How does Slottomat verify RTP data for slot reviews?

Slottomat records each game's return-to-player (RTP) percentage as a structured field in our first-party game database, and the figure shown on a game page is read directly from that field. When we create or update a record, the source we trust above all others is the game provider's own official information — published game rules and provider spec pages. If a provider's figure and a third-party listing disagree, the provider's figure wins, and any value we can only find from a secondary source is flagged as lower-confidence so it can be re-checked. The RTP we show is the provider's stated, long-run theoretical figure. It is not a number we have independently re-measured — we do not run our own millions-of-spins simulations to derive a separate value. RTP describes how a game is designed to behave over a very large number of spins; it is not a prediction of any single session. If we cannot confirm an RTP from a trustworthy source, we leave the field blank rather than guess, so an empty RTP means "not confirmed," not "zero." Because all play on Slottomat is a free demo with play-money credits, no RTP figure ever involves real money.

How does Slottomat decide which game facts to display?

Slottomat does not score or rate games on a points system — there is no 1-to-10 scale and no weighted rating. Each game is a structured record in our first-party database, and we display the same set of objective facts for every title: RTP, volatility (low, medium, or high, as classified by the provider), maximum win expressed as a multiplier of the stake, paylines or ways to win, the provider that built the game, and the theme. Each of those facts lives in its own database field and is sourced from the game provider's official information, with the provider's figure treated as authoritative when sources disagree. We do not rank games against each other or assign a quality grade. Where a fact cannot be confirmed from a trustworthy source, we leave that field blank instead of estimating it. We also check that each game's free demo actually loads; games whose demo does not load are flagged and hidden or removed so you don't land on a dead page.

Does any game provider pay to influence the facts shown on Slottomat?

No. The facts shown for each game — RTP, volatility, maximum win, paylines, provider, and theme — are sourced from the game provider's official information and stored in our first-party database. No studio can pay to change a figure, and the same sourcing rules apply to every game regardless of which provider made it: a title from a major studio is handled exactly the same way as one from a smaller independent developer. We don't assign scores, ratings, or rankings, so there is nothing for a provider to buy a better position in. If a fact can only be found from a secondary source, we flag it as lower-confidence; if we can't confirm it at all, we leave the field blank rather than fill it with a guess. Everything on the site is a free demo with play-money credits only — there are no real-money outcomes tied to any figure we display.

How often does Slottomat update its game data?

Game data isn't static — providers patch games, ship new RTP versions, and release new titles — so we update our records as those changes are confirmed rather than on a fixed schedule. When a provider updates a game, we update the corresponding fields in our database from the provider's official information. Facts that were flagged as lower-confidence are queued for re-checking against the provider source. We don't publish a guaranteed update window or service-level commitment, and we don't run a formal periodic audit cycle. We also check demo availability on an ongoing basis: every game is meant to have a working free demo that loads with no download, no registration, and no real money, and demos that stop loading are flagged and hidden or removed so the playable set stays current. If you spot a value that looks wrong, you can report it through our contact page and we'll re-check it against the provider's official source.

Can I trust the demo slots on Slottomat to reflect real-money gameplay?

The demos on Slottomat are the free, play-money versions of each slot, loaded directly from the game provider, and they run on the same game software the provider distributes. That means the mechanics you experience — the reels, the bonus features, the volatility behavior — reflect how the game is built. The key difference is that you play with virtual credits, so there are no deposits, no withdrawals, and no real winnings. It's worth being precise about RTP and volatility: the RTP we display is the provider's stated, long-run theoretical figure, not a number we have independently re-measured, and it describes behavior over a very large number of spins rather than any single session. A short demo session can look very different from that long-run average, which is normal — slot outcomes are random. Use the demo to get a genuine feel for a game's features and how it plays. Slottomat is a free-to-play demo catalog and is not a casino; it does not take bets or offer real-money play.

How does Slottomat make sure the game facts it publishes are accurate?

Slottomat is a database-backed demo catalog, not a site built on individual reviewer opinions, so there is no human review team, no scoring panel, and no published certifications behind the facts we show. Accuracy comes from how the data is sourced and stored: every game is a structured record in our first-party database, each fact has its own field, and the value displayed on a page is read straight from that field rather than typed in by hand or copied from another listing site. When we create or update a record, the game provider's official information is the authoritative source. If a provider and a third party disagree, the provider's figure wins; if a fact can only be found from a secondary source, it's flagged as lower-confidence; and if we can't confirm a value from a trustworthy source, we leave the field blank rather than guess. We also check that each game's free demo loads and flag or remove the ones that don't. If you find a detail that looks wrong, report it through our contact page and we'll re-check it against the provider's official source and correct the record.

Editorial & Data Policy

How We Source Game Data

Slottomat is a database-backed demo catalog, not a site built on individual reviewer opinions. Each game page is generated from a structured first-party database record.

RTP Verification

We record Return to Player percentages from official game-provider documentation, cross-referencing provider sources including Pragmatic Play, NetEnt, Play'n GO, and others. RTP is the provider's stated theoretical figure, not a number we independently re-measure.

Demo Availability

We run automated checks that each game's free demo loads correctly; demos that fail are flagged and hidden or removed so you don't land on a dead page.

Content Standards

Each game page presents game mechanics, bonus features, volatility profiles, and playability. We do not score, rate, or rank games, and we make no claims about winning potential or gambling outcomes. All content is written in clear, accessible language.

Updates

We update game pages when providers release new versions or adjust RTP values. Pages display their last-updated date for transparency.

Independence of game data

The game facts we publish — RTP, volatility, max win, paylines — come from each provider's official information and are independent of any commercial arrangement. Casino offers shown elsewhere on the site are clearly-disclosed affiliate links and never change the game data.
