One Line Logic Puzzle challenges you to complete each stage by drawing a single continuous line through intricate layouts without retracing your path. This clicker game demands spatial reasoning and forward planning as you navigate increasingly dense puzzle grids. Unlike pattern-matching games, One Line Logic Puzzle requires you to map your route before committing, making every move count. Progress through 100+ levels where maze complexity escalates with each checkpoint. The minimalist interface strips away distractions, leaving only you and the geometric challenge. Tap and drag your line across the board to unlock each puzzle's solution. No timers pressure your decisions—only logic determines success.

How to play

Draw a single line through every empty square on the board using mouse, touchscreen, or keyboard navigation. Your path cannot cross itself, and you cannot skip cells. The game registers success when your continuous line completes the entire grid without leaving gaps. Early levels introduce basic U-shapes and simple corridors; later puzzles feature L-bends, spiral patterns, and rectangular dead-ends that force strategic planning. Click or tap to start your line at any position, then drag continuously to trace your solution. Release when complete. Wrong attempts reset immediately without penalties.
