Circles & Lines is a circular puzzle game for Android. Arc-shaped pieces drift in from the edge toward the moon at the center. You don't move the pieces — you spin the whole board with a swipe to catch them, and tap to drop. Complete a ring all the way around and it clears; the pieces left outside collapse inward, which can set off chains. Free, one-handed, 2–3 minute sessions, works offline. Small banner during play, full-screen ad at game over, no IAP.
