Help and support
For Kakeya on iPhone and iPad. Requires iOS 17 or later.
How do I start?
During setup you may position and orient the needle without adding to its swept area. Tap Start Measuring, then move or rotate it to cover the target directions while meeting the area and move goals.
A gesture is not responding
In 2D, drag either enlarged endpoint to rotate, or drag the center to translate where allowed. In 3D, first choose Orient, XY, XZ, YZ, or Camera, then drag in the scene. Camera mode supports two-finger zoom.
Reference solutions
Tap Reference Solution Replay on a challenge. The demonstration resets its own trail and shows the swept region step by step without affecting your score.
Full Game and restoration
The Full Game is a one-time, non-consumable purchase unlocking levels 19–60 and all six 3D challenges. Levels 1–18, the daily free puzzle, and discoveries are free. Use Restore Purchases on the purchase screen or in Record → Settings with the Apple Account used to buy it.
Delete progress
