Professor Layton and the Unwound Future/Toy Car

The toy car is one of the three minigames that can be unlocked, accessed from the chest. It is automatically given to you during the story, along with a starter course.

The goal of the game is to get the toy car from the starting point to the ending tile, collecting every item on the course along the way. The toy car cannot be manually driven, but you can lay a limited number of tiles to make the car move in that direction or jump one tile forward. The tiles disappear after the car passes through them once. You can also change the initial direction of the car by tapping it. Some courses have drawbridges, which are only passable when lowered, and which can be raised or lowered by running over buttons on the course. You will fail the course if the car falls of the edge of the track or hits any obstacle.

Rewards
Beating all 10 courses unlocks The Hotelier's House, complete with 3 bonus puzzles.
