This is guide of making Lego maze from 2 baseplates, bricks and Technics liftarms.
Step 1: Step 1: Baseplates.
Baseplates are very good as floor and ceiling for the maze.
Step 2: Step 2: Add Bricks to Form the Maze
Now add bricks to one plate to form the maze. You will need to create a border with one exit and one entrance.
In the middle, but bricks to form the maze. This example have few complex places.
First one is a trap. If ball get there, it would be hard to get it out.
Second one is a T-intersection, where ball need to be directed to side path.
There are many other simpler elements that will delay of passing the maze.
If maze intended for kids <12 years old, I recommend to remove trap and T-instersections.
For players who love puzzles, more complex maze could be made. It could include more traps, O-rings and other complex sections.
Step 3: Step 3: Add Liftarms
To connect second baseplate, add liftarms from Lego Technic. They are great to connect 2 parts from top sides.
No need to cover all bricks with liftarms. You have to cover all border, to hide all hints from the player. In the middle you need to have at least 9 parts, to give good enough structural hardness to maze. Without parts in the middle, ball could stuck if someone press on both baseplates.
Height of brick and liftarm is good for the minifig head and for the small ball. For balls used in GBC, you will need to add an extra plate/brick level.
You could also cover path with tiles, that will require adding extra layer of bricks, to give enough height.
Step 4: Step 4: Add 2nd Baseplate
Put second baseplate accurately on the top. You may need to press hard so it will stick to liftarms.
Mark with small tile/piece entrance to the maze. I used green flower for the entrance and red flower for the exit.
Your maze is ready. Give it to someone to try and observe. Adjust maze if needed to make it more fun.
Step 5: Step 5: Enter the Maze
Zoe: There should be many treasures o the other side of the maze. MST2, could you use your sensors to find path?
MST2: Affirmative. I'm able to solve any maze. Estimating maze size and complexity...
Zoe: Great! Then show the path.
MST2: Sonar and night vision are switched on. Expected travel time is 21 minutes. Follow me.
(MST2 is abbreviation for MazeSolverType2).
Step 6: Step 6: Exit the Maze
MST2: Mission accomplished in 17 minutes. Zoe, you probably never thought that I could be that fast!
MST2: Waiting for the new orders.
MST2: Zoe? Zoe??? ....
