you already have the full game design, question bank, scoring logic, and mockups ready, so the focus is building a smooth, responsive Android math game and publishing it successfully to Google Play. The app needs to feel fast and engaging while supporting leaderboard competition, multiplayer interaction, progress persistence, and localization. My approach would be to develop the app using a performance focused stack such as Flutter or Unity depending on gameplay responsiveness needs. I would implement the core gameplay loop exactly as defined, integrate Google Play Games Services for leaderboards, and build secure progress syncing using local storage with cloud backup support. Multiplayer would be designed as lightweight turn based or real time sessions depending on your preference. I will also implement dynamic language handling based on device locale with override settings and integrate analytics for level performance tracking. Before delivery, I will test gameplay across multiple Android devices, validate leaderboard and multiplayer flows, ensure progress persistence after reinstall, and confirm localization and analytics accuracy. I will also complete store submission, verify installation stability, and provide a clear handoff guide. Best, Justin
