Musclecar Online is an entertaining racing game for Mac where your goal is to overcome the lap times of other users while playing this app's challenges. The application provides you with a different speed track every day, gives you access to an integrated raceway editor, and lets you choose from various car models before starting a new challenge.
You won't play against users from all over the world though. The idea of this game is that you get to compete on various tracks along with random 'ghost-lap' recordings of other Musclecar Online players, hence you won't crash onto any other car during challenges.
The better you lap time, the more coins you receive after you complete the given missions. Plus, you increase your chances in overcoming other users from all over the world on the available Leaderboard.
Another cool thing about this game is that you can share tracks created with the built-in editor with other Musclecar Online players.
The only aspect I don't like is the fact that the game comes with poor quality graphics and physics. Nevertheless, Musclecar Online provides you with a fun way to spend your spare time in front of your Mac computer and comes without a price tag. Hence, I'd say it's worth trying this game.
