One Line Draw
The constraint of drawing one continuous line through every dot creates endlessly fascinating puzzles. Plan your entire path before drawing and start from dead-end dots. The hexagonal grid variant adds diagonal complexity that keeps things fresh.
Start from endpoints that have fewer available paths to narrow your options early. Look for dots at the edges of the grid first since they constrain your route the most. If you reach a dead end, restart immediately rather than trying to backtrack.
How to Play One Line Draw
Each puzzle presents a grid of dots that you must connect with a single continuous line. Place your pen on any dot and draw to adjacent dots without lifting. You must visit every dot exactly once without crossing your own path. Later levels introduce colored dots and restricted zones that add complexity.
