Lines X

Lines X is a single-player Numberlink puzzle game. You solve a series of grid levels by drawing paths between matching colored points.

Plan each route so the connecting lines do not cross. A level is complete when its colored points are linked, letting you move on to the next puzzle.

The game includes 100 levels, a level-select screen, multiple color themes, and ambient soundtracks. Its central puzzle mechanic remains the focus throughout.

Players who enjoy Lines X often describe its connect-the-points puzzles as simple, relaxing, and pleasant to play, with some appreciating the minimalist look and ambient music. Other recurring comments say the puzzles are too easy or the 100-level set is brief. Many reviews also criticize the large number of Steam achievements and their interruptions.
