Sources & Methodology
Page updated: 22 October 2026 · This reference page is available in English.
What the game compares, how to read its numbers, and where to check a fact.
A fixed collection, not a live ranking
The game uses a curated collection of trivia values assembled around mid-2026. The collection includes older reports: its creation date is not a common reference date for every figure. Individual source dates were not recorded consistently. Values are fixed within this release and are not fetched from the linked sites during play.
The links below are references for checking figures, not a claim that each existing entry was originally taken from, or recently reverified against, that source. This release adds clearer definitions and checking links; it does not certify the entire dataset as current. For a current figure, follow a dated source and check the precise edition, platform, territory or model.
Comparison rules
Choose whether the hidden value is higher or lower than the revealed value. Comparisons use the stored numbers shown by the game. Equal stored values count as correct for either answer. Rounding can create ties, and new estimates can reverse the order of close values. The game is for entertainment; its comparisons are not a guarantee of current real-world rankings.
| Category | Comparison and limitations | Checking references |
|---|---|---|
| Best-Sellers | Approximate lifetime game sales, in millions of copies. Some labels combine editions; bundled copies and publisher reporting dates can differ. This is a selected collection, not a complete sales chart. | Nintendo sales disclosures Take-Two investor reports |
| Critic Scores | Metacritic critic scores out of 100. Platforms and editions may have different scores; use the platform subtitle where recorded. Entries labelled “Multi” do not specify a single platform and should not be interpreted as a calculated cross-platform average. | Metacritic games |
| Newer or Older | The original release year stored for each game, not the year of its latest port or remaster. Different regional release dates can fall in different years. | Nintendo game listings Steam product listings (check whether a date describes the port) |
| Geography | Rounded country-population estimates, in millions. These are legacy estimates and must not be read as current 2026 populations. Population estimates, census counts and projections have different dates and methods. | UN World Population Prospects |
| Space | Approximate diameters of selected solar-system bodies, in kilometres, not radii or distance from the Sun. Irregular bodies can have more than one meaningful diameter; the collection uses a single simplified value. | NASA Solar System Exploration |
| Movies & TV | The current dataset contains films, compared by approximate worldwide lifetime box-office gross in millions of US dollars. Values are not adjusted for inflation and may predate later theatrical re-releases. TV ratings and streaming views are not compared. | Box Office Mojo worldwide lifetime chart |
| Books | Estimated copies sold, in millions. Historical totals can be uncertain and may treat translations, editions or series differently. These are estimates, not audited circulation or library holdings. | Best-selling books reference list and its cited publisher reports |
| Pokémon | National Pokédex number, not strength, popularity or a regional Pokédex position. These identifiers are fixed for the listed species. | Official Pokédex |
| LEGO | Piece count for the set edition represented by the entry. Several products share a name; use the set number when supplied. Replacement editions and other sets of the same subject may have different counts. | LEGO set and instruction lookup |
| FIFA World Cup | Men’s World Cup finals-tournament appearances through 2022. The collection excludes 2026 and qualifying rounds. Historical predecessor-team attribution can affect country totals. | FIFA World Cup tournament information |
| Cars | Headline peak power for selected model variants, displayed as horsepower. This is not acceleration, top speed or sustained output. Variant, model year, boost conditions and manufacturers’ use of hp or metric PS can affect comparisons. | Rimac Nevera specifications Lotus Evija specifications; check the relevant maker for other models |
Original illustrations and names
Cards use original category illustrations and lettering supplied with this site. They do not load cover art, character images or product photographs from Wikipedia, Steam or another remote image library. Illustrations represent a category and are not documentary pictures of each item. Names such as Pokémon, LEGO and FIFA identify the subjects of trivia; their owners do not endorse or operate this website.

For edition-sensitive figures, include the platform, set number or model variant. A correction can change a close comparison, which is why the game should not be used as a current factual ranking.
