One Line Online

Draw One Line to protect your character from all kinds of unexpected dangers. A fun drawing game with lots of challenging little puzzles. 

How to play One Line?

In each level of this game, one or more dangers are heading for your character. Can you save him from falling objects, flying bullets, flesh-eating plants, and other  surprising dangers?

Look at the layout of each level and the objects you see. Quickly draw a single line to protect your character. Use your lines to draw a shield, deflect flying projectiles, or lock up the bad guys trying to harm you.

If your character can survive for three seconds after the dangers are let loose, you’ll win the level. Watch out, because the line you draw will turn into a steel bar once you let go. If it falls on top of your character or slams up against him too hard, he’ll knocked out as well!
