Ball mazes are normally solved by picking up the maze and manipulating the ball through the maze from start to finish. Thus, you use dexterity to solve the maze. You are not allowed to use dexterity in this way to solve Oskar’s “No Dexterity” ball maze.
You must keep the maze on the table and solve by rolling, rocking, tilting or tapping to move the ball from space to space.
