About WikidataGuessr

Game Overview

WikidataGuessr is a GeoGuessr-inspired game that challenges players to identify locations based on images from Wikimedia Commons and geographic data from Wikidata. Unlike commercial alternatives, this game is completely open-source and uses freely available data from the Wikimedia ecosystem.

Interactive Map

Make your guesses using an interactive OpenStreetMap interface with precise distance measurement.

Multiple Images

View multiple images per location with a slideshow interface to get different perspectives.

Scoring System

Earn points based on how close your guess is to the actual location, with exponential scoring.

Open Data

All data comes from open sources - Wikidata for locations and Wikimedia Commons for images.

Open Source

The complete source code is available on GitHub for anyone to use or modify.

Frequently Asked Questions

Why are some locations not very recognizable?

The game uses completely random locations from Wikidata that have geographic coordinates and at least one image. Some locations might be less recognizable than others - that's part of the challenge!

Can I suggest improvements or report bugs?

Yes! Please open an issue on the GitHub repository with your suggestion or bug report.

Is there a mobile app version?

Currently WikidataGuessr is web-only, but the responsive design works well on mobile browsers. An app version may be developed in the future.

How often is new content added?

The game doesn't have a fixed content set - it dynamically queries Wikidata and Wikimedia Commons, so new content becomes available as it's added to those platforms.
