Crease Game, the paper folding puzzle. A little fold. A big aha!

Start with a fold

How to play Crease Game

1. Look at the target. The dashed outline shows the shape and position you are aiming for.
2. Grab and drag the paper. Pull a point toward where you want it to land. The preview shows the fold before you let go.
3. Release to make a crease. Folds snap to horizontal or vertical guides. Some levels also allow diagonal folds, and each fold moves all the layers on that side.
4. Match the shape. Watch the match percentage as you fold. Solve within the reference fold count without hints to earn three stars.

Use Undo to unfold the paper, Restart for a fresh sheet, or Hint to see the next reference crease and drag direction. Choose Easy, Medium, or Hard, with three new puzzles in each difficulty every day. Open Earlier levels to revisit a date or learn with the original folding lessons.

For small folds, choose a finer Fold grid, down to 1/32 of the original sheet. Use the zoom buttons and Move view to reach an edge, then turn Move view off to fold. Fit paper restores the full view. Match every edge of the target; a nearly full percentage can still leave a small corner to fold.

Tips for matching the target shape

Start with a straight edge of the target and imagine where the paper needs to land. A crease sits halfway between the point you grab and the point it folds onto. Later folds act on the layers you have already made, so the order matters.

Try a fold, check the preview, and undo if the shape moves away from the target. There is no timer: take your time and experiment.

Keyboard shortcuts: Focus the board first. U undoes, R restarts, H gives a hint, and F toggles fullscreen. Enter moves to the next puzzle after solving. Press Esc to cancel a drag or leave fullscreen. Folding uses a mouse or touch.
