About Ping

Ping is a free daily geography game from Source of Truths — the daily city hunt. Each day there’s one secret city somewhere in the world and not a single clue to start. Name any well-known city and Ping answers with one number: the great-circle distance in miles to the target.

From there it’s pure triangulation: watch the miles fall and close in on the answer. There’s no limit on guesses, so everyone gets there in the end — the goal is to do it in as few guesses as you can. Give up any time and you’re still scored on how close you got. One free hint reveals the continent.

A new city drops every day at midnight Eastern, with a trickier one on Sundays. No app, no signup — play free in your browser, keep a streak, and race the daily leaderboard. More dailies: Span, our geography game, Circa, the daily year hunt, and Crux, our clueless crossword.
