Color Dot Link Lines

Color Dot Link Lines is a relaxing logic puzzle where you connect pairs of matching colored dots by drawing lines between them. It is simple to understand, but filling the board perfectly takes real thinking.

The game is played on square grids that range from 5 by 5 up to 10 by 10, depending on the level and difficulty you choose. To complete a puzzle, three conditions must be met: every pair of same-colored dots must be connected, no lines may cross each other and every square on the board must be filled.

Early puzzles are gentle and help you learn the rules, while larger grids require careful planning. One badly routed line can block another pair, forcing you to rethink your approach.

The clean visuals and calm pace make it a great game for training your brain without stress.

Tip: connect pairs that are close to the edges or corners first. These lines usually have only one sensible route and help reveal the paths for the rest.
