What's in this feed

We track six change types: stated RTP changed, native RTP variants updated, slot added or removed from a provider's catalog, new provider integrated, and provider coverage status reclassified (complete / partial / exhausted_public).

A new entry appears here only when the weekly cron detects a meaningful diff: ≥0.5% of slots changed RTP, any new variant detected, ≥25 net new slots, ≥50 metadata improvements, or any provider/coverage change. Smaller drift is logged in the run report but not committed to the public feed — keeps the changelog signal-rich.

Programmatic consumers: hit /api/rtp/history for the JSON feed (filter by type, slot, provider, or since). Cron schedule: every Monday 06:00 UTC.

How this RTP tracker works

Weekly monitored snapshots

Every Monday at 06:00 UTC we re-scan all 15 providers, compare the new dataset to the previous frozen version, and append only meaningful changes to the public feed.

Signal-rich diffs, not noise

Minor page drift stays in internal run logs. This public changelog focuses on events editors and players can actually cite: RTP changes, new variants, new slots, removed slots, and coverage updates.

Source-backed and reviewable

Each release is tied to provider pages, timestamps, and versioned registry data. That makes the feed useful not just for browsing, but for journalism, audits, and historical verification.

Why RTP changes matter

For players and casino reviewers

A slot can keep the same name while its published RTP or available variants change over time. Tracking those moves helps explain why an older review, bonus guide, or casino comparison may no longer match the latest provider data.

For researchers and affiliate editors

A structured changelog creates a citation trail. Instead of saying a provider "sometimes changes RTP", you can point to dated entries, provider clusters, and annual archives built from the same registry.

What RTP change tracking means for slot reviewers

RTP is not a static spec sheet number. A provider can roll out a new game build, swap the default variant a casino is allowed to deploy, or quietly retire a slot from the public catalog. Each of those moves shows up here as a dated entry in the Slot RTP Registry, with the source URL and snapshot hash that captured it.

The feed is rebuilt from a frozen snapshot every Monday at 06:00 UTC. The diff engine flags meaningful drift only — half-percent RTP shifts, brand-new variant tiers, twenty-five or more net new slots from a provider, or a coverage reclassification. The exact thresholds and confidence model live in the methodology. Older runs are available in the 2026 archive.

If you write slot reviews, build a comparison tool, or run a player community, this feed is meant to be cited. It works alongside the best RTP rankings and the biggest variant ranges so a single dated entry tells the full story: what changed, when we saw it, and which provider page proves it.

FAQ

How often does the changelog update?▸
The feed updates after the weekly cron run every Monday at 06:00 UTC. If a provider page changes in a meaningful way, the new diff appears here automatically.
What counts as a meaningful RTP change?▸
We publish entries for stated RTP changes, native RTP variant updates, slot additions or removals, new provider integrations, and provider coverage reclassifications. Small cosmetic drift does not create public feed entries.
Why is this page paginated instead of one endless feed?▸
Pagination keeps the changelog usable as the archive grows into hundreds of entries. It also preserves crawlable URLs for older pages instead of hiding history behind client-only infinite scroll.
Can I filter to RTP-only updates?▸
Yes. Use the filter buttons at the top of the page to switch between all changes, RTP-only changes, new slots, and removed slots. Provider-specific archives also have dedicated URLs.
Is there a machine-readable version of this feed?▸
Yes. The same data powers /api/rtp/history, which supports filters like type, provider, since, until, limit, and offset.
Why link out to provider-specific changelog pages?▸
Provider pages reduce noise for readers who only care about one catalog, such as Pragmatic Play or NetEnt. They also build a cleaner archive structure than creating thousands of thin per-slot history pages.
Why does the RTP change for a slot?▸
Providers ship multiple math models for the same game and let the operator pick which version to deploy. When a provider updates the default version, retires an older build, or publishes a new RTP tier, the headline number on their page changes. We pick that up on the next weekly run. See the methodology for how we read provider pages.
How often do providers actually change RTP?▸
It varies. A few providers push variant updates quarterly when they renegotiate operator contracts. Most leave a slot's published RTP untouched for years. Looking at the per-provider columns on this page shows which catalogs see the most movement and which stay flat.
Can a casino offer a different RTP version of the same slot?▸
Yes, this is the whole reason native RTP variants exist. The same slot at one casino may run a 96% build while another casino runs a 91% build of the exact same game. The provider publishes the menu of available variants and the operator chooses. Casinos under UK regulation must disclose the live variant on the rules page. Most do not unless asked.
How do you verify the RTP history is accurate?▸
Every observation is content-addressed with a sha256 of the full HTML snapshot at fetch time. We keep the snapshot for as long as the registry exists, so any past RTP claim can be replayed against the page we actually read. The full provenance chain is documented in methodology.
