Color Link: Connect the Dots

Draw a line between every pair of matching dots. Lines may bend but never cross or branch — and when you are done, every square on the board must be part of a line.

How to play Color Link

• Each color appears as exactly two dots. Press on a dot and drag to its partner to link them.
• Lines run only up, down, left and right, one square at a time. They cannot cross or overlap another line.
• Drawing over another color cuts that line back; drag your finger back and it reappears.
• The puzzle is solved when every pair is linked and every square is covered by a line.
• Choose a board size from 5×5 to 10×10, or play the Daily puzzle, which is the same for everyone today.

Controls

• Drag from a dot (or from the end of an unfinished line) to draw. Drag back over your own line to shorten it.
• Undo takes back the last line, Hint draws one correct link, Clear wipes the board.
• Numbers shows a number on every dot so pairs can be matched without relying on color.

Tips

• Dots on the edge and in corners have the fewest ways out, so link them first.
• If two dots of the same color sit close together, the line between them is usually short — and the long, winding line belongs to someone else.
• An empty square with only one free neighbour is a dead end that no line can fill: rethink the lines around it.
• A move counts each time you switch to a different color. Linking every pair in one stroke each earns a perfect score.

FAQ

Does every puzzle have a solution?

Yes. Every board is generated from a complete solution that fills all squares, and a solver checks it. Most smaller boards have exactly one solution.

I am color-blind. Can I still play?

Yes. Tap Numbers to label every dot, or turn on color-blind friendly colors in Settings, which switches the numbers on automatically.
