How to Beat Lines to Fill

To beat each level in Lines to Fill, players must successfully drag and drop colored lines into empty grid spaces without leaving gaps or overlaps. The key is to carefully visualize the puzzle before moving the pieces.

Here’s a step-by-step approach:

  1. Analyze the available spaces on the board.
