My location-enabled mobile app is live on both stores, and now I’m expanding it with real-world, map-based games. The core infrastructure—GPS tracking, map rendering, groups, challenges and user accounts—is already in place. What I need now is the gameplay layer: Capture the Flag, chase-style pursuits and geo-cache hunts. The experience should stay simple and dynamic. A player, or a team, enters a game lobby, selects a mode and then watches live game elements—zones, flags, chasers or cache markers—appear on the map in real time. Interactions remain lightweight: tapping to claim a flag, dropping a virtual trail, scanning a QR or confirming a cache find. The focus is the outdoor gameplay, not a heavy UI. Your role is to architect the game logic, manage state synchronisation between nearby devices and the cloud, and integrate everything smoothly into the existing Flutter map screens. If you work comfortably with location-based SDKs, Mapbox or similar mapping stacks, AWS Amplify, custom WebSocket services or low-latency real-time frameworks, you’ll be a strong match. Performance and battery efficiency are key. Deliverables • Server-side and client-side modules for all three game modes • Real-time updates for both solo and team sessions • Leaderboard system (per city, per mode, and all-time) • Minimal but effective anti-cheat protections (GPS spoofing, duplicate cache claims) • Admin controls to enable or disable each mode by city Acceptance criteria • End-to-end demo with two test devices showing live flag capture, chase tagging and cache discovery • Leaderboard updates in real time as players earn points • Source code merged into the Git repository with clear setup documentation • Successful outdoor field test covering a 500-metre radius Once this game layer is complete, it will roll into the next app release and support the launch of outdoor tournaments. The goal is to get people outside, exploring and competing in a way that feels fun, active and intuitive

Hello, We can build the gameplay layer for your location app, adding Capture the Flag, chase pursuits, and geo-cache hunts with real-time sync, leaderboards, anti-cheat checks, and admin controls, integrated into your existing Flutter map screens. Quick clarifying questions, 1. Which realtime backend do you prefer, WebSockets on your own server, or a managed service (Firebase Realtime/Firestore, AWS AppSync)? 2. Should anti-cheat be lightweight server-side checks only, or include device attestation and heuristic detection? 3. Are tournament rules and scoring fixed now, or should we expose configurable rule-sets per city from day one? Our engineers build realtime mobile game systems, location logic, Mapbox and geofencing integrations, and battery-efficient client code, we deliver server and client modules, demo scripts, and field-test support. Let’s schedule a short alignment, so I can propose milestones and a rapid prototype, the current bid is a placeholder to submit. Regards, Yasir LEADconcept PS: I can share relevant location-game demos and leaderboard integrations on request.

Hello, I can plug this gameplay layer directly into your existing Flutter + map stack and handle both the real-time game logic and backend sync. I’ve worked with location-based apps, Mapbox-style SDKs, WebSockets/AWS Amplify, and know how to keep GPS-heavy features responsive without draining the battery. I’ll design modular server- and client-side code for Capture the Flag, chase modes, and geo-cache hunts, including lobby flow, live map elements, and lightweight interactions (taps, QR scans, trails). I’ll also implement per-city leaderboards, basic anti-cheat checks (spoofing, duplicate claims), and admin toggles for each mode, then prove everything in an outdoor test with multiple devices. All code will be merged into your repo with clear setup docs so you can ship it in the next release and scale to tournaments easily. Best regards, Juan

Hi there, I'd love to help bring these real-world, map-based game modes to life — your existing GPS + mapping foundation is a perfect base for fast, dynamic outdoor gameplay. I’ve worked extensively with Flutter, Mapbox, AWS Amplify, and low-latency real-time systems (WebSockets, MQTT), and I’ve built location-driven games and group-tracking features with strong performance + battery efficiency—exactly what this project requires. Here’s how I’d approach your three game modes: - Capture the Flag / Chase / Geo-Cache: modular game-state engines, cloud-synced, with client-side prediction for smooth map updates. - Real-time Sync: WebSocket channels per lobby with differential updates so devices only receive changed state. - Leaderboards: Amplify backend or custom Lambda functions, city/mode/all-time scoring. - Anti-Cheat: GPS drift detection, spoofing checks, cool-downs, and server-verified claims. - Admin Tools: mode toggles + region rules integrated into your existing backend. Quick Questions: - Is your current real-time layer on Amplify, custom sockets, or Firebase? - Do you have gameplay wireframes, or do you prefer our team to propose the UX? - Should modes support matchmaking or only manual lobby creation? Happy to walk through the architecture and timeline on a quick call—this feature set is right in my wheelhouse and ready to execute.

Hi Evan I’ve spent a good while reading through your brief, and what stands out is that you’re not just adding “features” – you’re trying to create a clean, low-friction layer of outdoor gameplay that behaves reliably in the real world. That calls for tight state sync, predictable GPS handling and logic that doesn’t drain a phone after half an hour. I’ve built Flutter map experiences before with Mapbox and AWS-backed real-time services, and I’m comfortable designing the kind of lightweight, event-driven gameplay these modes need. One thought: treating each mode as a modular “game session” will keep future tournaments flexible. Happy to walk you through an approach if you’d like. Kind regards Henry
