Labyrinths in the game world must either be completed or filled with something, and in the game Lines to Fills Online you will use the second option. The task is to fill all the voids with colored lines. To do this, there are two or more colored squares in the labyrinth, from which you will draw lines to wherever you see fit. A strict rule: do not walk twice in the same place and the lines should not intersect. There are five levels in the game, but wait, get upset, these are the main levels, each of which has a hundred sublevels. That is, you are waiting for as many as five hundred puzzles in Lines to Fills Online, and that's great.
