Slot Industry Business Glossary: Operations & Distribution Terms Explained
The slot industry isn’t just about RTP and Free Spins. For game providers, operators, and distributors, there’s an entire B2B vocabulary that drives the business. This article breaks down the essential terms.
1. Core Revenue Metrics
GGR (Gross Gaming Revenue)
GGR = Total Bets − Total Wins
The most fundamental metric for measuring how much a game or platform earns. GGR is essentially the money players lose. Most industry reports reference GGR.
Example: A game generates $1,000,000 in total bets in a month, players win back $960,000. GGR = $40,000.
NGR (Net Gaming Revenue)
NGR = GGR − Bonus Costs − Taxes − Provider Fees − Payment Processing
NGR is what the operator actually keeps. Typically 50%–70% of GGR, depending on tax rates and bonus strategy.
Turnover / Handle
Total amount wagered by players, before deducting wins. A volume metric used to gauge game activity rather than profitability.
Bet Count
Total number of spins. Combined with Turnover, you can calculate Average Bet — a key metric for player behavior analysis.
ARPU (Average Revenue Per User)
Average revenue per user, typically monthly = Monthly GGR ÷ Monthly Active Users. Social casino ARPU is ~$0.5–$3; real-money casinos can hit $50–$200+.
LTV (Lifetime Value)
Total expected GGR from a player from registration to churn. LTV determines the upper bound for acquisition budgets (CPA).
CPA (Cost Per Acquisition)
Cost to acquire one new registered/depositing player. Real-money casino CPAs in SEA run $5–$30; in Europe, $100–$300.
Rev Share (Revenue Share)
An affiliate model where the promoter earns a percentage of the GGR generated by referred players (typically 25%–45%), rather than a fixed CPA.
2. Game Distribution Terms
Provider / Supplier
Companies that develop slot games. Examples: Pragmatic Play, PG Soft, JILI, NetEnt, Play’n GO. Providers deliver games to operators via API.
Operator
The player-facing platform. Operators hold licenses, process payments, manage users, and provide support. Examples: bet365, Stake, BingoPlus.
Aggregator
The middleware layer connecting providers and operators.
Operators can’t integrate dozens of provider APIs one by one. Aggregators bundle multiple providers into a unified API — one integration, hundreds of games.
Notable aggregators: SoftSwiss, EveryMatrix, SlotGrator, SoftGamings.
GAS (Game Aggregation System)
The aggregator’s core tech product. Provides unified wallet interfaces, game launch endpoints, and transaction logs.
Integration
The technical process of connecting a provider’s or aggregator’s games to an operator’s platform:
- Seamless Wallet: Games call the operator’s balance API directly
- Transfer Wallet: Player funds transfer into the game platform first, then back
RGS (Remote Gaming Server)
The server-side infrastructure deployed by providers. Handles game logic, RNG computation, and outcome generation. The operator’s frontend calls the RGS via API.
Game Lobby
The page on an operator’s site displaying all available games. Typically supports filtering by provider, type, popularity, RTP, etc.
Game Launch URL
The URL provided by aggregators or providers to load a game in an iframe or new window. Usually carries parameters like token, language, and currency.
W2A (Web-to-App)
A distribution strategy that funnels web users into installing a native app.
Since Google Play and the App Store heavily restrict real-money gambling apps, operators use web landing pages to guide users to download APKs (Android) or provisioning profiles (iOS). The typical flow:
- User clicks a promo link → arrives at W2A landing page
- Page detects device type (Android/iOS)
- Android: direct APK download or redirect to third-party store
- iOS: guide to install enterprise-signed app or TestFlight
W2A pages are often designed to mimic Google Play / App Store layouts to build trust. This is the dominant distribution method in Southeast Asia and Latin America.
PWA (Progressive Web App)
A web page disguised as an app.
PWA is a web application that can be “added to home screen,” looking and feeling like a native app while actually running in the browser.
Advantages:
- Bypasses app store review: No need to list on Google Play / App Store
- Instant updates: No user-side version updates required
- Cross-platform: One codebase for iOS + Android
- Low cost: No native client development needed
Disadvantages:
- Limited functionality on iOS (push notifications, background processes restricted by Safari)
- Performance inferior to native apps
- Some users unfamiliar with “Add to Home Screen”
In the gambling industry, PWA is the lightest distribution option. Many Philippine and Indian operators run their main platform as a PWA.
Native App
Apps built with Swift/Kotlin for iOS/Android natively. Best performance and smoothest UX, but high development cost, and gambling apps face extremely strict app store review (rejected in most regions).
Typically only large licensed operators (e.g., bet365, PokerStars) manage to list real-money gambling apps on Google Play / App Store, and only in specific regions.
Hybrid App
A native app shell that loads web content via WebView internally. Combines the native “shell” (can be listed on stores, push notifications) with web flexibility (content updates anytime).
The gambling industry uses Hybrid extensively: the app shell passes store review, while the web content loaded inside can be switched at any time.
APK Distribution (Sideloading)
Android allows users to install APK files from outside Google Play. Operators provide APK downloads directly from their websites — the most straightforward way to bypass app store restrictions.
Risks: Users must manually enable “Install from Unknown Sources,” and Google Play Protect may block installation. Operators typically need to provide detailed installation tutorials on the landing page.
Enterprise Certificate / Enterprise Signing (iOS)
A distribution method that bypasses the App Store on iOS. Apps signed with Apple Enterprise Developer Certificates can be installed directly without listing.
Issue: Apple periodically revokes abused enterprise certificates (known as “certificate revocation”), causing apps to stop opening. Operators need multiple certificates on rotation, or guide users to PWA as a fallback.
TestFlight
Apple’s official app testing distribution channel. Supports up to 10,000 external testers per app. Some operators use TestFlight to distribute gambling apps, but Apple is tightening review on this channel.
Deep Link
A link that doesn’t just open an app, but navigates directly to a specific page within it. E.g., clicking a promo link → opens app → lands directly on a specific game. Deep links are critical for improving conversion rates.
Common implementations:
- Universal Links (iOS) / App Links (Android): System-level, best experience
- URI Scheme (e.g.,
myapp://game/123): Fallback approach - Deferred Deep Link: If user hasn’t installed the app, guides installation first, then auto-navigates to the target page after install
OTA (Over-the-Air) Updates
Technology allowing apps to push updates without going through app stores. Common solutions:
- Hot Update: Update JS/HTML resources without reinstalling the app
- CodePush (React Native) / Tinker (Android) frameworks
Especially important for gambling apps — avoids resubmitting to store review for every change.
Landing Page
The first page a user sees after clicking an ad or promo link. In the gambling industry, the core goal is driving registration or download.
Key elements of a good landing page:
- Clear CTA (Call to Action) above the fold
- Page load time < 3 seconds
- Customized versions for different channels (Facebook, Google, Telegram)
- A/B testing to optimize conversion
Smart Link
A link that auto-redirects to different destinations based on user device, region, or source. For example:
- Android user → APK download page
- iOS user → PWA guide or TestFlight
- User with app installed → Deep Link to open app directly
- User in blocked region → Backup domain
Domain Rotation
Gambling promo links getting banned by social platforms or search engines is routine. Domain rotation strategy: maintain a pool of domains, dynamically switch via a short-link system, and activate the next one the moment one gets blocked.
3. Business & Commercial Terms
B2B vs B2C
- B2B (Business to Business): Provider sells games to operator
- B2C (Business to Consumer): Operator sells entertainment to players
- Some companies do both (e.g., Pragmatic Play supplies games and operates brands)
Revenue Model
How providers charge operators:
| Model | Description | Typical Range |
|---|---|---|
| GGR Share | Percentage of game GGR | 10%–20% |
| Fixed Monthly Fee | Flat monthly access fee | $500–$5,000/mo |
| One-Time Buyout | Full game ownership (common in Asia) | $10,000–$50,000/game |
| Hybrid | Fixed fee + low GGR share | Varies |
White Label
Operator purchases a ready-made casino platform (including license, payments, games) and brands it as their own. Ideal for quick launch without a tech team.
Turnkey Solution
More complete than white label: includes branding, website build, payment channels, game integration, and compliance documentation. Turnkey = you get the keys and open for business.
Sub-License
Operating permission granted under a primary license holder. Some B2B platforms allow clients to operate under their license, saving time and cost of obtaining a separate one.
Exclusive / Non-Exclusive
Game distribution agreements:
- Exclusive: A game launches only on a specific operator for a period (typically 1–6 months)
- Non-Exclusive: All operators can integrate
Exclusivity is a bargaining chip for large operators and a promotional tool for providers.
4. Compliance & Licensing Terms
License
The permit required to legally operate an online casino. Different jurisdictions offer different credibility and requirements:
| License | Jurisdiction | Difficulty | Annual Cost |
|---|---|---|---|
| MGA | Malta | High | €25,000+ |
| UKGC | United Kingdom | Very High | £10,000+ |
| Curaçao | Curaçao | Low | $10,000–$20,000 |
| PAGCOR | Philippines | Medium | Varies |
| Isle of Man | Isle of Man | High | £35,000+ |
| Kahnawake | Canada | Low | $10,000+ |
GLI / eCOGRA / BMM / iTech Labs
Third-party testing labs that certify game RNG fairness, RTP accuracy, and technical compliance. Games must pass certification before going live.
Responsible Gambling
Player protection measures required by regulators:
- Self-Exclusion
- Deposit Limits
- Cooling-Off Periods
- Reality Checks — periodic reminders of time spent playing
KYC (Know Your Customer)
Identity verification process. Operators must verify player identity to prevent money laundering. Typically requires ID documents, proof of address, and payment verification.
AML (Anti-Money Laundering)
Operators must monitor for suspicious transaction patterns (e.g., large deposits immediately followed by withdrawals) and report suspicious activity to regulators.
5. Product & Operations Terms
PAR Sheet (Probability and Reel Sheet)
The mathematical design document for a game. Records symbol distribution per reel, pay tables, RTP calculations, hit frequency, and more. This is a provider’s core trade secret.
Hit Frequency
The probability of a player winning any prize on each spin. Typical range: 20%–35%. Note: high hit frequency ≠ profit — many “hits” just return part of the bet.
Math Model
A game’s mathematical design defining RTP, volatility, symbol weights, payout structure, and bonus trigger probabilities. The math model determines how a game “feels.”
Certification
Pre-launch testing by third-party labs. Covers RNG testing, RTP verification, rule accuracy, and technical security. Different markets require different certifications.
Localization
Adapting games for different markets: translating UI text, adjusting currency display, modifying compliance notices, and even adjusting art style (e.g., Asian markets prefer gold and red themes).
Go-Live
The moment a game moves from testing to production. Pre-Go-Live typically requires: integration testing, UAT, certification approval, and compliance review.
Staging / UAT
Pre-Go-Live testing phase. Operators verify game functionality, payment flow, and display in a staging environment before real money goes live.
6. Marketing & Acquisition Terms
Bonus
Marketing tools operators use to attract and retain players:
| Type | Description |
|---|---|
| Welcome Bonus | First deposit match, e.g., “100% up to $500” |
| No Deposit Bonus | Small bonus requiring no deposit |
| Free Spins | Free spins on specific games |
| Cashback | Refund based on net losses over a period |
| Reload Bonus | Bonus on subsequent deposits |
| VIP/Loyalty | Points, tiers, and exclusive rewards |
Wagering Requirement / Playthrough
The number of times a bonus must be wagered before withdrawal. “30x Wagering” on a $100 bonus = must bet $3,000 before cashing out.
Conversion Rate
Key funnel metrics:
- Visitor → Registration: 5%–15%
- Registration → FTD: 20%–40%
- FTD → Repeat Deposit: 30%–50%
FTD (First Time Deposit)
First deposit by a new player. One of the most closely tracked acquisition metrics. FTD count × ARPU = projected revenue.
Retention
Keeping players coming back. Key metrics: D1 (next-day), D7 (7-day), D30 (30-day). Real-money casino D30 retention typically runs 15%–30%.
Affiliate
Third-party partners (websites, KOLs, communities) that promote platforms. Affiliate marketing is one of the primary acquisition channels for online casinos, typically settled via CPA or Rev Share.
7. Technical Infrastructure Terms
Wallet
The backend system managing player funds. Core requirements: high concurrency (thousands of transactions per second), strong consistency (no balance errors), and full audit trails.
Back Office
The operator’s admin panel. Features include: player management, transaction queries, risk management, reporting, bonus configuration, and access control.
Payment Gateway
Middleware connecting operators to payment channels (cards, e-wallets, crypto). Different regions need different channels (Philippines = GCash/Maya, Brazil = PIX, India = UPI).
CDN (Content Delivery Network)
Game assets (images, audio, animations) distributed via global CDN nodes to reduce load times. Critical for operators serving multiple regions.
Lobby API
API for operators to fetch game lists, thumbnails, and category data. Aggregators typically provide standardized Lobby APIs that operators use to build their game halls.
Summary
Understanding these terms means understanding how the slot industry actually works:
- Providers build games → focus on Math Model, PAR Sheet, Certification
- Aggregators distribute → focus on Integration, GAS, Lobby API
- Operators make money → focus on GGR, NGR, CPA, LTV, Retention
- Regulators enforce rules → focus on License, KYC, AML, Responsible Gambling
It’s a business built on mathematics, driven by technology, and bounded by compliance. Master these terms and you can read industry reports, understand deal negotiations, and spot unreliable operators.
