Questions people ask

Do I need an account?
No, and there is not one to make. Your streak, stats and unfinished boards live on your device.
What happens if I clear my browser data?
Your streak and stats go with it. Cloud saves are on the roadmap; until then, the honest answer is that the data is only as durable as your browser storage.
When does the daily puzzle reset?
At midnight in your own time zone. There is no advantage to being in a particular one.
Are the puzzles the same for everyone?
Yes. Each day maps to a fixed set of boards, so you and a friend on the other side of the world get the same three — or the same ten.
Do archive replays affect my streak?
No. Only finishing today’s run banks a day. Replays are recorded separately, so the archive is a safe place to experiment.
Does a hint cost me anything?
Only pride. Hints are counted and shown at the end, and there is a short cooldown between them so the button cannot quietly become a solve button.
Can I just see the answer?
Keep taking hints. Each one is a real deduction with a name, so working through them teaches you the technique instead of handing over the grid.
Do you show ads or sell data?
No ads. Analytics records which pages get played, not who you are, and the privacy page has a switch that turns it off.
