Sweep Stake - Wheel Game

Gamification Platform with Admin Portal

Executive Summary

The Situation:A marketing SaaS company required a white-label gamification engine (spin-the-wheel) that other vendors could subscribe to and deploy to their own customers.
The Mandate:Architect a complex multi-tenant system: a highly interactive Flutter frontend for end-users, and a robust Next.js admin portal for vendors to customize their game mechanics and pay subscriptions.
The Result:Delivered a massive, engaging SaaS ecosystem that generated immediate recurring revenue for the client through B2B vendor subscriptions.

Technical Deep-Dive

Overcoming Bottlenecks

Engineering a secure, un-hackable wheel-spinning physics engine in Flutter where the outcome was determined securely by a backend API rather than client-side manipulation.

First-Principles Engineering

Built a cryptographic RNG (Random Number Generator) on the backend API. The Flutter app simply rendered the buttery-smooth rotation physics based on the secure, pre-determined API response, eliminating cheating entirely.


Business Impact

B2B Monetization

Integrated Stripe billing to handle automated vendor subscriptions seamlessly.

White-Label Scale

The Next.js dashboard allowed vendors to dynamically upload logos and change game parameters without developer intervention.

Cross-Platform Gaming

Flutter delivered 60fps native performance, making the gamification feel premium and addictive.
