Questions about Slots API integration and operations
Browse the existing industry questions by category, or search all guides and questions together above.
Industry Q&A
What is a slot game, and how do online slots work?
A slot is a probability-based game built around reels, symbols and winning rules. When a player starts a valid round, the game system uses that version's mathematical model and a random-number result to select the symbol outcome and calculate any payout.
Industry Q&AWhat is the difference between classic, video and progressive-jackpot slots?
Classic slots usually have simpler reels and mechanics. Video slots place more emphasis on themes, animation, win mechanics and bonus features. Progressive-jackpot slots add eligible stakes to a growing prize pool until the trigger conditions are met.
Industry Q&AWhat is slot RTP, and why is theoretical RTP not an individual return?
RTP, or return to player, is the percentage of total stakes a game is expected to return across a very large number of rounds under a defined version and rule set. It is a long-run statistical measure, not a promise for one player, session or short period.
Industry Q&AWhat is slot volatility, and how do high and low volatility differ?
Volatility describes how win amounts and intervals are distributed. High-volatility games tend to have less even win intervals and larger swings per result, while low-volatility games tend to produce smaller wins more frequently.
Industry Q&AWhat is the difference between hit frequency, RTP and volatility?
Hit frequency measures how often any winning result occurs; RTP estimates the long-run percentage of stakes returned; volatility describes the variation in win size and timing. They measure different characteristics and cannot replace one another.
Industry Q&AWhat is a slot RNG, and how does it produce game outcomes?
An RNG, or random number generator, continuously produces random values. Each valid game request maps the relevant value to an outcome defined by that game version; normally, each round is independent and the previous result does not determine the next one.
Industry Q&AWhat are free spins, bonus rounds and bonus-buy features?
Free spins are additional spins awarded when stated conditions are met. A bonus round is a separate feature outside the base game. A bonus buy lets a player pay the amount defined by the game rules to enter a specified feature directly.
Industry Q&AWhat is the difference between fixed and progressive jackpots?
A fixed jackpot pays an amount set by the game rules and does not grow continuously with participation. A progressive jackpot accumulates according to defined rules until its trigger is met, then pays and resets or returns to a base amount.
Industry Q&AWhat are reels, paylines and win mechanics?
Reels are the vertical columns that carry symbols. Paylines are predefined paths used to evaluate symbol combinations. Win mechanics define which positions, symbol counts or patterns create a win; a slot may use lines, ways-to-win or adjacent clusters.
Industry Q&AWhat do wild and scatter symbols do?
A wild symbol usually substitutes for specified regular symbols when the rules allow it, helping to complete winning combinations. A scatter usually awards a prize or triggers a feature based on how many appear and may not be limited to a fixed payline.
Industry Q&AWhat is the difference between demo and real-play modes?
Demo mode normally uses a virtual balance that cannot be withdrawn and is intended for reviewing presentation and basic mechanics. Real play connects an authenticated player account, wallet and transaction records. Their identity, funds and transaction responsibilities differ.
Industry Q&AHow can a platform review a slot game's fairness testing?
Match the test report or certificate to the exact provider, game name, version, mathematical model or RNG scope and intended market. Check the issuing laboratory, reference number, date and current status.
Industry Q&AWhat does a game provider do, and how do providers differ?
A game provider designs, develops and maintains game content, including visuals, mechanics, mathematical models, versions and provider-side services. Providers differ in themes, mechanics, device experience, languages, currencies, release cadence and integration rules.
Industry Q&AWhat is a game aggregator, and how can one API connect multiple providers?
A game aggregator sits between an operator platform and multiple game providers, translating their catalog, session, wallet-transaction and record rules into one integration model. The operator can therefore connect and manage content from several providers through one API.
Industry Q&AWhat is the difference between a game provider, aggregator and operator platform?
A provider creates and maintains games; an aggregator connects multiple providers through a unified interface; an operator platform manages its player-facing brand, accounts, wallet, payments, operations and support. They participate in one delivery chain but have different responsibilities.
Industry Q&AWhat is the difference between a game API, white label and full operator platform?
A game API connects catalog, launch, wallet and record functions to an existing system. A white-label solution usually adds configurable front-end and back-office functions. A full operator platform also covers broader systems such as accounts, payments, promotions and customer support.
Industry Q&AWhat is the difference between game language, game currency and platform payment methods?
Game language controls the interface and rule text. Game currency is the accounting unit used for sessions, balances and transactions. Platform payment methods handle user deposits and withdrawals. Support for one does not automatically imply support for the others.
Industry Q&AWhy can the same slot game have different availability by region?
Availability can depend on provider delivery scope, game version, language and currency, commercial scope and target-market requirements. A title available in one region is therefore not automatically available in another.
Industry Q&AWhen should a platform integrate providers directly or use an aggregator?
Direct integration suits platforms that need a small number of core providers and can maintain separate commercial and technical relationships. Aggregation suits platforms that want one interface for multiple providers and less repeated development and maintenance.
Industry Q&AHow should a business choose between an aggregation API, white label and full platform?
A business with its own account, wallet and operating systems will usually assess an API first. A team seeking configurable front and back offices may assess white label. A project needing complete account-to-payment capabilities should assess a full platform.
Industry Q&AWhat should a platform compare when choosing a game aggregator?
Compare the providers and games actually available, API and wallet models, transaction reliability, reports and reconciliation, languages and currencies, performance, maintenance, support, pricing definitions and project-specific evidence.
Industry Q&AHow should a platform select providers and a game mix for a target market?
Define target regions, languages, currencies, common devices and content preferences, then combine familiar providers, varied themes, volatility ranges, bonus mechanics and both established and new titles.
Industry Q&AWhat matters beyond the number of games?
Review launchable coverage, target-market fit, mobile loading, version stability, rule and asset completeness, content updates, maintenance notices, transaction success, record traceability and support response.
Industry Q&AHow can a platform verify language, currency and device support?
Build a target-market matrix and verify interface and rule languages, currency codes and amount precision, mobile and desktop browsers, in-app launch behavior and each game version's actual performance.
Industry Q&AWhat fees commonly appear in game aggregation services?
Common items include one-time setup fees, monthly minimums or service fees, revenue share calculated on a defined base such as GGR, prepaid balance, and fees for selected providers, functions or custom work.
Industry Q&AWhat are GGR and NGR, and how should a contract define them?
GGR commonly means stakes minus player winnings. NGR commonly deducts additional contract-defined items from GGR, but there is no universal deduction list that applies to every agreement.
Industry Q&AWhat should be tested before launch, and what are the usual stages?
The usual sequence is requirements confirmation, test access, catalog and session integration, wallet and failure scenarios, report reconciliation, device and localization checks, launch acceptance and production configuration.
Industry Q&AWhich providers, games, languages and currencies does AG GAME support?
AG GAME currently aggregates 11 providers: PGSoft, Pragmatic, Evoplay, CP Games, WG Games, JILI, TADA, JDB, FC, BG and HSD, with a business catalog position of 1,200+ slots.
Industry Q&AWhat are AG GAME's integration requirements, pricing structure and test process?
Applicants should provide company and project details, target regions, estimated volume, required providers and games, languages and currencies, existing platform and wallet model so AG GAME can confirm scope, quote and testing.
Industry Q&AHow does AG GAME support content updates, reports and incidents?
AG GAME synchronizes game content and status through unified interface and management capabilities, provides game and transaction record queries, and offers 24/7 technical support for integration or runtime incidents.
Industry Q&AWhat is the difference between single-wallet and transfer-wallet models?
In a single-wallet model, the operator owns the player's main balance and the game side calls it for bets and payouts. In a transfer-wallet model, funds move into a game-side wallet first and return through a separate transfer workflow.
Industry Q&AWhat is the end-to-end flow for listing and launching a game?
Synchronize providers, categories and games; confirm availability; create a session with merchant, player, game, language, currency and return parameters; then pass the launch result to the front end.
Industry Q&AHow do balance, bet, payout and rollback transactions work together?
The game side queries available balance when needed, an accepted bet debits the operator ledger, and the result produces a payout. A rollback references the original transaction and creates a traceable state change.
Industry Q&AHow should duplicate debits or payouts be prevented?
Assign each business transaction a stable unique ID and enforce uniqueness in the ledger. Repeating that ID must return the original business result without changing the balance again.
Industry Q&AWhat should happen after a timeout, disconnect or interrupted game?
A timeout means the caller did not receive a definitive result in time; it does not prove failure. Query or reconcile the original transaction before deciding to retry, roll back, compensate or await round settlement.
Industry Q&AHow should transaction and round IDs be used for reconciliation?
Use the unique transaction ID to locate one ledger entry, the round ID to group bets, payouts, rollbacks and compensation, then reconcile both reports under the same currency, time zone and status rules.
Industry Q&AHow should currency codes, amount precision and settlement currencies be handled?
Agree currency codes, minor units, decimals, rounding and availability. Use integer minor units or fixed decimal arithmetic rather than binary floating point for money.
Industry Q&AHow should API latency, game load time and concurrency be measured?
API latency covers request-to-response time, game load time covers launch-to-interaction experience, and concurrency measures correctness and target latency under a stated request volume and business mix.
Industry Q&AWhat can a global CDN improve, and what latency remains elsewhere?
A CDN places cacheable images, scripts and other static assets closer to users. Dynamic sessions, wallet transactions and provider services still reach origin or business systems.
Industry Q&AHow should API signing, keys, access and data separation be implemented?
Use cryptographic signatures to verify origin and integrity, constrain credential purpose and environment, and separate test and production merchants, keys, data and logs. Never place secrets in front-end code or public repositories.
Industry Q&AHow should provider incidents, maintenance and recovery be handled?
Distinguish game, provider, aggregation, wallet and network failures; disable or degrade only the known impact scope, communicate status, and verify final transactions before restoring entry points gradually.
Industry Q&AHow should API upgrades or aggregator migration handle compatibility and open transactions?
Freeze current mappings, build a compatibility matrix and rollback conditions, validate with test traffic, then move new sessions in stages while the old path completes existing sessions and rounds.
Industry Q&AHow should game source, availability and supporting evidence be verified?
Start with the required provider, game, version and target-region list. Confirm the content source chain, available scope, validity and restrictions, and match any agreement, provider confirmation or test material to that list.
