One Line is a charming and clever drawing game where your goal is to protect a clueless man from various dangers using just a single, continuous line. Whether it’s shielding him from pouring rain, swarms of bees, or the wrath of angry giants, each level presents a new situation that requires both creativity and precision. As the puzzles unfold, you’ll encounter increasingly complex threats like falling rocks, bullets, and other unpredictable hazards that demand strategic thinking. Your drawn line becomes a barrier, a shield, or even a trap to divert danger—but how you use it is entirely up to you.
Every level only requires you to keep the man safe for three seconds, but achieving that often involves inventive problem-solving. There’s rarely just one right answer, so experimentation is encouraged. Some levels might be solved with a simple arc, while others may demand intricate curves or unconventional approaches. As you progress, the game pushes your imagination further, rewarding players who can think outside the box and adapt quickly to new scenarios. And if a puzzle leaves you stumped, helpful hints are available to guide your next move.
