Unblock: Parking Jam is a parking lot sorting game. The player works as a manager who must direct motor vehicles around other vehicles and obstacles in secure urban and suburban parking lots. They earn coins and gemstones for performance excellence.
The player clears up any parking jams by directing unblocked vehicles that face away from the lot to the street first. Some cars speed along the roads faster than others. If the player isn't careful during selections, they can cause temporary crashes that result in fines. They must deal with other obstacles as well. For example, they must unblock some vehicles by sliding black-and-yellow barriers.
Unblock: Parking Jam provides access to several special tools via ad views. The player uses a wrench button to randomly remove any car, double rotating arrows to flip the direction of a selected one, and a clock to make all vehicles travel at the same speed for one minute. Additionally, the game slightly rocks an unblocked vehicle forward and backward in place to indicate a revving engine.
When the player performs well, the game displays a happy emojis and pays them with coins. They receive gemstones after they complete specific daily and weekly achievements. If they perform badly, they see negative emoji and lose coins. They can track their time, winnings and losses at the end of each level.
