Methodology
How we verify the stats and write the reviews on rtpspy.com.
Published stats (RTP, max win, volatility)
Every slot fact we publish has been cross-checked across three independent industry sources: slotcatalog.com, bigwinboard.com, and aboutslots.com. A value only appears on a slot page after at least 2 of the 3 sources agree on it. When the sources disagree the field is left blank rather than guessed at — we'd rather show nothing than something wrong.
Newly announced slots (no industry coverage yet) start with provider-disclosed values from Slots Launch and get re-verified the moment review sites pick them up.
Live tracking (hit rate, big wins, current RTP)
The "live" numbers on each slot page (spins last 30 minutes, hit rate, recent big wins, biggest 24-hour multiplier) come from real-time bet feeds we ingest from nine crypto casinos: Gamdom, Shuffle, BC.Game, Stake, Razed, Thrill, Qzino, JackBit, and Degen.
Bets are normalised into USD using live exchange rates, capped at each slot's published maximum-win multiplier (so casino rounding artefacts can't fake a record-breaking spin), and deduplicated before they hit the database. Every bot writes a per-minute health snapshot we audit daily.
Reviews
Slot reviews are written by the RTPspy editorial team using a fixed template documented in our review standards. The author is given the verified DB stats and short prose context from the three industry sources, and is instructed to use the verified numbers as the single source of truth — never to invent a number or copy one from a third party. Every review states the slot's provider, headline stats, gameplay, bonus features, honest pros and cons, and a short verdict.
Reviews are regenerated when a slot transitions from upcoming to released (so the verdict reflects launch-day data, not the pre-release estimates) and on a rolling schedule for older slots whose underlying stats have changed.
What we don't do
- We do not accept payment for favourable reviews.
- We do not promise wins, payouts, or returns. Slots are random.
- We do not publish unverified stats — fields stay blank rather than guessed.
- We are not a gambling site. We track and analyse public bet data.
Corrections
