Play Fill Online Free
Fill is a line-drawing completion puzzle with a simple promise: trace a path that covers every empty cell inside the outline, and the shape fills with color once you succeed. The challenge is routing - your line cannot cross itself, and every move commits you to a path that must eventually close the loop.

Tips & Strategies
- Start from a corner or dead-end cell - they have only one possible entry and exit direction.
- Plan your route to end where you began; a line that ends in an isolated cell fails.
- On larger shapes, divide the outline into sections and solve each one before connecting them.
