Link Lines Online

by crokocat · Puzzle

Link Lines is a calm connect-the-dots puzzle on a glossy 3D board. Every colour has two dots: drag a line from one to the other. Lines can never cross, so the trick is to route them around each other — and a perfect solve fills every single square.

Draw by dragging square by square; if your finger skips ahead, the line follows along the way. Drag back along a line to shorten it, or start again from either dot.

Drawing through another colour cuts that line back to where you crossed it, so you can try an idea without clearing the board.

Every puzzle is made from one long path that runs through every square, cut into pieces — so each level has a solution that fills the whole board, and the ends of every piece become its dots.

Boards grow from 4×4 to 9×9 with more colours as you climb. Linking every pair finishes the level; filling every square earns three stars.

Stuck? The bulb draws one line for you, taking a star in exchange.
