Origami is a creative game played in the most natural way a foldable phone allows: the paper always folds exactly in half, just like the phone's hinge. You choose which half to fold and in which direction. In free mode you make any shape you like; in the shape puzzles you try to match a target silhouette using only folds through the middle.
How to play
- Hold the paper with your finger and rotate it. The fold always happens along the line in the middle of the screen, and that line never moves.
- Touch the top half of the screen and the top half folds; touch the bottom half and the bottom half folds.
- Fold the phone slightly: the paper folds all the way at once and leaves a crease. Open the phone to move on to the next fold.
- You can flip the paper, fold backwards, undo the last fold and save shapes you like to your gallery.
- The "Watch" button shows the finished shape large and replays the folds from flat paper.
Tips
- Rotation snaps in 5° and 15° steps; use 45° and 90° for symmetrical shapes.
- A shape can use at most 8 folds. In puzzles, picture the result first so you don't waste folds.
- In puzzle matching, a rotated or mirrored shape is fine; only the silhouette matters.
- Square and rectangular paper give different results. Try the same fold sequence on both.
Why always through the middle?
In real origami a fold can go anywhere on the paper. Here the rule is deliberately narrower: the phone itself only folds in the middle, so the paper does too. That one rule turns even simple-looking shapes into interesting puzzles. There are twelve shape puzzles, each of which can be made with folds through the middle only; a puzzle is solved when your silhouette closely overlaps the target.
What do you need?
Katla games run in the browser; there is nothing to download or install. The games read the phone's fold angle from its motion sensor, so they play best on foldable phones such as the Galaxy Z Fold and Z Flip. On a phone that doesn't fold you can tilt the phone with your wrist instead of moving the top half, and most games can also be played by tapping the screen. Motion sensors only work over a secure connection (https).
