Euclidle is a browser puzzle that turns number guessing into a search through coordinate space. A player submits coordinates and uses the resulting Euclidean distance and color clues to work toward a hidden point. Its tutorial starts with a two-dimensional example, showing how successive guesses can reveal whether a move approached the target, moved away or passed it along an axis.
The interface combines a history of guesses with a visual hint display, and the documentation describes higher-dimensional challenges and an Expert mode that removes coordinate hints. Instead of testing word knowledge, the game invites deductions about distance, direction and boundaries. The daily board shown on the site uses a UTC date, which matters when comparing a result across local time zones. Euclidle includes a tutorial game and a manual for learning the clue system, along with several interface languages. It is suited to players who enjoy compact logic problems and spatial reasoning, while the guided example gives newcomers a way to learn the mechanics before attempting a harder board.
