Link Line Puzzle

Link Line Puzzle is a flow-style connection game played on a colourful grid. Each board shows pairs of coloured dots, and your task is to draw paths joining every pair without any lines crossing or leaving gaps in the grid. Early boards teach the logic gently, larger grids and extra colours later force you to plan the whole board at once, because one tangled route starves the rest. Levels are hand-crafted and solvable in a few calm minutes, making it a perfect commute companion. Hundreds of stages keep the difficulty rising smoothly. Free to play in any modern browser, nothing to install.
