Hard Puzzle: Color Lines

In the logic puzzle «Hard Puzzle: Color Lines», you see round colored circles on a grid. Connect matching colors with lines so they do not cross, and so every empty cell is used. With each new level, extra colors appear, and there are fewer free cells. The positions of the circles change, new layouts appear, and previous solutions no not work anymore. As you draw, the lines between the circles slowly turn the grid into a clear color pattern.

How to play?

To complete a level, connect pairs of circles of the same color and fill the entire board. Lines cannot intersect. You earn stars for finishing levels, and the first gift unlocks after you clear five levels. If you get stuck, use the hint buttons under the game field. The goal of this color lines puzzle game is to link every matching pair and cover the whole grid. As you progress, you unlock new levels with more colors and harder shapes.
