Gamevy - Overview and Integration

Overview

Gamevy specializes in instant win and arcade/crash content, complementing the portfolio with scratch cards, lottery quizz titles and slots. Strengths - fast sessions, a clear betting/winning economy, high conversion from "light" games to the main showcase and a mature HTML5 implementation for web/mobile. Integration is standard: SSO launch, wallet collbacks (BET/WIN), JS bridge events, optional freespins and tournaments.

Who fits: Operators who require a "light" showcase with short rounds and a high event rate (instant/crash), as well as a neat conversion to slots and jackpots without overloading the frontend.

Portfolio and user experience

Main categories

Instant Win/Scratch: instant reveal, multiple tickets/cards, multipliers/modifier characters.
Crash/Arcade: rising odds/timers, "cash-out" in the risk window, multiplayer/quasi-multiplayer UX.
Lottery/quiz titles: fast draws/quiz rounds, number selections, simple paytable.
Slots (HTML5): 3 × 3/5 × 3/6 × N, lines/ways, respins, multipliers, buy-bonus (if allowed by the market).

UX/UI

Instant loading of the first screens (lazy-load assets), understandable CTA, clear paytable.
History of rounds, hints on features, training for crash/arcade (when to do cash-out).
L10n: multilingual/multicurrency, local number/date formats, RG messages.

Responsible play

Betting/session/time limits, risk alerts in crash games, geo/age blocking of prohibited content.

Technology and performance

Client: HTML5 (Canvas/WebGL), optimized sprites/audio, stable FPS, memory savings on mobile.
Delivery: CDN/edge caching, TTL controlled, fallback domains; fast FCP/TTI.
Network: TLS 1. 2 +, HTTP/2 +, latency to the nearest PoP <150-200 ms; stability when minimizing an application (mobile webview).
Crash/Arcade transport: light event channel (JS-bridge/WS) with impersonal "scoreboards "/boards.

Math, RTP and Limits

RTP pools: usually several profiles (for example, ~ 96 %/ ~ 94 %/ ~ 92%) at the build/catalog level for market/contract requirements.
Volatility: low (instant/scratch) to medium/high (crash/slots); the Volatility/Hit Rate display badge is recommended.
Limits: min/max rate, limits of auto-series (instant), buy-bonus is enabled/disabled by jurisdiction.
Currencies: accounting in minor units (integer accounting), correct rounding according to country norms.

Integration: high-level scheme

1. The player → the front of the operator → SSO/JWT (short TTL).
2. Operator/Aggregator API ↔ Gamevy API: creating a session, issuing 'launch _ url'.
3. Client (iFrame/new window) ↔ Game Server: game client + JS bridge (postMessage/SDK) and/or WS for crash/scoreboard.
4. Operator Wallet API: BET (auth-debit), WIN/PAYOUT (credit), rare adjustments/cancellations.
5. BI/Monitoring: analytics events, round reports, nightly/hourly reconciliation.

Environmental requirements

Security: IP-allowlist for S2S, request signing, key/secret rotation, strict CSP for iFrame domain.
Reliability: queues per player/session, retrays with exponential pause, deadlock by keys.
Compatibility: current Chrome/Edge/Safari/Firefox, iOS/Android WebView.

Create and start a session (pseudo-REST)

Request:


POST /api/v1/sessions
Authorization: Bearer <operator-key>
{
"player_id": "u_74219",
"currency": "EUR",
"locale": "ru-RU",
"game_id": "gamevy_<slug>",
"product": "instant    crash    slot",
"return_url": "https://operator. example. com/casino/return",
"limits": { "bet_min_minor": 50, "bet_max_minor": 200000 },
"flags": { "buy_bonus": false },
"tags": { "vip_level": 1, "aff_id": "AFF-214" }
}

Answer:


{
"session_id": "sess_fa21...",
"launch_url": "https://gv. example. com/launch? sess=sess_fa21...",
"expires_in": 3600
}

Client launch: via 'launch _ url' in iFrame/window; heartbeat/reauth - seamless extension; 'postMessage' for events.

Wallet API and idempotency

Transactional flows

BET (auth-debit): rate freeze/write-off → response'APPROVED/DECLINED '(+ balance/reason).
WIN/PAYOUT (credit): Credits the win/jackpot → returns the final balance.
ADJUST/REVOKE: force majeure adjustments (strict audit).

Delivery Guarantees

Header'X-Idempotency-Key '(TTL ≥ 24 h), deadlock on the operator side.
Per player/session queues → guaranteed transaction order.
Correlation on 'round _ id '/' bet _ id '/' session _ id'.

Example of payment:


POST /wallet/payouts
Idempotency-Key: 93ab-...
{
"player_id": "u_74219",
"round_id": "r_2025_11_02_16_58_21",
"amount_minor": 67500,
"currency": "EUR",
"reason": "round_win"
}

JS Bridge and Gaming Events

Client → operator: 'GAME _ INIT', 'BET', 'WIN', 'FEATURE _ TRIGGER', 'BONUS _ START/END', 'CASH _ OUT' (crash), 'ERROR'.
Transport: 'postMessage '/JS-SDK with ACK/NACK; strict verification of'origin' and signatures.
Purpose: analytics/CRM triggers, promo banners (free rounds/tournaments), local UI events.

Crash/arcade integration features

Round parameters: starting multiplier, coefficient growth, betting window and a separate cash-out window.
Events: 'ROUND _ TICK' (multiplier update), 'BETS _ CLOSED', 'CRASH', 'CASH _ OUT', 'ROUND _ RESULT'.
Reliability: auto-reconnect the client, resynchronize the current multiplier, protect against "double" cash-out through idempotency 'bet _ id'.
Anti-fraud: message throttling, limits on the frequency of bets/cashouts, ASN/VPN anomalies.

Free Rounds, Missions and Tournaments

Free Rounds

Issuance: through the provider API or synchronization with the operator's bonus engine.
Parameters: fix. bet/denom, number of rounds, expiration date, 'game _ id', campaign source.
Accounting: winnings in real/bonus-balance; vager - according to operator/market rules.

Missions/Events

Tasks for "X rounds "/" X wins "/" reach the multiplier N" (crash).
'MISSION _ PROGRESS '/' TOURNAMENT _ SCORE'events to analytic stream, anti-abuse filters.

Jackpots

Fixed/local/network layers (if any); separate collbeck 'JACKPOT _ PAYOUT' with idempotency.

Geo-configuration and compliance

Geo directory: inclusion/exclusion of titles, RTP profiles, disabling buy-bonus/risk games, age/regional restrictions.
RG: self-exclusion, deposit/rate/time limits, local banners/cookies.
Data: PII minimization, 'player _ id' tokenization, log retention and export at the request of regulators.
Certification: use of certified builds/versions for target markets.

Monitoring, Reporting, SLA

Key Metrics

Тех: uptime API/Launch/CDN; p95 purse collbacks; download speed; WS errors/losses (crash).
Product: 'Launch → First Bet/Reveal/Cash-Out', average check, hold, ROI promo/freespins, mission achievement.
Finance: share of retrays/deduplications, anomalies in amounts, discrepancies in nightly reconciliations.

Reports/Reconciliation

Hourly/daily offloads (CSV/JSON/S3) by round/transaction.
Reconciliation by'round _ id/bet _ id/session _ id'and amounts in minor-units; auto-alerts to duplicates/omissions.

SLO/SLA (landmarks)

API uptime ≥ 99. 95%, assets/CDN ≥ 99. 9%; p95 collbecs <500 ms (within the region).
For crash: reconnect ≤ 3-5 with p95; correct resynchronization of the multiplier.

Security

Transport: TLS 1. 2+, HSTS; Strict CSP for iFrame domain.
Access: JWT/OAuth2 for sessions, IP-allowlist and S2S signature, rotation of secrets.
Data: prohibition of open PII in logs, hash/tokenization of identifiers, encryption at rest/backup.
Anti-fraud: betting/cashout frequency anomalies, multiple sessions, VPN/ASN patterns; quotas/throttling.

Scalability and fault tolerance

Edge cache: manifests/assets/localizations - managed by TTL, manual disability on releases.
Rate-limits: per player/session/API endpoint; protection against "storms" of events.

Graceful degradation: simplifying assets/effects, reducing the frequency of events, banner "technical work."

Failover: backup launch/CDN domains, re-issue token without loss of context.

Checklists

For development

Generation/validation of SSO tokens (short TTL, clock-skew).
Wallet API: idempotent debit/credit, signature, queues, DLQ.
JS bridge (postMessage/SDK): events, ACK/NACK, error handling.
Crash: WS client, auto-reconnect, multiplier synchronization, double cash-out protection.
Free Rounds API: Issue/Activate/Redeem, Vager Accounting.

To start

Geo-directory, RTP profiles, disabling prohibited features (buy-bonus/risk game).
SLO monitoring (API/CDN/Wallet/WS) + alerts.
Nightly reconciliation and discrepancy alerts.
RG/cookie banners, local requirements.
Incident plan and status pages.
