SLOT GAME

A complete slot game loop with bankroll management, cascade wins, free-spin retriggers and cryptographically verifiable fairness.

Go Vue.js PixiJS PostgreSQL Redis

The Challenge

Slot games demand mathematically verified fairness, complex cascade mechanics and a certified payout target while staying fun and smooth.

Our Solution

A Go (Fiber) backend handles game logic with PostgreSQL sessions and Redis state; a Vue + PixiJS frontend renders animations via GSAP. Fairness uses crypto/rand with an audit trail, verified through Monte-Carlo RTP simulation.

Key Features

5x4 grid with up to 1,024 ways to win
Cascade mechanics with symbol tumble and chained wins
Progressive multiplier ladder in base and free-spin modes
Free-spins bonus with scatter triggers and retriggers
Provably-fair RNG with cryptographic verification
Certified 96.92% RTP validated by Monte-Carlo simulation
