Every puzzle is one drawing you have to get right in a single continuous line. Hold any dot, drag along the lines, and cover every path; thick ones take more than one pass. That is the whole rule — and it is enough to keep you stuck for ten minutes and then suddenly see it.
It is a hard game — not because it rushes you, but because you have to see something. There is no countdown and no way to fail, and there is a free set to start with, so you can find out whether that is your kind of puzzle before paying anything.

What makes it different
There is no failure state
You cannot lose, only pause. Lift your finger whenever you want and press the same dot again to carry on. Leave the puzzle, close the app, come back tomorrow — your half-drawn line is still there, waiting.
Nothing is hidden from you
Every rule is visible on the board. Line thickness shows how many times a path must be covered, arrows show direction, small numbers show order, and matching letters mark the portals. No text, no reading required.
Think first, then draw
The clock only starts when you first touch the board, so you can stare at a puzzle as long as you like for free. Stars reward planning: one for solving, two for solving without a hint, three for no hint and drawing it within the level's target time. A slip of the finger costs a second, not a star.
Stars only go up
Replay any level at any time to earn more. There is never a gap in your record that you cannot close.
Three tracks
- Tutorial — one new idea each, impossible to get stuck on
- Easy — multi-pass paths, one-way routes and ordered turns
- Normal — portals hide the starting point in plain sight
Every level is solvable by construction and hand-checked. Nothing is generated on the fly and hoped for. New levels keep arriving, and they are included.
Quiet by design
No ads. No subscription. No account. The game itself never goes online — it plays fully in airplane mode. Only the optional Apple services (iCloud sync, Game Center and the purchase) talk to Apple, and nothing about you is collected.
The tutorial and a free set of Easy and Normal levels cost nothing. A single purchase unlocks the rest and every level added later, and it is shared with your family. That is the only thing you can ever buy here.
Light and dark themes, following your device by default. Your progress syncs through your own iCloud account, so it survives a new phone.
