Microgaming - Overview and Integration

2) Portfolio and content

2. 1 Slots (core)

Subjects: classics/fruits, adventures, mythology, branded-series.
Mechanics: Free Spins/Respins, Wild/Expanding Wild, Multiplier, Rolling/Avalanche, Ways/Megaways (in separate titles), sometimes Feature Buy (depending on market/game).
RTP profiles: several options (e.g. 96. x/94. x/92. x), selection by jurisdiction.
Volatility: low to very high; game cards usually have a tag.

2. 2 Progressive Jackpots

Mega Moolah network pools (multi-level: mini/minor/major/mega), individual local progressives.
Require correct integration of pool, currencies and reporting (see § 8, § 9).

2. 3 RNG tabletops/variants

Roulette/blackjack/poker options - depend on connection package and market.

2. 4 Examples of top titles

Mega Moolah (series) - progressive jackpots, high traffic peaks.
Thunderstruck II, Immortal Romance, 9 Masks of Fire, Book theme - sustained hits/re-activations.

3) Jurisdictions and Restrictions

They differ: RTP profiles, betting/winning limits, Autoplay/Quick Spin/Feature Buy statuses, mandatory Responsible Gaming texts/banners.
Not all jackpots and pool currencies are available in every market.
Regulators require cut-off reporting, round-level log storage, and, if necessary, on-demand exports.

• `region → rtp_profile, features_allowed, bet_limits, jackpot_pool, texts_required`.

4) Integration architecture

4. 1 Wallets

Seamless (transfer-less): operator's balance; calls to '/authorize ', '/bet', '/win ', '/rollback'; idempotency is mandatory.
Transfer Wallet: pre-transfer of funds to the RGS side; final synchronization at session close.

4. 2 Interfaces (sketch)

4. 3 Idempotency/order

Unique 'transaction _ id' (UUID/ULID) for each 'bet '/' win'; repeat with the same ID must return the same result (exactly-once in meaning).
Mandatory'round _ id '; store the mapping'provider _ game _ id → internal_game_id'.

4. 4 Timeouts/Retreats

Client timeouts 2-3 s, exponential backoff, replay queue, response deduplication.

4. 5 Localization/devices

Multilingual UI, correct currencies/formats, light assets and mobile-first optimization.

5) Event diagram and analytics

5. 1 Mini Event Diagram (JSON)

json
{
"event_id": "01J...MM",
"event_time": "2025-11-02T12:31:05Z",
"type": "bet    win    bonus    jackpot    session_start    session_end    disconnect    reconnect",
"user": {"id":"u123","tenant":"op1","country":"CA"},
"game": {"id":"mg_immortal_romance","rgs":"microgaming","category":"slot"},
"session": {"id":"s456","device":"android","ip":"..."},
"wager": {"amount":1.00,"currency":"EUR","round_id":"r789"},
"payout": {"amount":12.40,"jackpot":false},
"meta": {"rtp_profile":"96","jurisdiction":"MGA"}
}

5. 2 Key metrics

GGR/NGR by game/channel/market; Hit Rate, Spin Frequency, Bonus Entry Rate.
Jackpot Contribution/Win (by pool/currency).
RGS quality: p95/p99 API, error-rate, lag webhooks, retry queue size.
Player/session: ARPPU/ARPU, avg session length, churn signals, complaints/1k rounds.

5. 3 Anti-fraud/anti-arbitrage

Bonus carousels, abnormal win-profiles, multi-account/device, geo-offsets.
Reactions: pause promo/play by segment, betting limits, manual check.

6) RTP, volatility and exposure

Store'rtp _ profile'per market; block Autoplay/Feature Buy where prohibited.
Exposure control: 'max _ potential _ payout' by round/game; for the jackpot - separate limits and insurance rules.
For high-volatility slots, configure limits/guardrails for the VIP segment.

7) Promo and showcase

Free Spins on hits (e.g. Immortal Romance) for onboarding/re-activation.
Leaderboards/win-multiplier/win-total tournaments.

Showcase: "New," "Hits Microgaming," "Progressive Jackpots (Mega Moolah)," "High Volatility," "Classic."

Tags mechanics: Progressive/Jackpot, Avalanche, Multiplier, Classic, Book.

Assets: 1:1 icons, 16: 9/4: 3 posters (webp), short preview videos, localized titles/descriptions.

8) Jackpots (Mega Moolah et al.)

8. 1 Pool parameters

'seed ',' contribution _ pct ',' tiers' (mini/minor/major/mega), pool currency, list of participating games.
Requires separate webhook 'and jackpot win and independent payout ledger.

8. 2 Currencies/Markets

Not all currencies/countries are connected to a specific pool; failure - deterministic and understandable to the user.

8. 3 UI/UX

Widgets of the amount/history of winnings, localization/grades/currency; RG banners according to the market.

8. 4 Exposure and risk

Monitor 'max _ potential _ payout' and hit frequency; with a surge in exposure - auto-reduction of rate limits (if permissible by policy).

9) Reporting and reconciliation

Round-level logs (bets/payouts/bonuses/jackpot/statuses).
Daily Game Report by Games/Currencies/Markets; cut-off according to the provider's server time (store TZ/offset).
Reconciliation: sum of events at the operator vs summary reports; permissible delta - on unclosed rounds.

10) Observability and SLO integration

API: p95/p99 для `/authorize`, `/bet`, `/win`; error-rate, percentage of duplicate transactions.
Events: lag webhooks, retry queue size, 'rollback/void' share.
Product: crashes/1000 rounds (client), disconnect-rate.
Billing: discrepancy of reports <target threshold, percentage closed to cut-off.

SLO (sketch)

yaml slo:
api:
bet_p95_ms: 250 win_p95_ms: 250 error_rate_pct: <=0.3 events:
webhook_lag_p95_s: <=3 duplicate_txn_pct: <=0.1 billing:
report_delta_pct: <=0.2 closed_by_cutoff_pct: >=99.7

11) Safety and compliance

mTLS + HMAC signatures, allowlist IP, short-lived tokens.
PII minimization and tokenization of 'user _ id'; RLS/CLS by tenant/region.
Responsible Gaming: Reality Check, limits/self-exclusion; correct texts and fonts by market.
Jurisdictional flags in the startup config: autoplay/quick spin/feature buy, bid/session limits, RTP disclosure.

12) Test plan and QA

12. 1 Staging checklist

• '/authorize '/close the session; languages/currencies/formats.
• '/bet '/'/win 'are idempotent; repeat with same'traction _ id '- old response.
• Free Spins/Bonus accrual → expense → report.
• Jackpot: win test, ledger entries, cut-off report.
• Jurisdictions: Autoplay/Feature Buy ban, RTP profile, bid/session limits.
• Showcase/assets: localization, tags mechanics, shelf "Progressive."

12. 2 Negative scenarios

Duplicate 'transaction _ id' → 200 with past result.
Timeout '/win '→ secure retry without double payout.
Currency/market without jackpot pool → correct rejection.
Disconnect/Resume → the integrity of the state and round.

13) Frequent errors and anti-patterns

Single RTP to all markets; display of prohibited features → compliance risks.

14) Configuration templates

14. 1 Game/Market

yaml game_config:
game_id: "mg_immortal_romance"
markets:
- region: "MGA"
rtp: "96.0"
features: {autoplay: true, feature_buy: true}
bet_limits: {min: 0.20, max: 100}
- region: "UKGC"
rtp: "94.0"
features: {autoplay: false, feature_buy: false}
bet_limits: {min: 0.10, max: 10}

14. 2 Jackpot Pool (Mega Moolah, example)

yaml jackpot_pool:
name: "mega_moolah_eur"
currency: "EUR"
seed: 1000000 contribution_pct: 2.0 tiers: [mini, minor, major, mega]
games: ["mg_mega_moolah","mg_fortune_factory_mm","mg_temples_tombs_mm"]

14. 3 Idempotence policy

yaml idempotency:
key: "transaction_id"
storage: "redis+db"
ttl: "30d"
behavior: "return_last_result"

14. 4 Diagram of events (minimum)

yaml events:
keys: [event_id, event_time, type, user.id, game.id, session.id, wager.round_id]
bet:  [amount, currency, ext_ref]
win:  [amount, jackpot, ext_ref]
tech: [client, device, latency_ms]

15) Implementation Roadmap

1. Inventory & Markets: list of Microgaming games, RTP profiles, feature flags, limits; a map of jackpot and currency pools.
2. API & Wallet: choice of wallet model, idempotency, retrai, webhooks.
3. Events & Reports: event schema, round-level logs, cut-off and TZ.
4. Compliance: jurisdictional configs, RG requirements, texts/banners.
5. Promo: freespins/leaderboards/missions, window integration and CRM.
6. Observability: SLO panels (API/events/billing), alerts, replays.
7. Go-Live: canary traffic, KPI comparison (GGR, hit rate, complaints), first week post-mortem.

16) The bottom line

Microgaming combines "long-playing" hits and powerful progressive jackpots that consistently convert traffic. Successful integration is based on idempotent billing, correct RTP/features by jurisdiction, transparent reporting with cut-off, jackpot exposure management and SLO observability. With a thoughtful showcase and promo, Microgaming's portfolio provides a predictable contribution to GGR/LTV at a controlled risk and cost of service.
