Fill Line: Cover Every Cell

Our take on Fill Line: Cover Every Cell

Reviewed by the LetsPlayFree editors ·

Fill Line is a peaceful logic puzzle. Starting at the marked cell, you trace one unbroken line that covers every block on the board. No cell may be entered twice, and diagonals are not allowed.

The idea is simple, but the boards grow with each chapter and valid routes become harder to see. You trace through neighboring cells without lifting your finger or releasing the mouse. It is neat and thoughtful, with no timer.

Looking for corners and cells with only one neighbor tells you where the line must start or end, which makes planning much easier on larger boards. Because there are no diagonals or revisits, the logic is clean and satisfying.
