What we count, how, and what we don’t.

From an operator’s lobby to a report

1. ReadEvery licensed lobby, web and mobile, once a day.
2. IdentifyEvery card matched to its game and provider, or left unnamed.
3. ScoreEvery measured position gets a Visibility Score.
4. CompareEach lobby against its own previous observed day.
5. ProveEach read keeps the screenshot its positions came from.

What we track

Slotmetry tracks the games that compete for the same lobby space: slots and crash games.

What a position is

A position is one card slot on a lobby page. It is the unit every lobby number is built from.

• Positions are grouped in sections, in the page’s order: a ribbon, a grid, or the single list of a lobby without sections.
• Each position has a place inside its section and an absolute place on the page.
• A game shown in several sections holds several positions, and every one is recorded.
• A position whose game we cannot identify stays in the totals and is never given a name.

Games, providers and studios

• An identified game carries a game, a provider and a category. Only identified games are counted as games.
• Numbers are read by provider, the company that distributes the game today.
• A provider owned by an operator group is marked as in-house.

Visibility Score and share

• The Visibility Score measures how well a card can be seen where it sits. Position 1 of a lower section can be better seen than position 10 of the first.
• Visibility Share is a provider’s, or a game’s, part of all the visibility a market or a lobby gave.
• Every provider or game figure can be read against the market reference: what a typical provider or game holds in the same market, days and device.

Change over time

• Each lobby is compared with itself, never with another operator or market.
• Day to day, every identified game’s position is new, moved or unchanged against the same lobby’s previous observed day.
• A count over several days is served as the mean of the days, never as a total that grows with the period.

The catalogue

• The lobby is what an operator shows. The catalogue is everything it offers: every game it carries.
• A release is one game on one operator: one game carried by five operators is one game and five releases.

What the data does not tell you

Slotmetry shows what operators put in their lobbies and catalogues. It says nothing about why, or what happened next.

Markets

Only licensed operators are read, and a market goes live only when all of them are read in full.
