Today, I will show you how to build a Labyrinth/Maze. (Video DEMO)

1: Construct a base plate for it (At least 10x10x3 dimensions) and border it.
2: Once Bordered, place pillars (one block below height limit) with at least 1 block apart (place them as far as you want).
3: Place border walls between them in a maze-like pattern.
4: Locate pathways to end before 'finishing'.
