One Line

Welcome to the exciting puzzle-solving journey of One Line! You'll become the guardian angel for a cheerful but incredibly unlucky guy who's always getting into the most dangerous situations imaginable.
Draw one line to protect him from all threats—a simple but difficult task!

How to play One Line

Press and hold to start drawing the protective line. Use your mouse or finger on your phone to drag and create shapes to block dangerous objects. When you release, the line you draw will fall according to the laws of physics – it may tilt, fall, or slide if you don't plan carefully. The goal is to keep the character safe until the time runs out.

Try many different ideas because sometimes a simple circle, or a sturdy "roof," can be an unexpected savior!

Gameplay Tips

Don't let the line touch the character, otherwise, you'll accidentally harm the person you're trying to save! Create a stable base at both ends of the line to maintain balance. Carefully observe the direction of falling objects before drawing; one wrong line can cause the entire plan to collapse. Take advantage of empty spaces and corners to create an advantage.

We hope you have the best time rescuing and protecting the guy in One Line for as long as possible!
