Dots Link — connect every pair of dots without crossing a line

How to play

A level shows a grid with several pairs of colored dots. Press a dot and drag through neighboring cells — up, down, left, or right — to draw a glowing path toward the matching dot of the same color. Paths cannot pass through other dots or through cells another path already uses, and a path's cells light up in its color as you draw. Drag backwards along your own path to erase it step by step, or start again from either endpoint to redraw a pair. There is no timer, no score, and no lives: the level is solved the moment every pair is connected, and solving it unlocks the next level.

What it helps improve

• Planning — Early paths block later ones, so you route each pair with the remaining pairs in mind — it improves your ability to organize steps and anticipate future outcomes.
• Problem solving — Each board is a constraint puzzle: the routes exist, and your job is to deduce them — boosting your skill in analyzing challenges and finding effective solutions.
