About Lumen Links
Lumen Links is a calm path-drawing puzzle. Each level is a grid with pairs of coloured lights, and your job is to connect every pair with a glowing line. Lines can't cross or branch, and a level only counts as solved when the paths cover every single cell, so the real challenge is finding the one layout that fits everything together.
There are 120 levels that grow from small 5×5 warm-ups to dense 9×9 boards, and later levels add prism cells where two lines may pass straight through each other. Every puzzle has been checked by a solver, so there is always an answer. A daily puzzle, optional hints, a colour-blind mode with shapes and star ratings for finishing without hints give you reasons to come back.
How to play
Drag from a light to its matching partner to draw a path. Drag over a path to cut it back. Keyboard: arrows move the cursor, Space starts or ends a line.
Tips
- Start with pairs that sit next to a wall or a corner: they usually have only one sensible route.
- If a corner cell is empty, some path must turn through it; work out which one can reach it.
- Prism cells let two lines cross only straight through, never with a turn.
