YAOKU Daily puzzle
One generated number puzzle is shared by everyone for each America/Chicago calendar day. Open today’s Daily to work with the same starting clues and Loose Cards as other players; no account is required.
When does the Daily reset?
A new Daily becomes available at midnight America/Chicago. The reset follows that time zone’s daylight-saving changes, not a fixed UTC hour or your device’s clock. Players in other time zones may see the next Daily begin earlier or later in their local day.
The server chooses, generates, verifies, and saves the day’s board. You need a connection to open the current Daily. If it cannot load, use the game’s retry option rather than changing your clock.
What happens to a puzzle already in progress?
An edited board is kept when a new Daily becomes available. Use “Open today’s Daily” in the game to switch when you are ready. Your entries and notes are saved only in this browser on this device; they do not automatically follow you to another browser or device.
Share the board or share your result
A six-digit puzzle link lets someone open the exact starting board without your entries or notes. After finishing, result sharing can include completion time, hints used, and an optional visit streak. It does not include your local player name or solution. A visit streak records visits, not consecutive Daily wins.
Between Daily puzzles
Random generates fresh Easy, Medium, or Hard boards in your browser. YAOKU has no fixed puzzle collection or public leaderboard. All modes use the same crossing-sum, product-badge, and Loose Card rules.
