Sites with certified slots from providers

What counts as a "certified slot"

Original build from the studio/platform (without modifications to the payment tables and mechanics).
RNG/game certification by an independent laboratory (eCOGRA, iTech Labs, GLI, BMM, etc.).
Public verification: indication of RTP/version in the game and on the provider's page, matching rules.
Download via official platform (RGS/aggregator) rather than via random third-party domain/CDN.

Where to look for sites with guaranteed "original" slots

1. Licensed casinos (UKGC/MGA/Isle of Man/Gibraltar/Alderney/current Curaçao with CGA): They have direct integrations or certified aggregators.
2. Brands celebrating providers in the lobby and T&C (Play 'n GO, Pragmatic Play, NetEnt/Red Tiger, Games Global/BTG, Nolimit City, Relax, ELK, Yggdrasil, Blueprint, IGT, Playtech, Greentube, etc.).
3. Platforms with transparent "Game Rules": RTP, versions, bans (Bonus Buy/bonus bets), games contribution to the vager are indicated.

7 signs you have the original certified slot

1. RTP and the version in Info/Paytable games match the values ​ ​ on the provider's website.
2. Download domains belong to the official provider/aggregator platform (checked in DevTools → Network).
3. The paytable and triggers are identical to the demo at the vendor (coefficients, conditions of frispins/respins).
4. Mention of laboratory and/or RNG certification references in casino regulations.
5. Stable UI/UX: the same localization, fonts, effects and "flow" events, as in the demo from the vendor.
6. Multi-version RTP (for example, 96/94/92) are correctly reflected in Info; Ante/Bonus Buy shows a modified RTP.
7. Matching region parameters: the game version is available in your GEO (without gray mirrors and proxy redirects).

Algorithm for checking the site in 15 minutes

1) License and legal entity (2-3 min)

Find the regulator and the license number on the website → reconciliation in the public register.
Does the brand/domain/legal entity match the string in the registry.

2) Providers and lobbies (3-4 min)

The lobby has recognizable studios and a label for each provider.
In "Game Rules" RTP/versions, the contribution of games to the vager, prohibitions are indicated.

3) Slot test (5-6 min)

Open 2-3 games: compare RTP/Paytable with the provider's pages.
In DevTools → Network, check where requests go (official platform/aggregator).
Catch the mini-feature/respin: the logic and multipliers coincide with the demo video/description from the vendor.

4) Certification and T&C (3-4 min)

Is there a mention of eCOGRA/iTech/GLI/BMM (or equivalent) in the site rules/" Fairness/RNG "section.
The bonus rules have max bet, cap, deadlines, the contribution of games - without "gray" reservations.

How to distinguish "clone "/illegal assembly

There is no RTP in the game, and in T&C there is a vague wording.
Different coefficients in Paytable than the provider; "trimmed" multipliers/jackpot.
Loading from an incomprehensible CDN/domain that is not in the provider/aggregator ecosystem.
Slow/ragged animations, mismatched fonts/localization.
Audit "seals" without clickable links to the certification registry/page.

Important nuances of certification

The RNG certificate is issued to the engine/platform and/or specific games/versions; bundles are re-tested at large updates.
Jurisdictions allow different RTP pools (for example, 96/94/92). See the actual RTP within the game.
Bonus Buy/Ante change the math: some games have a separate RTP version.
Progressives: RTP portion "sits" in jackpot; without accumulation, the base feels "tougher."
