What is hizi engine? ​

hizi engine is a system for building and serving pre-computed game outcomes for fixed-odds games - slots, instant wins, scratch cards, and more.

How It Works ​

        +-- uses @hizi.io/engine-sdk
  1. Generate - Your game engine simulates millions of outcomes. hizi engine generator streams them into compact JSONL files.
  2. Deploy - The output files are deployed to the hizi RGS platform, which serves outcomes to players at runtime.
  3. Play - Your frontend calls login, loadConfig, placeBet, and collect using the hizi engine SDK. The engine selects outcomes from the weighted entry pool using certified RNG.

What hizi engine Handles ​

  • Outcome selection - Weighted random selection using certified RNG
  • Game state - Multi-step scenarios, free spins, bonus rounds
  • Balance management - Debit/credit through the hizi RGS platform
  • Session management - Token-based authentication and lifecycle
  • Buy-feature pricing - Automatically calculated from entry data
  • Certification - File hash verification and RNG audit trails
  • Compact storage - Brotli-compressed JSONL files for entries and scenarios

What You Build ​

  • Game engine - Simulates outcomes offline (reels, wins, bonuses)
  • Frontend client - Visual game interface (HTML5, React, Unity, etc.)
