How to play Pearl
Trace a single unbroken loop through every pearl. White pearls sit on a straight passage with a turn beside them. Black pearls sit on a turn with straight passages beside them.
On this sample: Drag center to center to draw, reverse to erase, or tap an edge to cycle its marker.
- The finished route is one closed loop and never crosses or branches.
- Pass straight through each white pearl, then turn in at least one adjacent cell.
- Turn on each black pearl, then continue straight through both adjacent cells.
