About One Line Draw
Original game information helps players decide whether this game fits their session.
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.
How to Play
Clear instructions make the page more useful and reduce quick bounces.
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.
Tips to Score Higher
Strategy content gives players a reason to read, replay, and explore similar games.
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.
