Why operators delay launch

Three ways uncertifiable games kill your roadmap

01

RTP variance fails GLI-19 statistical tests

Your studio ships a slot with 96.2% theoretical RTP, but the simulation log shows 96.8% over one billion spins. The certifier flags non-compliance and you rebuild the entire paytable logic under time pressure.

02

RGS integration breaks state persistence

A player disconnects mid-spin. Your game client reconnects but the server has no record of the bonus round state. You cannot prove game fairness and the regulator suspends your certificate of approval.

03

RNG seeding violates GLI-11 entropy requirements

Your developer uses a timestamp-seeded PRNG instead of a hardware entropy source. The certifier’s cryptanalysis detects predictable output sequences and rejects the entire RNG implementation.

How we work

Three engagement models for
different risk appetites

Choose fixed scope for predictable budgets, squad for ongoing content, or audit for pre-launch validation.

FIXED

Fixed-scope build

16 – 24 weeks
  • Defined game mechanic, art style and feature set agreed in week one
  • Milestone payments tied to math approval, alpha, beta and certification submission
  • Includes one RGS integration and one jurisdiction certification
  • Change requests priced separately after requirements freeze
  • Ideal for operators launching a flagship title or entering a new market
SQUAD

Dedicated squad

6 – 12 months
  • Two-week sprints with a math engineer, two developers and a QA specialist
  • Build multiple game variants or a portfolio of themed slots
  • Monthly certification submissions as each title reaches beta
  • Flexible backlog lets you pivot based on player data or competitor moves
  • Suits igaming software providers building a content library or live casino software solutions
AUDIT

Pre-certification audit

3 – 5 weeks
  • Independent review of your existing game math, RNG implementation and RGS protocol
  • Gap analysis against GLI-19, GLI-11 and target jurisdiction technical standards
  • Written report with remediation priorities and estimated certification timeline
  • Optional remediation sprint to fix critical issues before lab submission
  • Valuable for casino game companies inheriting legacy code or switching igaming platform providers

Casino affiliate tracking

Player attribution, revenue-share reporting, and campaign IDs compatible with casino affiliate marketing software.

Compliance and testing

GLI pre-certification review

Internal audit against GLI-11 and GLI-19 standards before formal submission to reduce iteration cycles.

Change management workflow

Version control, diff reports, and transfer-of-approval documentation for post-launch game updates.

Jurisdiction-specific builds

Configurable rule sets and compliance flags for Kahnawake gambling license, MGA, UKGC, and other markets.

Responsible gaming controls

Session timers, loss limits, and reality-check prompts embedded at the game-client level.

Payment and security

Cryptocurrency casino integration

Wallet connectors and blockchain transaction listeners for Bitcoin, Ethereum, and stablecoin deposits.

Igaming payment solution APIs

Pre-built adapters for igaming payment providers handling fiat deposits, withdrawals, and KYC verification.

Geolocation verification

IP and GPS checks to enforce territorial restrictions and comply with state-level licensing requirements.

Vault and safe evaluation

Secure key storage, encrypted session tokens, and audit trails that meet GLI cybersecurity standards.

Stack

Built for certification and scale

Every game we ship is architected to pass GLI review and integrate with your existing igaming platform provider infrastructure.

Unity

Cross-platform game engine for slot and table game rendering across desktop, mobile and retail betting client terminals.

Xorshift128+

Fast, deterministic PRNG for client-side animation and preview; all real-money outcomes are server-authoritative.

WebGL 2.0

Hardware-accelerated graphics API for browser-based casino games without plugin dependencies.

RESTful RGS API

Standard Remote Gaming Server protocol for spin requests, balance queries and session management with any b2b igaming software solutions backend.

JSON-RPC 2.0

Lightweight transport for live dealer casino software and real-time game state synchronization.

Redis

In-memory cache for session tokens, feature-state persistence and bonus-round continuity across reconnects.

PostgreSQL

Transactional store for game-round history, audit logs and paytable versioning required by igaming solutions providers.

Docker

Containerized build pipeline for reproducible test environments and simplified deployment to operator infrastructure.

Compliance

Certified math, auditable code

GLI-19

Interactive gaming systems

We structure game logic, RNG seeding and payout calculations to meet GLI-19 requirements for online casino certification. Source code is documented for third-party review and includes deterministic replay from server seeds.

RNG

Random number generation

All real-money outcomes are generated server-side using cryptographically secure RNGs that satisfy GLI-11 and jurisdictional entropy standards. Client animations reflect server results without influencing game mathematics.

RTP

Return-to-player verification

Paytable math is modeled in simulation suites that produce verifiable RTP reports. We deliver cycle-length documentation and variance profiles for submission to testing labs alongside the compiled game package.

RESPONSIBLE

Responsible gaming hooks

Games expose session-time counters, loss-limit triggers and reality-check overlays that igaming software providers can bind to operator-level responsible gaming policies and self-exclusion databases.

Questions from operators

What buyers ask before they sign

A certifiable slot game typically runs $80, 000 to $150, 000 depending on feature complexity and art requirements. That includes math model, RGS integration, GLI-19 compliance documentation, and one round of certification support.
You own both the source code and all game IP outright upon final payment. We transfer the repository, all assets, and math documentation with no ongoing licensing fees or restrictions.
We fix it at no additional cost if the failure is due to our math model or RNG implementation. You are responsible for costs if the failure stems from scope changes or third-party platform issues introduced after handoff.
Twelve to sixteen weeks for a standard slot game with original art and a tested math model. Table games and live dealer integrations add four to six weeks depending on the ruleset and streaming infrastructure.
We integrate with most established remote gaming servers including proprietary platforms. If your RGS lacks GLI-11 certification or proper API documentation, we can recommend b2b igaming software providers or build a lightweight RGS as part of the project.
We prepare all GLI-19 and GLI-11 compliance documentation and can coordinate directly with Gaming Labs International on your behalf. Final submission is typically done under your operator account, but we support the technical review process and respond to examiner queries.
Post-certification changes require re-submission under GLI change management procedures, which we handle as a separate scope. Minor paytable adjustments usually clear in two to four weeks; new bonus features trigger a full math review and longer timelines.
