hizi engine

Generate, test and serve slots, instant wins, scratch cards, and more.

Generate

Convert your game engine's simulation results into compact JSONL files. Automatic entry merging, scenario limiting, and streaming writes to disk.

Generator

Serve

The hizi RGS platform serves pre-computed outcomes to players. Weighted RNG selection, multi-step scenarios, free spins, buy-features, and certified audit trails.

How it works

Integrate

Four essential SDK calls drive the game lifecycle - login, loadConfig, placeBet, collect. Type-safe helpers for HTTP and WebSocket communication.

SDK Getting Started

Multi-step Scenarios

Built-in support for advanced features like hold and win and feature-progression. The engine tracks game state across sequential placeBet calls.

Certified & Auditable

File hash verification, RNG audit trails, and deterministic outcome selection from weighted entry pools. Designed for regulated markets.

Compact Database Format

Compressed JSONL files for entries and scenarios. Streams directly to disk during generation - no memory accumulation for large datasets.

For LLMs

This site provides an llms.txt index following the llmstxt.org standard — a structured list of every page in the docs, optimised for ingestion by large language models. Point your LLM (or agent tooling) at https://docs.hizi.io/engine/llms.txt to give it a map of the docs.
