Methodology

Slot data

Spinotter pages use structured source data including game name, provider, thumbnail, demo availability, RTP, volatility, release date, mechanics, and theme information where available.

Games with missing core display data or unsuitable values can be excluded from the retained catalogue to keep the site useful and manageable.

RTP and volatility sourcing

RTP, volatility, and related mechanics come from structured feeds supplied by slot providers or dedicated slot-data sources, not from estimates or gameplay sampling.

Where a source records when a figure was last checked, that date is shown next to the figure on the game page. A game with no published RTP has not had a figure supplied by a connected source; it does not mean that the value is unpublished or hidden.

Some sources mark facts as studio-verified and others do not. Where that distinction is known, Spinotter keeps it separate from the figure itself rather than implying verification.

Ranking and filtering

Search and category pages use available structured fields such as release date, RTP, provider, volatility, and features. They do not guarantee that a game is available in every country or at every casino.
