Block Snake is the heroine of the Block Trace game, her body has the ability to stretch to the required length. This is necessary so that at each level the snake can, with your help, fill all the free space, this is precisely the point of passing the level. The snake can only move in a straight line until its head hits the wall. Then you can change direction and move on if necessary. If there is any free space left, the task will not be completed and you will have to replay the Block Trace level.
