Pretty much all mazes can be solved by a simple rule!

Many mazes have unconnected or island walls in them. If you put your right hand on the wall as soon as you enter the maze, you can usually follow it all the way through to the end.

You can’t decide to put your right hand on the wall in the middle of the maze, though, because you could be unintentionally putting your hand on an island wall. It would cause you to go in circles within the maze. Faithfully follow the right hand wall from the beginning of the maze, though, and you will find the end easily.
