How to play
- Tap a cell to flip it and its up, down, left and right neighbors.
- Turn every light off. Par is the fewest moves possible.
- One new puzzle each day at midnight. Solve daily to build your streak.
Tip: go row by row, tapping the cell below each lit cell. Lights left on the bottom row? Try different moves on the top row.
In the app, Help shows the rules again and lets you replay the tutorial.
Questions
Is every puzzle solvable?
Yes. Par is the true minimum number of moves for that day’s board, so solving it at par is always possible.
When does the new puzzle arrive?
At midnight, using your iPhone’s local time. Everyone gets the same puzzle for the same date. Puzzles start gentle on Monday and get tougher through the week, up to Sunday.
Can I play more than one puzzle a day?
Yes. Once you’ve solved today’s puzzle, tap Practice for as many extra boards as you like. Practice boards never change your streak, your stats or your share card. You can’t replay earlier days’ puzzles.
Why did my streak reset?
A streak counts days in a row with a solved puzzle. If you miss a day, it starts again. Your best streak is kept. Changing your iPhone’s date, time or time zone can also affect it.
What’s in Stats?
Puzzles solved, your current and best streak, how often you hit par (your Perfect rate), your average moves over par, a chart of moves over par, and your last 14 days.
How do I turn the reminder on or off?
Go to Settings › Reminders. The reminder comes at 7 PM your time, only on days you haven’t played yet. You can’t change the time in this version.
I turned the reminder on but didn’t get one.
Check that notifications are allowed for Unlit in your iPhone’s Settings › Notifications. If they’re off, the app’s Settings shows Reminders as Off, with a link to turn them on. A Focus mode can also hold notifications back. And no reminder comes on a day you’ve already played.
Can I change the colors?
Yes. In Settings › Display, choose System, Light or Dark. If Increase Contrast is on in your iPhone’s Accessibility settings, Unlit uses higher-contrast colors.
How do I turn off vibration?
Settings › Feedback › Vibration.
How do I erase my data?
Settings › Data › Erase all data… removes everything Unlit has saved on your iPhone, including your streak and stats, and cancels any reminder. It can’t be undone.
I deleted the app, or got a new phone. Can I get my progress back?
Usually not, sorry. There are no accounts, so your progress lives only on your iPhone and we can’t see or restore it. Restoring a full backup of your phone may bring it back, but we can’t promise that.
Is there an Android or iPad version?
Not yet. Unlit is made for iPhone first.
Does it have ads or collect data?
No. See the privacy policy.
Report a problem
Email support@tinwren.com with:
- your iPhone model and iOS version;
- the app version, shown at the bottom of Settings;
- the puzzle number shown at the top of the screen;
- what you tapped, what you expected and what happened;
- a screenshot or screen recording, if you can.
Unlit itself sends nothing. If you’ve turned on Share With App Developers in your iPhone’s settings, Apple may pass us anonymous crash reports, but they can’t tell us what you saw, so a note from you helps most.
