NGR (Net Gaming Revenue)
GGR minus bonuses, provider fees, payment and tax costs. Reflects real profitability.
RTP (Return to Player)
The share of wagers a game returns to players over the long run. 97% RTP means a 3% house margin. Configurable per game.
House edge
The operator’s mathematical advantage, equal to 100% minus RTP. Drives expected game profitability.
Wagering requirement
The number of times a bonus must be wagered before withdrawal. Controlled by per-game weights, a maxBet limit and a max cashout (maxConversion).
Provably fair
A method to cryptographically verify a game result: the server publishes a SHA-256 hash of the seed before the round and reveals it after, so players can re-check the outcome.
RNG (Random Number Generator)
The algorithm that determines game outcomes. In provably-fair games it can be verified via the seed.
Seamless wallet
An architecture where a single player balance is used by all games and providers with no transfers between wallets. Bet/win/rollback operations are idempotent.
Game aggregator
A layer that unifies many providers’ catalogs (Pragmatic Play, Evolution, etc.) under a single launch and settlement API.
KYC (Know Your Customer)
Player identity verification by tiers: from an age check to documents, liveness, address and screening. Required for withdrawals and compliance.
AML (Anti-Money Laundering)
Procedures to detect suspicious activity: deposit threshold checks, flagging and escalation to a compliance officer.
PEP (Politically Exposed Person)
A higher-risk client requiring enhanced due diligence (EDD) and source of funds. Detected during screening.
Sanctions screening
Checking a player against sanctions lists, PEP and adverse-media. Implemented via providers (ComplyAdvantage, Refinitiv) behind a swappable interface.
Responsible Gaming
Player-protection tools: deposit, loss, bet and session limits, reality check, cool-off and self-exclusion.
Self-exclusion
A player’s ability to voluntarily block their own access — temporarily or permanently. A mandatory RG tool.
Cool-off
A short enforced break from play that a player can enable themselves. Softer than self-exclusion.
Reality check
A periodic reminder of session length and results that helps a player control their time.
Risk scoring
A 0–100 player risk score from weighted rules (VPN, geo mismatch, multi-accounts, etc.) with low/medium/high bands.
Identity graph
Links between players by device, IP and payment instrument to detect multi-accounts and fraud rings.
Parlay (accumulator / express)
A bet on several events where all outcomes must win; the odds are multiplied.
System bet
A k-of-n combination: the bet can win partially even if not all outcomes hit.
Handicap
A virtual advantage/deficit added to a team’s final score to settle the bet.
White Label
Launching a ready platform under the operator’s brand, with the provider running infrastructure and updates.
Turnkey
A complete solution with the platform, license and payment help, and a dedicated environment.
Multi-tenancy
An architecture serving multiple operators/brands with data isolation (schema-per-tenant) and a shared core.
Revenue share
A pricing model where the provider takes a percentage of the operator’s GGR (default ~5%).
GGR vs NGR — the difference
GGR is revenue before deductions (wagers minus winnings). NGR is what remains after bonuses, provider fees, payment and tax costs. NGR is always lower than GGR and better reflects profit.
Hold
The share of total wagered volume the casino keeps as revenue. Conceptually close to house edge but measured on actual turnover over a period.
Free spins
Bonus slot spins funded by the operator. Winnings are usually credited as bonus funds subject to a wagering requirement.
Bonus abuse
Exploiting promotions via multi-accounts, collusion or low-risk wagering. Detected with a linkage graph, risk scoring and withdrawal gates.
Chargeback
A forced deposit reversal via the bank/PSP initiated by the player. A loss driver and fraud signal; reduced via KYC and risk rules.
Master & sub-license
A master license is held by an entity that issues sub-licenses to operators. It lets an operator go live faster under a White Label umbrella.
Geo-fencing
Restricting platform access by country/region per the license and block-lists. Enforced at registration and payment level.
Source of funds (SoF)
Proof of where a player’s money comes from, part of enhanced due diligence (EDD) at a high KYC tier — required for PEP and high-risk.
EDD (Enhanced Due Diligence)
Extended checks for higher-risk customers: source of funds, additional documents and ongoing monitoring.
Churn & retention
Churn is the share of players who stop playing over a period. Retention is the inverse; gamification and bonuses directly affect both.
