Swintt - Overview and Integration

Overview

Swintt is an HTML5 slot provider with two key areas: the "classic" line with laconic mathematics and "modern" video slots with advanced mechanics (multipliers, collections, respin/hold-and-win). Clients are light, quickly loaded into mobile WebViews. Integration is standard: SSO → launch-URL, wallet collections BET/WIN/JACKPOT, JS bridge events for analytics and promo.

Who fits: operators/aggregators who need recognizable classic themes + regular releases of video slots with predictable integration and moderate TCO.

Portfolio and user experience

Content and Mechanics

Video slots: 5 × 3/6 × N; lines/ways; cascades (on part of titles); xN multipliers, expanding/stacked/walking wilds; respins/hold-and-win; character upgrades.
Classic slots: 3 × 3/5 × 3 "fruits/sevens/BAR" with modern mathematics and accelerated gamelup.
Bonus modes: freespins, pick-bonus, "ladders" of multipliers, sticky mechanics.
Buy Feature/Bonus Buy: optional (depending on title and jurisdiction).
Jackpots: fixed/local/network - by connection configuration.

UX/UI

Fast FCP/TTI, compact assets, stable FPS on mobile.
Clear paytable, round history, Volatility/Hit Rate display badges.
L10n: multilingualism and multicurrency, local number/date formats, RG notifications.

Technology and performance

Client: HTML5 (Canvas/WebGL), lazy-load, sprite/audio compression, critical resource preload.
Delivery: CDN/edge caching, TTL managed, backup launch/CDN domains (failover).
Network: TLS 1. 2+, HTTP/2+; target latency to nearest PoP <150-200 ms.
Mobile: correct resume after folding, CPU/battery savings, resistance to network loss.

Math, RTP and Limits

RTP pools: usually several profiles (landmarks ≈96 %/ ≈94 %/ ≈92%); selection at the build/catalog level for the market and contract.
Volatility: from low/medium (classic) to high (hold-and-win/multipliers).
Limits: min/max-rate, auto-backs, session timeouts, day/hour RG limits.
Currencies: calculation in minor units (integer) with correct rounding according to local norms.

Integration model (high-level)

1. The player → the front of the operator → SSO/JWT (short TTL).
2. Operator/Aggregator API ↔ Swintt API: create session, get 'launch _ url'.
3. Client (iFrame/new window) ↔ Game Server: game client + JS bridge (postMessage/SDK).
4. Wallet operator API: BET (auth-debit), WIN/PAYOUT (credit), JACKPOT_PAYOUT, rare adjustments.
5. BI/Reports: analytical events, round/transaction uploads, reconciliation.

Environmental requirements

Security: IP-allowlist S2S, request/response signing, key/secret rotation, strict CSP for iFrame domains.
Reliability: retrai with exponential pause, per player/session queues, key deadlock, sticky routing.
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_57021",
"currency": "EUR",
"locale": "ru-RU",
"game_id": "swintt_<slug>",
"return_url": "https://operator. example. com/casino/return",
"limits": { "bet_min_minor": 100, "bet_max_minor": 400000 },
"flags": { "buy_feature": false, "autoplay": true },
"tags": { "vip_level": 1, "aff_id": "AFF-642" }
}

Answer:


{
"session_id": "sess_ae73...",
"launch_url": "https://swintt. example/launch? sess=sess_ae73...",
"expires_in": 3600
}

Client launch: via 'launch _ url' in iFrame/window; heartbeat/reauth supported; events across the JS bridge (ACK/NACK).

Wallet API and idempotency

Main flows

BET (auth-debit): rate freeze/write-off → response'APPROVED/DECLINED '(balance/reason).
WIN/PAYOUT (credit): Credits winnings/jackpots → returns final balance.
ADJUST/REVOKE: exceptional adjustments (full audit trail).

Delivery Guarantees

Header'X-Idempotency-Key '(TTL ≥ 24 hours) and deadlock on the operator side.
Per player/session queues → guaranteed order.
Correlation by 'round _ id '/' bet _ id '/' session _ id'; DLQ for collisions/replicates.

Example of payment:


POST /wallet/payouts
Idempotency-Key: 9d1c-...
{
"player_id": "u_57021",
"round_id": "r_2025_11_02_19_45_33",
"amount_minor": 158000,
"currency": "EUR",
"reason": "round_win"
}

JS Bridge and Gaming Events

Client events → to the operator: 'GAME _ INIT', 'SPIN/BET', 'WIN', 'FEATURE _ TRIGGER', 'BONUS _ START/END', 'JACKPOT _ HIT', 'ERROR'.
Transport: 'postMessage '/SDK, ACK/NACK acknowledgements, strict' origin 'validation and nonce/signatures.
Application: analytics, CRM triggers, banner personalization and campaign connection.

Promo: freespins, missions, tournaments, jackpots

Free Rounds / Free Spins

Issuance via Provider/Promo API or synchronization with bonus engine.
Parameters: fix. bet/denom, number of spins, expiration date, 'game _ id'.
Accounting: winnings in real/bonus-balance; operator/market rules wager.

Missions/Events

"Play N spins," "win ≥ X ×," "activate feature M times" - progress through analytical events.

Tournaments/leaderboards

By the amount of winnings, max-multiplier, the number of spins; 'TOURNAMENT _ SCORE'events to dimension.

Jackpots/Prize-drops

Multi-level pools (mini/major/mega), mystery/prize-drops; 'seed/cap', multi-currency restrictions; single 'JACKPOT _ PAYOUT'.

Geo-configuration and compliance

Geo directory: including/excluding titles, choosing an RTP profile, disabling Buy Feature/risk games, age/regional restrictions.
Responsible game: self - exclusion/time auty/limity of deposits/rates/time, local RG banners and cookie-consent.
Data/PII: minimization and pseudonymization of identifiers; log storage periods; export according to regulatory requirements.
Certification: use of certified builds/versions under target jurisdictions.

Monitoring, Reporting and SLAs

Key Metrics

Those: uptime API/Launch/CDN, p95 wallet collabs, asset download speed, JS bridge error rate.
Product: 'Launch → First Spin', 'Spin → Bonus', ARP (B) U, hold, ROI campaigns (freespins/missions/tournaments/drops).
Finance: share of retrays/deduplications, anomalies in amounts, nightly discrepancies.

Export/Reconciliation

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

SLO/SLA Benchmarks

API uptime ≥ 99. 95%, CDN assets ≥ 99. 9%; p95 collbecs <500 ms (intraregional).
MTTR - according to the incident plan; separate SLOs for prime time/mass campaigns.

Security

Transport: TLS 1. 2+, HSTS; strict CSP for iFrame domains.
Access: JWT/OAuth2 (client), IP-allowlist/signature/mTLS (S2S) if necessary, rotation of secrets.
Data: prohibition of open PII in the logs; tokenization/hash 'player _ id'; encryption at rest/backup at the operator.
Anti-fraud: spin/bet rate anomalies, multiple sessions, suspicious ASN/VPN; quotas/throttling/block lists.

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 losing context.

Checklists

For development

Generation/validation of SSO tokens (short TTL, clock-skew protection).
Wallet API: idempotent debit/credit, signature, queues, DLQ.
JS bridge/SDK: events, ACK/NACK, secure 'origin'.
Promo API: freespins/tournaments/missions/drops; vager accounting.
Export: CSV/JSON/S3; completeness of fields (minor units, round/bet/session).

To start

Geo-directory, RTP profiles, disabling prohibited features.
SLO monitoring (API/CDN/Wallet/JS) + alerts.
Nightly reconciliation + duplicate/skip alerts.
RG/cookie banners, local requirements.
Incident plan and status page.

Running in iFrame? Yes, through 'launch _ url' with consistent CSP/' X-Frame-Options'.
Is Buy Feature available? By title/market; is configured.
Are there network jackpots? By configuration; payments - individual 'JACKPOT _ PAYOUT'.
