Frame the shot. Hold up both index fingers to form a rectangle and hold it steady — it auto-captures after about 2 seconds. Or pinch both thumb + index fingers together to start it instantly.
Countdown. A 3-2-1 countdown appears — stay in frame until the flash. That crop becomes your puzzle.
Arrange the pieces. Pinch a piece with one hand and drag it into its matching grid cell. Release the pinch to drop it.
Save it. When the board glows green, make a fist and hold it for about a second to save the finished photo to your strip.
Repeat & download. Do this up to 3 times, then use "download strip" or "download video" in the side panel.
Tip: good, even lighting helps hand tracking a lot. If a piece won't budge, try a slightly slower, clearer pinch.
