How to play

Tap grid edges to draw lines. Each tap toggles an edge on or off.
Use the pearl numbers as clues: a pearl marked '2' must have exactly 2 edges drawn around it.
Draw a single closed loop with no branches. When you think it's solved, tap VALIDATE.
If the loop is closed, connected, and all clues match, you win—faster times score higher.
