How to play Crease Game
Crease Game Online is a free daily paper folding puzzle for your phone or computer. You drag a square sheet to fold it until the paper covers a dashed outline exactly: the same shape, in the same place. This guide covers the three moves every beginner needs. Each one has a playable lesson in the game.
The rules in 20 seconds
- Goal: make the visible paper cover the dashed outline exactly. Nothing hanging over, nothing left uncovered.
- Move: press on the paper and drag. The spot you grab lands where you let go, and the paper folds along the crease halfway between.
- Score: par is the fewest folds that can solve the puzzle. Match par with no hints for three stars.
Step 1 Make your first fold
In lesson 1, “Fold in half”, the outline covers the left half of the sheet. Grab the right half and pull it across the middle.
Folds snap to the creases on the mat: straight lines along the grid, or 45° diagonals. If a fold isn't allowed, the snap line turns red and the paper slides back when you let go. A fold isn't allowed when the flap would land off the mat or the crease doesn't cross the paper. No fold is counted.
Try lesson 1: Fold in halfStep 2 Make a diagonal fold
Lesson 2, “Corner to corner”, asks for a triangle. The direction you drag picks the crease: straight across for a straight fold, about 45° for a diagonal one.
When paper flips over, its white back faces up. Layers that stack up look a little darker, so you can always see how the sheet was folded.

Position matters as much as shape. Here the outline is the right half, but the first fold put the paper on the left.
Lesson 3, “Two folds”, practises this: two folds, where the order and side decide where the paper ends up.

- 2½ sq outside the outline · 1 sq of outline uncovered
- How far off you are, in grid squares. Red stripes show the overhang when Differences is on.
- Right shape, wrong place!
- The shape matches but sits elsewhere. Undo and fold from the other side.
- Too little paper is left to fill the outline.
- Folding never adds paper back. Undo or restart. The paper's face looks worried here too.
- Hint
- Plays a see-through fold showing the next move of a shortest solution. Hints cost a star.
- Par and stars
- Par is the true minimum number of folds, checked by computer. Every fold counts, including folds you undo.

Questions from new players
Is Crease Game Online a Wordle-style paper game?
Yes, in the ways that matter: there is a fresh set of puzzles every day, everyone gets the same puzzles on the same date, and you can share your stars without spoilers. Instead of guessing a word, you fold a square of paper until it matches a dashed outline.
How do I make a diagonal fold?
Drag at roughly 45 degrees, for example from a corner toward the opposite corner. Any drag close to a diagonal snaps to the nearest diagonal crease. Slanted edges on the outline almost always need a diagonal fold.
What does “right shape, wrong place” mean?
Your paper has exactly the outline’s shape, but it sits somewhere else on the mat. Undo the fold and fold from the opposite side, or in a different order, so the paper lands on the outline.
Do undone folds count?
Yes. Every fold you make counts toward your total, including folds you undo. Solve in par with no hints for three stars, within two folds of par with at most one hint for two stars, and any solve earns one star.
