Rainbow Routes
Every dot on the grid has exactly one matching dot somewhere else, and your job is to connect every pair with a dragged line — but paths can't cross each other. Connect the wrong pair first and you can accidentally wall off the only path left for a different color, so solving it is less about speed and more about reading the whole board before committing to a single line.
How to draw a path
- Press and drag from a colored dot to start a path.
- Guide it to the matching dot of the same color.
- Running into another color's path blocks with a red flash — you'll need to route around it instead.
- Connect every pair on the board to unlock the next puzzle.
15 puzzles, three grid sizes
5×5 grids come first, with fewer pairs to juggle and more forgiving layouts. By 6×6 and 7×7, more color pairs are packed onto the board at once, so a path chosen too early can box in a pair you haven't gotten to yet.
Frequently Asked Questions
How many puzzles are there in total?
15, spread across three grid sizes — 5×5, 6×6, and 7×7.
What happens if a path crosses another color?
It blocks with a red flash and can't continue through — paths can only touch dots of their own color.
Why can't I just connect the nearest matching dots first?
Grabbing the shortest connection first often blocks the only route left for a different color pair.
