The current service
The first pack contains 30 missions and 210 questions shared across English, Spanish, French, German, Portuguese and Chinese. Play is single-player, with progress saved in this browser when storage is available. This version has no player accounts, groups, cloud saves or global rankings. Moon Juego’s questions and saves are separate from the original One in a Moon service.
Playing and recording a result
Each mission has seven questions. A question gives three seconds to read and then 25 seconds to answer; the first accepted answer closes it. Fixed scores are 10, 30, 60, 85 or 100 metres, with zero for an unanswered question and a maximum of 700. Refreshing or changing language does not reset the deadline. Daily first results and archive replays have separate local records; clearing storage or changing browsers does not preserve the same save.
Editorial questions and scoring
Questions define their own valid-answer sets and cite factual sources. Registered names and aliases in all six languages can identify the same answer. Spelling suggestions require confirmation, and ambiguous names require a choice. Score levels are editorial estimates, not measured player percentages. Questions and accepted lists may need correction; use the contact page to report a specific issue.
Availability and updates
Scheduled daily missions open at 09:00 in Europe/Madrid, including daylight-saving changes. Once the 30-mission pack ends, released past missions remain in the archive; new questions are not promised automatically. Reloading, changing language or leaving the page does not pause a running question’s deadline. Browser settings, storage removal and access to the site can affect play and saving. Keep any downloaded copies you wish to retain.
Original material and cited works
Moon Juego has its own game code, artwork and written questions. Cited factual sources and referenced works or marks are not claimed as our property; any stated third-party licence still applies to that material. The site is inspired by One in a Moon but is not its publisher or account service. You may share the result text supplied by the game, and source or rights concerns can be raised through the contact page.
