Color Lines
Keep your phone upright for the clearest play area.
How to play
Connect matching colors and create long scoring chains on a clean board.
Save long routes and use short links when space becomes tight.
Controls
Tap/click an empty cell to connect the same-color endpoints; drag input is supported where shown.
What to do
Join each pair of colored endpoints without crossing another line.
How a round ends well
Every endpoint pair is connected and the board is filled.
When to try again
A crossing or dead-end route leaves the puzzle unsolved.
What is being tested
Orthogonal grid paths and limited cells turn route order into the central mechanic.
Three practical approaches
- Solve short edge pairs first.
- Leave the central row for the longest route.
- Use undo as soon as a connection blocks an endpoint.
Phone notes
Portrait suits small boards; rotate for larger boards.
Before you play
Board completion is not sent to a server and resets when the page reloads.
Input and display notes
Line color and endpoint shape both identify pairs where available.
