The Toy Car is a mini-game in Professor Layton and the Unwound Future. You get this mini-game in Hotel Duke. Luke Triton is not keen on it at the start because he sees the Toy Car as being too kiddish for him. Completing all courses will unlock The Hotelier's House in Professor Layton's Challenges.
To complete each course, you must guide the car around the course using the directional arrows to the right of the screen, which changes the car's direction. Every flag scattered around the course must also be collected before reaching the red tile.
