Total Turbo XXII is, as Lincoln calls it, the world's awesomest racing video game.
As Lincoln said, this is a racing game, so the goal is for the player to drive as best as they can. The player races down a highway where there are lots of cars and buildings that act as obstacles. Should the player collide into any of these, they will lose the game and it will result in a Game Over. The driver is the player's image virtually produced into the game. Their performance is judged based on side-screen feedback such as "Good", "Holy Cow" or "Dang, Girl" (the last one likely being because of who was playing at the time). The player can also drive off billboards to get ahead of Sunday Drivers and punch people down to get to where you need to go. The controller is a virtual wireless steering wheel.
The game first appeared in the episode "Driving Miss Hazy", where Lincoln tried to teach Leni how to drive by implementing the game mechanics to her like it was a driving simulator. At first, Leni wasn't ready to play because she needed to wear her special driving outfit and take a few sips of a soy pumpkin cookie crumble cream smoothie. When Leni was finally ready to play the game, she started off doing poorly by constantly driving into walls and buildings. She got so bad that her virtual self got out of the car before it exploded. The reason for her poor playing is because she wasn't going anywhere fun. Lincoln encouraged her that they were going to the mall. With that said, Leni started playing more confidently and managed to win the game by swerving past traffic, flying off billboards, and reaching her destination, even going so far as to having her virtual self knock over an old lady. Lincoln once had the highest score on the game, but Leni with her motivation managed to beat it.
However, this method proved to be a bad idea as when Leni took her thirteenth driving test, she failed yet again because she took the game mechanics into account and did exactly the same thing, thus resulting in the inevitable. This game may have been somewhat referenced in "No Guts, No Glori" were Lincoln pulls up a video game.
