About This Game

Guide squiggly little snakes into exactly the right nooks. Each stage presents an outline shape with awkward empty gaps inside, plus a wiggly snake of a given length waiting to be threaded through them. Using simple grid movement you steer the creature around corners and into position until it plugs the hole perfectly, and a level completes once every gap holds its matching snake. Early boards teach the ropes gently, while later puzzles demand genuine foresight about turning space and body length. It is a charming, brain-tickling spatial puzzle with a friendly cartoon look, well suited to kids learning to plan and adults who enjoy neat geometric solutions.

How to Play

On PC use the WASD keys or the arrow keys to move your snake one square at a time, and on mobile simply swipe in the direction you want to go. Maneuver the body until every gap in the shape is completely filled to beat the level. Plan the whole route before your first move, because a wrong turn can leave the snake too short for the final gap.
