How to play
- Draw one loop through the centers of the squares. It can’t cross itself or branch, and it must pass through every pearl.
- On a black pearl the loop turns, then goes straight for at least one more square on both sides.
- Through a white pearl the loop goes straight, then turns on at least one side, in the square just before or just after.
- Drag from square to square to draw. Tap the side of a square to draw across it, tap again for ×, and once more to clear it.
Keyboard: arrows move, shift + arrow draws a line, alt + arrow marks ×.
