About Cozy Line

Cozy Line is a Frogame Original physics puzzle with one tool: a pen. A ball waits above, a goal sits somewhere below, and hazards fill the space between. You draw a line, it becomes solid, and gravity does the rest.

Ink is limited, which is the whole game. A generous swooping ramp might solve a level, but so might a two-centimetre nudge in exactly the right place — and only one of those earns three stars. Because the physics is deterministic, the same line always produces the same roll, so this is a puzzle about prediction rather than luck.

Thirty levels escalate from a simple slope to layered ramps, bounces and narrow gaps. Redraw as often as you like; each level also carries a verified reference solution you can peek at once if you're stuck.

How to Play

Press and drag to draw a line — the ink meter shows how much you have left. Release and the line turns solid, the ball falls, and physics plays out. Land the ball in the goal while avoiding the hazards. Redraw and retry as often as you want; less ink means more stars.

Cozy Line Tips & Tricks

  • Watch one failed run before redrawing — the ball's natural path tells you exactly where a nudge is needed.
  • Short lines placed precisely beat long ramps, both for stars and for reliability.
  • A steep line adds speed; a shallow one adds control. Choose based on what the hazard demands.
  • Draw under the ball's path, not in it — lines placed where the ball already is can trap it.
  • The reference hint shows one verified solution, not the only one; your shorter line may still score better.

Cozy Line FAQ

What limits my drawing?

An ink meter. Every level can be solved within it, and using less ink is what earns three stars.

Is the physics random?

No — it's fully deterministic. The same drawn line produces the same roll every time, which is what makes the puzzle fair.

Are all levels solvable?

Yes. Each of the 30 ships with a verified reference solution that the game replays automatically during testing.
