Dot Lines

Dot Lines is a classic connection puzzle played on a grid. You connect same-colored dots and the lines can't cross each other. Block one color's path and you'll squeeze out the others — leaving the puzzle unsolved.

Simple enough for kids, soothing enough for adults to enjoy on a break. Works instantly in the browser — no download or account needed.

About Dot Lines

Each level uses a different grid size (starting at 5x5, going up to 10x10). More colors join in as you advance. Smart players start from corner dots — they only have one valid route, which frees up the center. Finish without using any hints and you earn 3 stars.

Why is it fun?

Getting stuck feels productive — undo a move, try a different corner. That classic puzzle satisfaction is here. A chill, mildly addictive game that builds logic skills for kids aged 7-12.

Is it safe?

Yes. No violence or scary content — just colorful dots and lines. Suitable for ages 6 and up.
