FAQ

Every day at midnight, your local time, five new puzzles open: one of each game. Everyone gets the same five that day. They start easy on Monday and get harder until Sunday’s expert puzzles.

The first time you open a game, a short tutorial teaches its rules on a small grid. Replay it any time in Settings › Tutorials, or tap ? next to the game’s name on a puzzle to see its rules.

No. Every puzzle has exactly one solution, and you can always reach it step by step with logic.

Hint shows the next step you can work out and explains why; Apply places it for you. Check highlights marks that don’t fit the solution. Use them whenever you like: that solve just won’t set a best time, count for “faster than”, or be compared in friends’ links. We ask once per puzzle before the first one.

Yes: on its result, tap the ↺ button, Practice this puzzle. A practice run doesn’t count: stats, streak and best times use only your first solve, and the practice result compares your new time with it.

Endless puzzles made on your phone, offline too. Pick a game, its level and its size. Every puzzle has a code: copy yours from the result, or play a friend’s with Play a puzzle code. Unlimited keeps best times for each game, level and size, and never changes your streak.

Yes: open the Archive and pick a day in the calendar. Past days count in your stats; your streak takes only yesterday’s, as a repair.

Solve at least one daily on its own day. A solve before 04:00 the next morning counts too, if you opened that daily on its day.

Every 7 days in a row earns a freeze, and you can hold 2. When you miss a day, a freeze covers it by itself, so your streak goes on.

If your streak broke yesterday, solve one of yesterday’s puzzles from Today or the Archive. That day then counts as if you solved it on time. You can repair once a week.

Past days count in your stats, not your streak. Only a repair brings a late solve into it.

Each day’s puzzles need a connection once. If you open the app and can’t get them, that day keeps your streak, up to twice a month. Unlimited works offline.

Every step a puzzle needs is rated 1 to 4, and the hardest one sets the level: Easy needs only steps rated 1, Expert a step rated 4. Tap the level on a result to see a puzzle’s steps.

It compares your time with everyone who solved the same daily cleanly: on its day, without a Hint or Check. It shows once enough people have solved it, moves during the day as more do, and settles the day after.

Share a result to send a link with your clean times. Your friend sees the same puzzles with your times to beat, and their result compares the two. A link holds only the puzzle number or code and the times, nothing about you.

Go to Settings › Appearance › Language. Until you pick one, Gridhaiku follows your phone’s language.

Yes. Settings › Appearance › Colour-blind mode gives colours that are easier to tell apart, region letters, and extra marks for mistakes. Every game can also be solved with VoiceOver or TalkBack.

Sign in with Apple or Google in Settings. Your streak and stats then follow you to any phone, iPhone or Android.

Check that Gridhaiku may send notifications and that battery saving doesn’t stop it. Some phones pause apps that haven’t been opened for a few days.

Open Settings and choose Delete my data under Privacy. If you’re signed in, open your account in Settings and choose Delete account. Either way your streak, stats and progress are deleted from our servers and your phone. Without the app, see Delete your account.

Settings › Help › Contact support opens an email with your app version, phone and Support ID filled in, so we can look into it quickly.
