One Line - Minimalist Logic Puzzle
Draw a single line that passes through every square of the grid.
One Line is a logic puzzle game that's easy to understand but increasingly difficult to master. Choose a starting square, draw a continuous path, and figure out how to visit each square exactly once.
š§© Simple rules, deep puzzles
Each level requires you to solve a grid in a single continuous line. The first puzzles are learned in seconds, then new constraints transform each grid into a true logic challenge:
ā¢ Directional arrows: some squares dictate a specific entry direction
ā¢ Walls: barriers block your path
ā¢ Inactive squares: holes change the shape of the grid
ā¢ Final squares: some levels require a precise arrival point
Each mechanic is easy to grasp, but their combinations create varied, elegant, and satisfying puzzles.
ā 300 Official Levels
Progress through the official One Line campaign with 300 handcrafted levels, spread across multiple worlds and 4 difficulty levels:
ā¢ Easy: Learn the basics
ā¢ Normal: Master the arrows and walls
ā¢ Hard: Solve more complex puzzles
