Project Summary
BLXINO is a fully functional crypto casino built and operated entirely solo. No frontend team. No backend team. No designers. No DevOps.
From architecture to live incident handling, every system was designed, implemented, and maintained by me while serving thousands of real users with real money on the line. This project demonstrates end-to-end system ownership across frontend, backend, real-time infrastructure, game physics, security, and production operations.
Core Features
Real-time crypto deposits & withdrawals with live betting feed and in-app chat powered by Socket.IO. Four original games: Crash, Roulette, Mines, and Dice with multiplier-based game logic.
Custom design system with animations, server-authoritative game outcomes for provable fairness, and production-grade monitoring & logging. The entire platform handles concurrent users with low-latency updates and race condition prevention.
Key Challenge:
Deterministic Physics
The backend determines game outcomes (e.g. 0.3x multiplier), but Matter.js physics is non-deterministic. The visual result had to look random, be physically realistic, and always match the server result. Initial frame-by-frame replay approach generated ~6,000 frames per ball with high memory cost.
Final Solution: I controlled initial physics parameters (position, velocity, friction, restitution) instead of outcomes. Pre-generated multiple physics configurations that reliably land on the same multiplier. When the backend returns 0.3x, a random configuration from that pool is selected. Result: natural physics, server-authoritative outcomes, zero replay data, fully scalable.
Results & Impact
~300 users first week • 3,000+ users first month • Strong early revenue • Stable production performance
