Test Drive 6 on the Game Boy Color brings the Test Drive 6 experience to the handheld's capabilities, but with some limitations. The game features a limited selection of cars and tracks, and a top-down view perspective.
The game includes 12 licensed sports and muscle cars , down from over 40 in the console version, as well as 24 tracks set in 12 cities to select from. Players can choose from single races, tournaments, and the cop chase mode. The tournament mode consists of seven different cups, which must be won in order, with easier cups starting with only two laps and increasing to eight laps in later ones.
The game offers money and upgrade points as rewards for winning races, which can be used to buy new cars or improve their performance. Money is also used to purchase power bursts, which give short speed boosts during a race. The cop chase mode allows players to play on tracks unlocked in the tournaments, with the goal of handing out tickets to other cars on the track within a time limit.
