Tonka: On the Job is a Tonka game that was released on November 17, 2006, for Microsoft Windows and Game Boy Advance, developed by Webfoot Technologies and published by THQ. Tonka On the Job is a light simulation game that allows players to construct and operate vehicles based on the American Tonka franchise of toy trucks.
Typical trucks such as Mighty Dump, Mighty Front Loader, Toughest Mighty, Mighty Cement Mixer, Mighty Crane, and others are used in different scenarios to build foundations, dig canals, clear trees, and more. Every job starts at the Tonka Garage by deploying a vehicle. The gameplay is shown from a bird’s-eye view in small 2D-scrolling environments with dirt yards, cities, gravel pits, and forests.
Every vehicle has a specific use. For instance, Mighty Dump can carry up to four loads of dirt and can dump the load anywhere. Jobs gradually become more complex as more vehicles are available, and the player has to switch between them to complete the task. For instance, the Mighty Front Loader is used to pick up certain types of dirt to load it onto the Mighty Dump, which can transport it more efficiently.
Once deployed, it is possible to switch between vehicles on the fly. Sometimes, additional tasks appear during a job with a time limit, such as unexpected fires that can be put out with the Rescue Fire Truck. Completing these is usually not required, but is rewarded with bonus fuel. The performance per job is rated with up to three stars. Next to completing a job, the game, for instance, also takes into account fuel efficiency, which is at its best if no redundant driving is done and the vehicle stays on the roads as much as possible.
Later levels introduce dodging traffic. Special actions tied to specific vehicles also require more fuel. Most tasks have specific steps, such as clearing, grading, and constructing, but these do not always need to be completed in a fixed order. Often, there are multiple approaches or solutions to get the job done. The game can be played as a series of jobs or with free play for unlimited construction and destruction through deformable moments. The GBA version contains 11 trucks and the PC version 13.
