What is One Line Draw?

One Line is a logic game based on "Graph Theory" and "Eulerian Paths." The core challenge is the "Continuous Stroke"—connecting all nodes without lifting the finger or retracing a path. It visualizes abstract math as elegant point-and-line puzzles, emphasizing "Starting-Point Selection" and "Path Foresight," testing logical deduction and spatial memory.

Description

Challenge your brain with the classic one-line drawing puzzle. Connect all the dots using a single, continuous stroke without retracing your path, featuring hundreds of levels that range from simple to mind-bending.

How to Play

Tap a node to start, then slide to connect others. The gameplay is "Path Coverage": the level clears once all lines are lit. The core rule is "Non-Overlapping"—a path cannot be used twice. Advanced levels introduce "One-Way Paths" and "Forced-Turn Nodes," requiring a full mental simulation of the circuit before the first move.

How to Get High Scores in One Line Draw

High scores are based on "Attempt Counts" and "Thinking Time." Completing complex graphs in a single continuous motion grants a bonus. The pro secret is "Degree Analysis"—nodes with an odd number of connections must be either the start or end point. Identifying these odd nodes instantly reveals the breakthrough for any complex puzzle.
