Color Link
by Nebulark Studio · Puzzle · v1.1.0
Join every pair of glowing nodes with neon tubes. Tubes never cross and every cell must glow. A fresh five-puzzle Daily Ladder every day.
How to play
- Join each glowing node to its twin with a tube, and fill every cell to solve the puzzle.
- Drag from a node through neighbouring cells (no diagonals). Tubes can't cross: drawing over another tube cuts it back, and other nodes block your path.
- Drag back over a tube to shorten it, or press on any part of a tube to redraw from there. Undo takes back your last action.
- Stars: draw each tube in one go (one move per colour) and use no hints for three stars. A hint caps the puzzle at two.
- Daily Ladder: solve all 5 puzzles as fast as you can. Lower time is better, and each hint adds 10 seconds. Endless sizes are relaxed and unranked.
- Your run is saved as you play: press Continue on the menu to pick it up again.

About Color Link
Color Link is a calm but clever path puzzle on a glossy slate board. Drag a luminous tube from each glowing node to its twin through neighbouring cells. Tubes can't cross or overlap, and drawing over another tube cuts it back. A puzzle is solved only when every pair is linked and every cell is filled. Every puzzle is generated fresh and checked by a solver to have exactly one solution, so you can always reason your way through. Race the Daily Ladder, five puzzles from 5×5 up to 9×9, for the fastest total time (each hint costs 10 seconds), or relax in Endless mode on the size you like. A colour-blind option adds numbers to the nodes.
