How to play
Every board has pairs of matching coloured dots. Drag from one dot to its partner to draw a line between them. Lines may not cross each other, and every square on the board must be filled before the board is solved. That is the whole rule.
- Drag from a dot to start a path; drag back over a path to erase it.
- Undo steps back one move. Restart clears the board.
- Each board gives you three hints if you want them.

Common questions
Does the game work offline?
Yes. Every board ships with the app. An internet connection is only needed if you choose to watch a rewarded video, or when the app checks for an update.
I am colour-blind. Can I still play?
Yes. Turn on Colour-blind shapes in Settings and each colour is marked with its own distinct shape, so you never have to rely on hue alone.
Where is my progress stored? Will I lose it?
On your device only. There is no account and nothing is uploaded, which also means progress does not transfer between devices and is lost if you delete the app.
Do I have to watch ads?
No. There are no lives and no ads between levels. You can choose to watch a short video for a hint, or for 30 extra seconds in Time trial. A small banner may show under the board, and you can close it. The whole game is playable without watching a single video.
Why does the app ask about tracking?
So Google can show ads that fit you better. Saying no changes nothing about the game: you still get every board, just with non-personalised ads. You can change it later in your device’s Settings.
What are bridges and rocks?
From the Lake world, some squares are bridges: one line crosses left to right and another goes over the top. Lines go straight over a bridge and both lanes must be filled. From the Canyon world, rocks block squares; draw around them.
The “watch a video” button is missing.
That option only appears once an advert has actually loaded. If none is available — no connection, or no ad to fill the slot — the button is hidden rather than shown broken. The other options on that screen still work.
A board looks impossible.
Every board in the game has at least one valid solution. Remember that a path does not have to take the shortest route: paths often need to wander to fill every square. Undo, or use a hint.
