Web Game Developer — Casual “Pop & Grow” Game

We’re looking for an experienced developer to build Pop & Grow, a simple browser game for desktop and mobile. Players tap colorful bubbles, earn points, and watch a small garden grow. We have a game design document and screen concepts ready. We need someone who can turn them into a polished, responsive game with a secure backend and withdrawal system. About the game The gameplay should be easy to understand immediately: - Tap a bubble to pop it and grow a flower. - Each bubble normally awards 5 points. - Each garden contains five bubbles. - Complete a garden and move to the next one. - No difficult puzzles, precise timing, or failure penalties. The visual style should feel bright, relaxing, and satisfying, with smooth animations and optional sound. Core requirements - Responsive gameplay for mobile and desktop browsers. - Permanent user accounts with secure login and recovery. - Access-code activation with a four-hour window controlled by the server. - Garden progression, saved progress, and reliable reconnection. - Points wallet, transaction history, and withdrawal requests. - Administrative dashboard for users, access codes, rewards, withdrawals, and support. - Integration with approved card and crypto payout providers. Reward rules - 100 points = CNY ¥1. - Intended earning range: CNY ¥20–¥25, with a hard cumulative user cap of 2,500 points / CNY ¥25 before disclosed withdrawal fees. - A withdrawal or new access code must not reset the user’s earning cap. - The backend must prevent duplicate rewards, repeated withdrawals, and concurrent requests exceeding the cap. - If the platform later hosts multiple games, the account-level cap must work across them. Access codes will eventually be purchased and delivered by email. Checkout and email delivery are outside the initial development scope, but the game should support their future integration. Skills we’re looking for - Experience building and launching browser games or interactive web applications. - Strong JavaScript/TypeScript and responsive frontend development skills. - Experience with React and browser animation; Phaser or a similar framework is welcome where appropriate. - Backend API, authentication, and relational database experience. - Understanding of secure financial records, payment callbacks, request deduplication, and reconciliation. - Ability to produce smooth, accessible gameplay on ordinary mobile devices. Please propose a practical technology stack. We value clear reasoning and maintainable code. Expected deliverables - Playable game and responsive website. - Backend, database, and admin dashboard. - Tested reward limits and payout workflows. - Source code in our repository. - Deployment setup and technical documentation. - Handover and an agreed period of post-launch bug fixes. Development should begin with a playable prototype using simulated points, followed by the full game and backend. Live payouts will depend on selected providers and their approval. To apply, please send 1. Links to relevant games or websites you personally developed, explaining your role. 2. Your proposed stack and development approach. 3. An estimated timeline, milestone breakdown, and price. 4. Your experience with payment or withdrawal integrations. 5. Whether you can create the game’s visual assets or need an artist. 6. Your availability and post-launch support terms. Project type: Remote freelance/contract Budget: Please quote based on the design document and scope.
