Crowd Express features unique obstacles and block types that add depth and strategy to every level. Here’s a quick overview of how they work:

⏱️ Hurry

Buses move automatically after each action. You need to act quickly to avoid collisions or missing available slots.

❔ Hidden

The color of a bus remains hidden until the bus in front of it moves. Plan carefully, as you won’t know its color in advance.

🚪 Garage

The garage gate only opens for the next bus with the correct color. Sending the wrong color will not open the gate.

🔒 Lock

Locked buses cannot move for a specific number of turns. They will only become movable once the lock duration ends.

❄️ Frozen

Frozen buses are trapped in ice and cannot move. They will thaw automatically after a set number of moves.

📢 Megaphone

The megaphone instantly boards all passengers of a selected color from the queue .Use it to quickly clear or organize the waiting line.

🚍 Convoy

Convoy buses are linked together and must move as a group. The front bus must move first for the others to follow.

⛓️ Chain

Chained buses cannot move until the chain condition is met. If a chain shows a number, for example 10, you must send 10 buses to the parking area to break it and release the bus.

🍬 Gum

Gummed buses stick together and must enter a slot at the same time. They cannot be separated once attached.

🔑 Key

A key is required to unlock the bus. Until the key is collected, the bus cannot move.

🚦 Transit

Transit buses arrive already filled with mixed passengers. You must sort the passengers by color before proceeding.

🎨 Dye

Dye buses permanently paint their parking slot with their own color. The slot remains that color for the rest of the level.

📈 Overload

Lanes and slots have capacity limits. If you exceed the limit, the lane becomes blocked and traffic stops.

🦶 Kick Out

Some slots will eject a parked bus after a short time. Move or clear the bus before it is kicked out.

💣 Bomb

Bomb buses have a countdown timer. You must clear the matching bus before the timer ends to avoid penalties.

🟧 Cone

Traffic cones block entry from specific directions. You must remove the cone or find an alternate route.

🪜 Platform

Platforms shift or carry buses when aligned correctly. Timing is important to cross or ride them safely.

🔄 Rotate Bus

Rotate buses change their facing direction after each move. Align them with the exit before sending them forward.

💩 Mud

Mud tiles trap the first bus that drives over them, freezing it in place. The mud is consumed after one use, allowing the bus to move again afterward.

⚡ Shock

Shock buses temporarily disable all buses of the same color. That color becomes unmovable for one turn.

📦 Wrap

Wrapped buses toggle between open and closed states with every move. They can only be interacted with while open.

🙈 Cover

Covers hide the passenger queue and block visibility. You must remember the order of passengers to plan correctly.

⏩ Conveyor

Conveyor belts shift everything on them one tile in the shown direction after each move. Plan ahead to avoid unwanted repositioning.

🅿️ Slotter

Slotter buses provide a temporary advantage. When sent to the waiting area, they grant +1 additional slot.

🚜 Scoop

Snow piles block roads and prevent movement. Only buses with a scoop can clear the snow and open the path.

🧲 Magnetic

Magnetic buses stick when they collide with another vehicle.. Instead of returning to their starting position, they stop and remain attached.

Each obstacle introduces a new challenge. Understanding how they work will help you develop the right strategy to clear tough levels.

⭐ Starry Vehicles

Starry Vehicles can only park in spaces marked with a star. Regular parking spaces will not accept them, so plan your moves carefully to guide them to the correct destination.

🌀 Vacuum Bus

Vacuum Buses merge with vehicles of the same color when they come into contact. Use them strategically to create new opportunities and free up space.

👻 Ghost Vehicle

Ghost Vehicles remain inactive until another vehicle drives through them. Once activated, they become part of the puzzle and may affect your available moves.

⏰ Timer

Vehicles with Timers will wait until the Departure Time event once they are full. They cannot leave immediately, so make sure to account for their delayed departure when planning your strategy.

🚩 Flagged Vehicle

Flagged Vehicles change to the color shown on their flag after every valid move. Their color can change multiple times throughout a level, creating new sorting challenges.

🚁 Drone Vehicle

Drone Vehicles can fly directly to the departure stop if there is available space. This allows them to bypass normal movement restrictions and reach their destination instantly.

🪣 Gel Bucket

Vehicles carrying Gel Buckets splash gel onto two vehicles. Gel-covered vehicles have their colors hidden, making it harder to identify and sort them correctly.
