Segovia mazes have underpasses. When there are marks on opposite sides of a "road" that match up, you can pass under one or more narrow roads
.
Also, if you encounter a small symbol, such as an asterisk 
, a circle 
, or a diamond 
, look for a matching symbol somewhere else in the maze and "teleport" there. You may not jump lines, but besides the regular roads 
, you can pass through open spaces that connect directly to the maze 
. This will be helpful to know before trying the Open-air maze, Tangles, Swirls, or Starburst.
These mazes are not terribly hard, though they do take more concentration than most mazes. You will have to take some time to get to the finish, but I hope you will have fun getting there!
You can either print the maze or do it in the browser window. If you do the latter, it may help to follow along with your mouse.
