Paper & Grain

Learn a fold or curl a corner, then try your own shapes in Free Fold. Take as long as you like.

Paper & Grain is a relaxing origami puzzle game. Start with a sheet of paper and see what you can make.

Pinch it into a crease, or pull a corner and watch it curl. The paper bends as you move a flap and settles flat when the fold is finished. Warm wood and softly textured paper give you a quiet place to work.

Eight lessons take you from a single crease to simple kites, folded letters, paper-cut shapes, and square-base studies. Follow the steps and diagrams, and open the Guidebook whenever you need help.

Free Fold starts with a blank sheet. Fold and unfold it, cut shapes, or add light pencil lines. Save editable sheets in your gallery and pick them up again later. Undo and Redo let you try another idea.

Use gestures to zoom and turn your work in 3D. Flip the sheet over or look beneath a fold while it is still partly open.

There is no timer and no losing. Work through a challenge or spend a few quiet minutes trying a shape of your own.

Paper & Grain is free to download and play, including all eight lessons and Free Fold. An optional Tip Jar supports development and does not unlock features. For iPhone and iPad running iOS or iPadOS 26 or later. Optimized for iPhone Duo, with optional folding along the device seam on iOS 27.1 or later. Touch controls work without a folding device.
