How We Verify Game Facts

Slottomat lists facts for every slot in our catalog — return to player (RTP), volatility, maximum win, paylines, provider, and theme. This page explains exactly where those facts come from, how we decide which source wins when they disagree, how confident we are in each one, and how we fix mistakes.

This is the technical companion to our Editorial Policy, which covers how our slot pages are written and presented. This page covers the layer underneath that: the data record itself.

What we verify

For each game, these are the facts we check and display:

• RTP — the provider’s stated theoretical return-to-player percentage.
• Volatility — how a game’s outcomes vary (low, medium, or high), as classified by the provider.
• Maximum win — the theoretical top payout, expressed as a multiplier of the stake (for example, “up to 5,000x”).
• Paylines / ways to win — the game’s win-line or ways count.
• Provider — the studio that built the game (for example, Pragmatic Play, NetEnt, Play’n GO).
• Theme — the game’s subject (Egyptian, fishing, ocean, fruit, and so on).
• Playable demo — whether the free, no-money demo actually loads.

Our source hierarchy (database-first)

We do not invent figures, and we do not copy them from other listing sites. Every fact follows the same order of authority:

1. Our first-party game database is the system of record. Each game is a structured record in a database we maintain ourselves, and each fact lives in its own field. Every value shown on a game page is read from that field — not typed by hand into the page, and not pulled from a competitor.
2. The game provider’s official information is authoritative. When we create or update a record, the provider’s own published information — game rules, official spec sheets, and provider pages — is the source we trust above all others. If a provider and a third party disagree, the provider wins.
3. Secondary sources are flagged low-confidence. Where a fact can only be found from a secondary source, we mark that field as lower confidence so it can be re-checked, and we would rather leave it blank than publish a guess.

A field left blank is deliberate. If we cannot confirm a value from a trustworthy source, we leave it empty instead of estimating. An empty RTP field means “not confirmed,” not “zero.”

How we handle conflicting numbers

Slot facts can legitimately differ between sources — providers ship multiple RTP versions of the same game, and older third-party listings go stale. When sources conflict, we resolve it at the record level:

• The provider’s official figure takes precedence over any third-party number.
• Where a game has multiple published RTP versions, we record the provider’s stated theoretical figure for the version we list, and we don’t present one configuration as if it were universal.
• When we cannot resolve a conflict confidently, we hold the value back rather than pick one and present false certainty.

About RTP specifically

RTP is a long-run theoretical figure published by the game’s provider. It describes how a game is designed to behave over a very large number of spins — it is not a prediction of any individual session. To be clear about what our RTP figure is and isn’t:

• It is the provider’s stated/theoretical RTP, recorded in our database from the provider source as described above.
• It is not an independently re-measured figure. We do not run our own millions-of-spins simulations to derive a separate number; we record and source the provider’s published figure honestly.
• Because providers can release multiple RTP versions of a game, the published figure is the design target for that version, not a guarantee for any single play. Our games are free demos, so this never involves money.

Demo availability checks

A fact about a game is only useful if you can actually try the game. Every game in our catalog is meant to have a working free demo that loads with no download, no registration, and no real money.

• We check that each game’s demo loads.
• Games whose demo does not load are flagged and hidden or removed so you don’t land on a dead page.
• We monitor demo availability continuously and re-check failures, so the playable set stays current.

Updates and re-checks

Game data is not static — providers patch games, adjust RTP versions, and release new titles.

• When a provider updates a game, we update our record from the provider source.
• Facts flagged lower-confidence are queued for re-checking against the provider’s official information.
• We re-check facts continuously rather than on a fixed calendar, so corrections land as soon as we confirm them rather than waiting for a scheduled pass.

Found something wrong? Tell us.

We want our facts to be right, and we’d rather hear about an error than leave it live.

• If you spot an RTP, max-win, payline, provider, or any other detail that looks wrong, report it through our Contact page.
• We re-check the flagged fact against the provider’s official source and correct the record if it’s wrong.

What we don’t claim

In the interest of being straight with you:

• We report the provider’s theoretical RTP, not an independently audited or re-measured one.
• We do not predict winnings, and nothing on this site is a real-money product.
• Casino offers shown on the site are clearly-disclosed advertising from partners and do not influence our game facts.
• We focus on accurate game mechanics, features, and specs. We do not publish betting systems or strategies — slot outcomes are random, and these are free demos with no real money at stake.

Common questions

Is the RTP independently tested?

No. We publish the provider’s stated theoretical RTP, sourced from the provider’s official information. We do not run our own simulations to re-measure it, and we don’t claim to.

Why is an RTP field sometimes blank?

Because we couldn’t confirm the value from a trustworthy source. A blank field means “not confirmed” — we leave it empty rather than publish a guess.

How do I report a wrong fact?

Use our Contact page. We’ll re-check the flagged detail against the provider’s official source and correct our record if it’s wrong.
