The Fill One Line Puzzle game involves completing a grid by filling in a single line at a time. The player's task is to tap or click on the line to fill it with a solid shape. The core mechanic is the physical act of filling in the line, which has a domino-like effect, triggering further lines to be filled in succession.
The objective of the game is to complete the entire grid. The challenge arises from the need to anticipate and prepare for the newly generated lines that appear in response to each line filled. The player must adapt to these changes and ensure a smooth flow of filled lines to complete the grid.
