Fill the blocks with one line
About Fill the blocks with one line
Fill the blocks with one line is a brain-training puzzle built around one deceptively simple rule: draw a single continuous line that passes through every block on the grid, without lifting your hand or crossing the same spot twice. Several scenes show gray rounded squares sitting adjacent to the colored tile clusters, unconnected by the line. In one scene, a continuous dark green line threads through a series of bright green rounded squares arranged in a non-uniform grid. Several scenes also show a single white circle marking one end of the continuous line within a colored tile.
How to Play Fill the blocks with one line
The goal is to draw one unbroken line that covers all the blocks. Planning the route before committing matters, because a wrong turn can leave sections of the grid unreachable. Difficulty rises with each level, so the grids grow more demanding as progress continues.
