Cosmos Lines Draw each numbered path across the cosmic grid in one continuous stroke.
Drag from numbered circles to cover the required grid cells, stay within the move allowance, and solve larger multicolor boards with fixed-direction crossings.
One-stroke pathsDrag each numbered line continuously
Numbered startsThe number sets the required path length
Cosmos Lines is a polished one-stroke puzzle on a space-themed grid. Start at a numbered circle and drag a continuous line across the required number of cells while fitting it around the other colored paths.
By Level 15 you face larger multicolor boards with more paths to weave around one another. Later stages add crossing points with fixed travel directions, so you plan each stroke before you drag.
Numbers define each line
Use the value inside the starting circle to determine how many cells that continuous path must cover.

Cosmic strokes
Drag one continuous cosmic path
Read the numbered starts. Identify each colored circle and the path length required by its number.
Plan around other colors. Reserve enough grid space for every line before committing the most restrictive route.
Drag one continuous path. Press a starting circle and trace through the required cells without breaking the stroke.
Respect crossings and moves. Use fixed-direction passages correctly and finish the board within the displayed move allowance.
Good to know
Calm grids, careful strokes
The game opens directly on a drag-to-draw Level 1 tutorial.
By Level 15 you face larger boards with more colors to fit together.
Later boards add larger grids and fixed-direction crossings.
Touch or device-mode dragging is the intended way to draw lines.

Cosmos Lines guide
Solve the tightest line first
Solve the most constrained path first. Short numbered lines and fixed-direction passages often have only one practical placement, while open areas can absorb more flexible routes later.
Count cells before dragging
Use the number at the starting circle to identify possible endpoints and reject routes that are too short or too long.
Protect fixed-direction crossings
Reserve the approach and exit required by a crossing before another color blocks that corridor.
Use the move counter as feedback
If repeated redraws consume the allowance, reset the board and test a different order for the most constrained colors.
Questions
Cosmos Lines FAQ
What do the numbers mean in Cosmos Lines?
A number marks the starting circle and indicates how many grid cells its continuous line must cover.
How do I draw a line?
Press the numbered start and drag one continuous stroke through the intended grid cells.
What changes in later levels?
Later boards become larger, add more colors, and introduce passages with fixed travel directions.
Can I play Cosmos Lines in a browser?
Yes. Cosmos Lines runs in the browser player on this page. You can drag the cosmic paths here without a separate download.
Ready for another cosmic stroke?
Return to the grid and drag the next numbered path in one continuous line.
