Andrea's Maze is a ball maze, based on a design by Andrea Gilbert. Andrea designed a big maze on paper, where there is one maze when you walk between the wall, and another maze when you walk on the wall. Andrea's maze features bridges, tunnels, spirals, loops and dead ends, which make both mazes highly confusing to solve. Andrea's Maze was first published as puzzle #173 in the book Puzzle Box vol.1
by Peter and Serhiy Grabarchuk.
The 3D-printed maze has two sides, where the walls at one side are the paths at the other side, and vice versa. The maze needs a 4 mm ball bearing to roll in the maze. Solve one maze, flip the puzzle and solve the other maze.
