Data & Methodology
Nobody can honestly tell you a slot’s RTP today. What we can show is the manufacturer’s long-run RTP, and a measured return for a labelled past window, with sample size and error bars when the feed publishes them.
Stats product, not a casino. No bonuses on this page.
What we measure
We ingest published studio feeds and show two kinds of number when they exist. Observed RTP is payouts divided by stakes for a defined past window on that feed (for example BGaming Hub 7-day stats, or Playin OSS short windows). Theoretical RTP is the manufacturer’s long-run design figure when only studio maths is public. Each row keeps its own window or theo label.
How we compute and label
Observed RTP = (payouts ÷ stakes) × 100 for the window printed on the row. Rounds and confidence appear when the source publishes them; otherwise the cell stays n/a. We do not invent precision. Windows of different lengths are different signals. A 1-minute figure is not interchangeable with 1 hour or 7 days.
What we do not claim
We do not claim “RTP today,” that a row is due to hit, or that past observed return predicts the next spin. We do not offer gambling, accounts, deposits, or bonuses on this site. We do not invent licenses, jurisdictions, or partner bonus figures in our own copy.
Commercial links
Some outbound links are commercial (sponsored) links to partner sites. If you follow them and sign up, we may earn a commission. That does not change board numbers, sort order, filter logic, or how we label observed vs theoretical. Rankings and filters follow the data rules on this page, not paid placement.

Responsible gambling
18+ (or the legal gambling age where you live, if higher). RawRTP is not a casino and takes no wagers. It is an information board only: we do not offer gambling, accounts, deposits or bonuses. Gambling may be restricted or illegal where you live, so check your local laws. If you gamble, set limits and get help early.
Short definitions
Theoretical RTP (studio)
The long-run expected return from the game’s certified model. Studios often publish this as advertised or declared RTP. It describes the design, not one short session.
Observed RTP (live window)
Payouts divided by stakes, times 100, for a defined published period from a studio feed we show. It describes that past window only.
Why the numbers diverge
- Finite samples wander. Short windows are noisy; a rare big win can move the percentage a lot.
- Window length matters. A 1-minute figure is not the same signal as 1 hour or 7 days - never treat them as interchangeable.
- Some titles ship at more than one theoretical RTP. An operator’s config can differ from the figure next to a row.
- Observed above 100% in a window means payouts exceeded stakes in that dataset. It does not mean the next session will.
How RawRTP labels rows
We show observed when a studio publishes a live feed we ingest - for example BGaming Hub 7-day stats, and Playin OSS short windows for listed providers (including NoLimit City, NetEnt, Red Tiger, Big Time Gaming where that feed applies).
We show theoretical when only studio maths is public - for example Yggdrasil, Endorphina, Push Gaming, Pragmatic Play, Hacksaw Gaming, Thunderkick, Wazdan, Skywind, Fantasma, Kalamba, and AvatarUX rows where rtpObserved is empty. Those rows stay labelled theoretical; we do not call them live.
Each row carries its own window or theo label. Do not mix signals across rows or windows.

FAQ
What is observed RTP?
Observed RTP is payouts ÷ stakes × 100 for the past window printed on the row. It describes that window only and is not a forecast.
How often is the board updated?
The board is rebuilt once an hour by a scheduled job. Each row keeps the label of the window it describes.
Can you show a slot’s RTP today?
No. A short live window is a past sample, not “today’s true RTP.” We show manufacturer (theoretical) RTP when we have it, and observed return for a labelled window when a studio feed publishes it.
What is manufacturer vs measured?
Manufacturer RTP is the long-run design figure from studio maths. Measured (observed) RTP is payouts ÷ stakes for the window printed on the row. They answer different questions.
Why show error bars / rounds / confidence?
Short samples wander. When the feed publishes rounds or a confidence band, we show them so thin heat is visible instead of hidden.
Does a hot or high observed row mean the next spin will pay?
No. Past window only. Not a forecast and not advice to gamble.
