The strongest public evidence is a specific publisher product or permission pathway—not merely a prominent studio name. The following is a qualification matrix, not an endorsement list.
| Supplier or platform | What the reviewed public evidence establishes | What remains unresolved for a US-facing publisher | Procurement position |
|---|---|---|---|
| First Look Games | Free publisher access and Demo Game Server access for verified affiliates. Its publisher EULA restricts use to promotional materials and game reviews and requires observance of studio-specific restricted markets. | Eligible studios and titles for the intended US audience; signed scope; technical acceptance. | Investigate for editorial demos, subject to restrictions. (firstlookgames.com) |
| Playin | An affiliate page supplies demo iframe examples, external-link options, JSON game information and studio assets. | Exact territorial, commercial, support and downstream-use conditions for the buyer. | An explicit publishing pathway worth qualifying, not nationwide permission. (playin.com) |
| Pragmatic Play | Its official company page expressly describes relationships with affiliate partners. | A public, buyer-specific demo licence and US distribution scope were not established. | Direct outreach lead; do not assume free or unrestricted embedding. (pragmaticplay.com) |
| Slots Launch | Publisher subscriptions, WordPress integration, API access and direct embeds are advertised. | Sufficient upstream rights evidence, exact US coverage and negotiated continuity protections. | Publisher-oriented paid option; evaluate the migration requirement below. (slotslaunch.com) |
| SOFTSWISS Game Aggregator | Its official FAQ says operators need their own licensed online casino to use the product. | Whether a separate demo-only publisher arrangement exists. | Do not shortlist as an ordinary demo subscription without written exception or a separate offer. (softswiss.com) |
| EveryMatrix / SlotMatrix | Official material documents casino content aggregation for betPARX, including a US operator relationship. | Independent publisher eligibility, demo-only economics and downstream website rights. | Conditional enterprise lead, not proof of a publisher demo product. (everymatrix.com) |
| MarketJS | Fixed-fee licences can deliver compiled files for self-hosting; subscriptions deliver hosted links. Standard licensing is for one domain, with bespoke multi-domain arrangements available. | Suitability of individual games, usage scope, maintenance and any custom terms. | An original-browser-game alternative, not automatically a substitute for a named casino demo. (marketjs.com) |
| SlotCatalog | Public material offers discussions about data partnerships, while other documents impose important reuse and territorial restrictions. | The controlling written agreement for US-facing affiliate publication and any playable-content rights. | Hold for contractual clarification; see the conflicting evidence below. (slotcatalog.com) |
What are the most important dated procurement alerts?
First Look Games: distinguish demo access from API availability
Do not plan an API-dependent launch on the assumption that the advertised API is currently available. The dedicated API page reviewed for this report states that the API is temporarily unavailable during upgrades. That is different from the Demo Game Server workflow described elsewhere. Obtain a written availability statement and working credentials before committing to an automated implementation. (firstlookgames.com)
The Demo Game Server guidance dated 20 August 2026 describes spreadsheet export and registered-domain embedding. It also says demos depend on studio uploads, not every game has one, and dashboard sessions represent account-wide page loads rather than per-game plays. A catalogue listing or account session counter therefore should not be treated as proof of game coverage or successful gameplay. (firstlookgames.com)
Slots Launch: the published signing cutoff is 15 November 2026
As of 28 October 2026, the documented migration date is still in the future. Slots Launch’s documentation sets 15 November 2026 as the cutoff for moving iframe embeds and API calls to signed requests, unless account-specific legacy mode applies. Existing customers should confirm the exact cutover time, plugin support and any exception in writing. (docs.slotslaunch.com)
The embed guide warns against allowing cached pages to serve expired signed URLs. Its recommended patterns generate fresh signatures server-side; the API secret must not be exposed in front-end code. Include cached-page expiry, credential rotation and launch-button behaviour in acceptance testing. (docs.slotslaunch.com)
SlotCatalog: public documents do not provide a clean permission answer
Do not resolve contradictory public wording in the buyer’s favour. A publicly accessible commercial PDF says its data should not be published on affiliate resources. The company’s About page nevertheless invites affiliates to discuss data partnerships. These statements support asking for a specific agreement, not assuming either universal permission or a universal ban. (slotcatalog.com)
The website terms dated 15 October 2026 require written consent for commercial reuse and say separate B2B agreements govern the services they cover. Their restricted-country schedule also names the United States and its territories. Treat this as a procurement hold for a US-facing brief until the supplier explains the applicable territorial and publication scope in a controlling written agreement. This is not a conclusion about the legality of every SlotCatalog business relationship. (slotcatalog.com)
