Before you play
Is every day's picture new?
A collection of 30 original pictures rotates by the calendar in Korea (KST). Everyone gets the same picture on the same day, in every language. The collection repeats after 30 days.
Where is my progress saved?
Only in this browser, for up to 90 recent boards. Daily and practice progress are separate. Switching languages keeps your board. Clearing browser data removes it; records do not sync between devices.
What does a hint do?
It corrects one wrongly marked square, or marks one unknown square correctly. Undo and clearing the board never erase the hint count. There is no timer or leaderboard.
Can a friend see my answer?
Puzzle links contain no square marks or answers. A friend opens the same puzzle with their own local progress. The downloadable result card also hides the completed picture.
