Rules of the Game

1. Start by selecting a shape from the given options. Each shape consists of a specific number of squares.

2. Place the selected shape on the grid by clicking on an empty cell. You can rotate the shape by clicking on it again.

4. Once a shape is placed, it cannot be moved or rotated again.

5. Your goal is to fill the entire grid with the given shapes, connecting them in a single line without any overlaps or empty spaces.

Strategies to Excel

1. Start with the corners: Begin by placing shapes in the corner cells of the grid. This allows you to create a solid foundation and build the line outward from the corners.

2. Utilize the edges: Along with the corners, the edges of the grid provide a good starting point. Try to fill the edges with shapes that can connect to multiple other shapes, allowing for more flexibility in expanding the line.

3. Plan ahead: Analyze the given shapes and grid before making any moves. Try to visualize how the shapes can be connected to cover the entire grid without any gaps. Planning ahead will help you make more strategic decisions and avoid dead ends.

4. Rotate wisely: Rotating the shapes can often open up new possibilities for connecting them. Experiment with different rotations to find the best fit for each shape.

5. Clearing obstacles: Sometimes, certain shapes may block the path for further connections. Look for opportunities to clear these obstacles by filling adjacent cells, allowing for the line to continue.


Fill One Line is a challenging and addictive puzzle game that requires logical thinking and careful planning.
