Frequently asked questions
Does the puzzle of the day change every day?
Yes. Puzzles are picked by date; everyone sees the same one on the same day, and a new one arrives the next day.
Are my results sent anywhere?
No. Progress and streaks are stored only in this device's browser. The share button only prepares the result text; you decide where to send it.
Is time measured?
No. There's a move count and a goal, but no timer. Take your time to think.
Can the whole class solve the same puzzle?
Yes. Everyone who opens it on the same day sees the same puzzle; you can also solve it together in whiteboard mode.
