Multiplayer Puzzle Mini-Games App

I want to build a mobile app inspired by PlaySolo that launches with a real-time puzzle game and grows into a hub of quick, casual mini-games. The core idea is to let two players go head-to-head live, track their wins, and showcase their progress through persistent player profiles and a public ranking ladder. Phase 1 focuses on recreating the PlaySolo-style puzzle experience: • A polished, intuitive puzzle mini-game that matches two players instantly and keeps the round latency-free. • Secure sign-up/login (email, Google, Apple) that stores avatar, nickname, and basic stats. • Global and friend-only leaderboards that refresh automatically after every match. Under the hood I’ll need a lightweight, scalable backend—Firebase, Supabase, or a Node.js + WebSocket stack all work as long as matchmaking is smooth and rankings update in real time. The codebase should be clean, well-documented, and structured so additional mini-games can slot in later without rewriting core services. Acceptance criteria for delivery: 1. Users can create an account, enter matchmaking, and complete a live puzzle round against another player without crashes or noticeable lag. 2. Win/loss, score, and rank update immediately and display correctly in the profile and leaderboard. 3. Build runs on current Android devices (minimum SDK 24). An iOS build is a welcome bonus but not essential for this milestone. 4. Source repository, setup instructions, and brief technical docs are handed over so I can keep extending the app. If you’ve shipped real-time multiplayer titles or have sample code using Firebase, WebSockets, or similar tech, share it—I’m eager to see proven approaches before we dive in. check refrence app :- https://play.google.com/store/apps/details?id=com.jiyanshi.tictactoe
