About Hard Puzzle: Color Lines: Logic Game of Paths and Planning

Hard Puzzle: Color Lines is a logic game built around connecting matching colored elements and drawing paths across a board. Every move demands planning, because the levels grow steadily more demanding — more colors appear, free space shrinks, and the margin for error tightens as you approach the final stages. Short levels and clear rules keep the experience approachable, while the genuine difficulty of the later puzzles gives your brain a real workout. Several views of the game show a central white square grid filled with colored squares and paths in yellow, green, orange, red, and blue.

How to Play Hard Puzzle: Color Lines: Connect All Color Pairs

Each level presents a board with pairs of colored elements. The goal is to connect every pair with a line and fill the board completely without leaving gaps or blocking other colors.

• Tap a colored element and draw a line to its matching pair of the same color.
• Lines must not cross one another.
• Extra gaps on the board are generally not allowed — the fill must be neat and complete.
• If a move goes wrong, use the undo or redo function, or restart the level entirely.

Controls

• Tap a colored element: Select it as the starting point of a line
• Draw (drag): Trace a path from the selected element to its matching pair
