Methodology
Frame a price is designed as an educational entertainment game, not a shopping engine. The catalogue uses editorial gameplay anchors for recognisable product types so visitors can practise estimating ranges and notice how everyday goods differ between markets.
Products are chosen because they are familiar enough to guess and varied enough to make the game interesting: technology, home appliances, food, furniture, sports, baby products, health, beauty, travel and other everyday categories. The goal is a broad benchmark of common consumer goods rather than a catalogue of exact offers.
The game compares rounded anchors for France, the United States, Japan, the United Kingdom and Germany. European, UK and Japanese anchors are intended to resemble consumer-facing tax-inclusive prices; US anchors follow the common pre-sales-tax display convention because the final tax varies by location. The figures are not normalised into a tax-exclusive statistical series.
Each product has five rounded editorial gameplay anchors. When you select a display currency, the game converts those anchors using a fixed gameplay-normalization table effective 16 September 2026, so a session does not change during play. The table is not a live rate or a claim about a transaction rate. Slider ranges are generated around the converted anchor. Currency conversion does not turn the anchor into a retailer quote.
Market prices can change quickly because of promotions, exchange rates, stock, retailer policies and delivery costs. Values shown in the game should be read as approximate reference points for guessing practice, not live quotes, purchasing advice, financial advice or promises that a product is available at a specific retailer.
The product description defines the unit being guessed—capacity, size, tier or service format. It is a representative specification, not an unnamed claim about every model in the category.
Anchors are manually maintained, rounded category estimates for guessing practice. They are not collected as 500 simultaneous retailer observations. Similar products may intentionally share a rounded tier; that does not mean retailer prices are identical.
The catalogue was reviewed on 3 October 2026. A review checks specifications, obvious outliers, images and wording. Public evidence supplied with a correction request is considered, but the game does not promise a fixed update interval or historical price series.
Product identifiers, country coverage, image URLs and explanatory fields are checked programmatically before release. Wording and unusual values are then reviewed manually. Software may assist with drafting and duplicate detection, but changes are not published autonomously.
Guide pages link to independent public authorities for further reading. Those sources support general comparison principles; they do not supply or endorse the site’s indicative values. Advertising and affiliate links do not decide which products appear or how a reference value is set.
Read the full editorial standards →If a price, image, category or explanatory note looks outdated, use the contact page and include the product name, country, an approximate observed market value and a public reference if available. Corrections are reviewed manually so the game stays understandable and fair without pretending to be a live price-comparison database.
