Crease Bound

Support & contact

Crease Bound is a turn-based puzzle game for iPhone and iPad. You fold one outer edge of a notebook page inward per move, guiding a doodle to its way out before the scribble monsters or the rising ink tide catch it. To fold, swipe anywhere on the page the way you want the paper to go: swipe left and the right edge folds over.

Questions, bug reports, or feedback are welcome. Email qblink.techno@gmail.com and I'll get back to you.

It helps to include your device model, your iOS version, and the level number where the problem happened.

Meet the characters

Everyone who lives on the page, and what each one does.

The Doodle

This is you

A little drawing who wants to get off the page. The Doodle cannot walk by itself. It sits on the paper, so when you fold the paper, the Doodle comes along for the ride.

Your job: fold the page until the Doodle reaches the way out.

The Way Out

Your goal

A hole in the paper with a green glow around it. Get the Doodle onto this spot and you win the level.

Remember: the way out sits on the paper too, so folding moves it as well. Watch where it ends up.

Scribble

The chaser

Scribble walks straight at you. Every time you fold the page, it takes one step closer to the Doodle.

How to beat it: it is the easy one to guess. Think about where the Doodle will be after your fold, not where it is now.

Crease Runner

Runs along the fold line

When you fold the page, a new line appears where the paper bent. That line is called a crease. The Crease Runner runs along it, like a train on a track.

Fold the left or right side and it moves up or down. Fold the top or bottom and it moves left or right. Look for the dashed track under its feet.

Fold Skitter

Runs away from your fold

The Fold Skitter is a scaredy-cat. It always runs away from the side you just folded, and it never even looks at the Doodle.

Fold the left and it scoots right. Fold the top and it scoots down. That means you decide where it goes — so you can push it somewhere safe. If the push would send it off the page, it just stays still.

Crease Crosser

Steps across the fold line

The Crease Crosser is the Crease Runner's opposite. Instead of running along the crease, it steps straight across it, toward the Doodle.

Fold the left or right side and it steps sideways at you. Fold the top or bottom and it steps up or down at you. Look for the bar with an arrow on both ends.

Line Watcher

Wakes when you line up

The Line Watcher sits perfectly still — until the Doodle comes within one line of it: its row or column, or the one right beside it. Then it wakes up and chases like Scribble, one step every fold.

Watch out: once it is awake it never goes back to sleep, because folding only ever brings things closer together. Keep out of its lines for as long as you can. It first appears at Level 71.

The Ink Tide

The clock

Dark ink creeping up the page. It is not a creature and it does not chase anyone — it simply rises a little bit every time you fold.

Watch out: the tide only moves when you do, so there is no rush and no timer. Take as long as you like to think. But try not to waste folds.

A handy trick

If you fold the paper over a monster, it gets pinned underneath and turns grey. A pinned monster cannot chase you any more. Trapping a monster under a fold is often the tidiest way to solve a level — and it is free.

The Power Boost Updated in 3.3

Beaten by a level? A Power Boost is a pushpin you can spend to pin any one monster where it stands. A pinned monster stops moving and can no longer catch the Doodle for the rest of that attempt. It stays on the page — it is not destroyed — but it is out of the game.

Tap the pushpin at the bottom of the board, then choose the monster you want pinned. Spending one is not a move: it uses no fold and does not raise the ink tide.

Finishing a level with a Power Boost still completes it and still unlocks the next one. A Power Boost cannot rescue an attempt that has already ended, though, so spend it before you are caught.

Hints New in 3.2

Can't see the way? Tap the light bulb next to the pushpin at the bottom of the board. The edge of the page you should fold next lights up, with an arrow showing which way to swipe, and the line above the buttons says it in words. A hint shows you one fold — never the whole solution — and it works out that fold from the page as it is right now, not from the start of the level.

Hints are optional. Every level can be solved without one, and finishing a level with a hint still completes it.

Watch an ad New in 3.3

Running low? Watch a short ad to earn one Power Boost and one hint. It is entirely up to you: an ad only ever plays when you tap Watch an ad, and there are no banners and no ads between levels.

Ads are served by Google AdMob, are not personalised, and are suitable for all ages. See the privacy policy for what Google receives when you watch one.

How hard is this page? New in 3.3

Every level now shows how hard it plays. Easy pages are cream, medium pages butter-yellow, and hard pages blush pink — on the board and on the level map. The level header says Easy, Medium, or Hard in words too. Difficulty does not simply rise with the level number: a few calmer pages sit among the hardest ones.

Common questions

How is my progress saved?
Entirely on your device. Completing a level records it immediately, so closing the app — even force-quitting mid-level — never loses a solved level.
Is there an account or a sign-in?
No. Crease Bound is single-player and works fully offline. There is nothing to register and no server to connect to.
Does the game need an internet connection?
No. Every level ships inside the app and the game makes no network requests of its own. Only buying Power Boosts and hints, or choosing to watch an ad, needs a connection.
Can I replay a level I've already solved?
Yes. Any unlocked level can be replayed from the level select grid at any time.
I'm stuck on a level. Is it definitely solvable?
Yes. Every level ships with a verified solution — each one was checked by a solver against the same rules the game plays by, so none is impossible.
Can I undo a move?
Not from version 2.0 onwards. Restart is the way back, and it is always available from the board and from the pause menu. Restarting begins the level again from the start. From version 3.0 it does not return Power Boosts you spent on that attempt.
What is the Power Boost, and how do I get more?
It pins one monster in place for the rest of the attempt, so it can no longer chase the Doodle. You start with 3, and every 5 levels you complete you collect one more along with a hint. See The Power Boost above.
How do hints work?
Tap the light bulb and one fold that still wins lights up on the page. It is used up when shown, unless there is no way left to win, in which case it says so and costs nothing. See Hints above.
Do Power Boosts and hints cost money?
They don't have to. You earn both by playing, and every level can be solved without either. You can also watch an ad, by choice, for one of each. If you run out, you can buy 7 Power Boosts with 5 hints, or 20 with 10 hints, as an in-app purchase. There are no subscriptions and nothing else for sale.
Does Crease Bound have ads?
Only if you ask for one. An ad plays only when you tap Watch an ad to earn a Power Boost and a hint. There are no banners and no ads between levels. See Watch an ad above.
How many levels are there?
One hundred. Levels 1–50 teach the first four monsters and the ink tide; Levels 51–70 are two late-game chapters that add no new rules. Levels 71–85 bring in the fifth and final monster, the Line Watcher, on the biggest pages in the game, and Levels 86–100 close the book with the hardest puzzles of all — again with no new rules.
I played an earlier version — do I keep my progress?
Yes. Updating keeps every level you have completed and every Power Boost you hold. Coming from 1.0, you also receive the 3 starting Power Boosts, and updating to 3.2 gives everyone the 3 starting hints.
When do the new monsters appear?
Scribble is there from the start. The Crease Runner joins at Level 16, the Fold Skitter at Level 31, the Crease Crosser at Level 41, and the Line Watcher at Level 71 — so each one gets introduced on its own before they start mixing.
How do I turn off sound or haptics?
Open Settings from the pause menu or the Home screen. Sound and haptics are controlled separately.
I use Reduce Motion. Does the game still work?
Yes. With Reduce Motion enabled, animations are simplified but no gameplay information is lost.
What devices are supported?
iPhone and iPad running iOS 26 or later. The game is played in portrait.

Release notes

What changed in each version, newest first.

Version 3.3
  • New: watch an ad, if you like. Running low? Watch a short ad to earn a Power Boost and a hint. Ads only play when you tap to watch one. See Watch an ad.
  • Pages show how hard they are: cream for easy, butter-yellow for medium, blush pink for hard. See How hard is this page?
  • No changes to any level, its solution, or the rules.
Version 3.2
  • New: hints. Tap the light bulb and one fold that still wins lights up on the page. You start with 3. See Hints.
  • Rewards to collect. Every 5 levels, collect a Power Boost and a hint on the results screen. A reward you leave there waits on the title screen.
  • Bundles now include free hints: 7 Power Boosts with 5 hints, or 20 with 10 hints. Same prices.
  • Fold from anywhere. Swipe across the page the way you want the paper to go — you no longer have to start at an edge, and swipes near the bottom of the screen fold the page instead of switching apps. Dragging an edge still works.
  • No changes to any level, its solution, or the rules.
Version 3.0
  • Thirty new levels. The book now runs to 100, across four new chapters: The Watching Page, The Last Page, Margin Notes and The Back Cover.
  • A new monster: the Line Watcher. It stays still until the Doodle comes within one line of it, then chases for good. It is the fifth and final monster.
  • Bigger pages, up to 10 by 14, with a tighter layout on smaller iPhones so every square stays easy to read and tap.
  • Power Boosts are now used up for good. Restarting a level no longer returns the ones you spent, and there is no longer a limit on how many you can hold.
  • Buy more Power Boosts if you run out: 7 or 20, as an in-app purchase. The store only appears when you have none left. You still earn one for every 5 levels you finish.
  • The Power Boost button now shows just the pushpin and your count.
  • No changes to Levels 1–70, their solutions, or the rules. Anything solvable in 2.0 is solved the same way in 3.0.
Version 2.0
  • Twenty new levels. The book now runs to 70. Levels 51–70 are two late-game chapters that introduce no new rule — the difficulty comes from how the pieces on the page depend on each other, and from the order you fold in.
  • Levels is now a chapter map. Paper tabs name each chapter, a pencil trail runs through its levels, and it opens on the chapter you are actually up to.
  • New: the Power Boost. Spend a pushpin to pin one monster in place for the rest of the attempt, so it can no longer chase you. You start with 3 and earn more as you finish levels. See The Power Boost.
  • A full results screen. Finishing a level now opens a screen of its own instead of a small card over the board, showing how the attempt went and what it earned, with Next Level, Replay, Levels and Home.
  • A help deck. Tap the ? on the title screen or at the end of the row beneath the board for cards explaining the fold, where the page lands, and each creature you have met so far. It never shows a creature you have not met, and it gives no hints about the level you are playing.
  • Undo has been removed. Restart is now the way back, and it refunds any Power Boosts spent on that attempt.
  • A rating prompt. After you finish the first chapter the game asks once, using Apple's standard prompt, whether you are enjoying it. It asks at most once per version, and never after a level you lost.
  • No changes to Levels 1–50, their solutions, the fold rules, or how the monsters behave. Anything solvable in 1.0 is solved the same way in 2.0.
Version 1.0
First release. Fifty levels, four kinds of scribble monster introduced a few levels apart, the rising ink tide, level select with saved progress, and full Reduce Motion support.
