Play Color Lines Online

Color Lines is a 1992 puzzle game from MS-DOS Classic Games, developed by Gamos. It arrived during a period when many simple, focused puzzle titles found a home on personal computers, offering a clean interface and straightforward mechanics without the need for elaborate graphics or complex backstory.

You control a cursor to move colored balls on a 9x9 grid, one at a time, with the goal of forming lines of five or more matching colors. Each turn, three new balls appear in random positions, steadily filling the board. The challenge lies in planning several moves ahead, clearing clusters to prevent the grid from overcrowding. The game starts calmly but accelerates quickly, demanding sharp spatial reasoning under mounting pressure. It feels like a quiet but urgent race against your own accumulating mistakes.

Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
